Abstract:

Approved for public release; distribution is unlimited<br>The U.S. Army's joint platform allocation tool (JPAT) is an integer linear program that was developed by the Army's Training and Doctrine Command Analysis Center and the Naval Postgraduate School to help inform acquisition decisions involving aerial reconnaissance and surveillance (R&S) resources. JPAT evaluates inputs such as mission requirements, locations of available equipment, and budgetary constraints to determine an effective assignment of unmanned aerial R&S assets to missions. As of September 2013, JPAT is solved using a rollin

Abstract:

Abstract This thesis concentrates on joint optimization of transmit power allocation and receive filtering in multiuser, multi-antenna communications. Due to the increasing number of wireless devices, the design of energy-efficient communication links is becoming increasingly important. In cellular mobile communications, reducing the average power consumption in uplink transmission is beneficial for users in order to extend battery life and, hence, energy efficiency in general. However, the power consumption of the high power amplifier (HPA) at the transmitter depends on the peak power of the

Abstract:

The energy management policy of a rechargeable wireless sensor network (WSN) needs to take into account the energy harvesting process, and is thus different from that of a traditional WSN powered by non-rechargeable batteries. In this thesis, we study the energy allocation for sensing and transmission in an energy harvesting sensor node with a rechargeable battery. The sensor aims to maximize the expected total amount of data transmitted subject to time-varying energy harvesting rate, energy availability in the battery, data availability in the data buffer, and channel fading.

Abstract:

Wireless network virtualization (WNV) is a promising technology which aims to overcome the network redundancy problems of the current Internet. WNV involves abstraction and sharing of resources among different parties. It has been considered as a long term solution for the future Internet due to its flexibility and feasibility. WNV separates the traditional Internet service provider’s role into the infrastructure provider (InP) and service provider (SP). The InP owns all physical resources while SPs borrow such resources to create their own virtual networks in order to provide services to end

Abstract. A two-way relaying system with amplify-and-forward technique, where relay stations (RSs) acquire the energy from transmission signal and interferences, is considered. The RSs use the energy to amplify the signal received from the transmitter and forward it to the receiver. Particularly, energy harvesting (EH) and time switching (TS) are deployed. Based on the TS architecture, we divide transmission time into two time slots, which are EH phase and information transmission (IT) phase. In the EH phase, the RSs harvest the energy from the received radio frequency (RF) signal. In the IT p

Abstract:

Wireless network virtualization is a promising avenue of research for next-generation 5G cellular networks. This work investigates the problem of selecting base stations to construct virtual networks for a set of service providers, and adaptive slicing of the resources between the service providers to satisfy service provider demands. A two-stage stochastic optimization framework is introduced to solve this problem, and two methods are presented for approximating the stochastic model. The first method uses a sampling approach applied to the deterministic equivalent program of the stochastic

Abstract:

In this thesis, bit-by-bit power allocation in order to minimize mean-squared error (MSE) distortion of a basic communication system is studied. This communication system consists of a quantizer. There may or may not be a channel encoder and a Binary Phase Shift Keying (BPSK) modulator. In the quantizer, natural binary mapping is made. First, the case where there is no channel coding is considered. In the uncoded case, hard decision decoding is done at the receiver. It is seen that errors that occur in the more significant information bits contribute more to the distortion than less significan

Algorithmically designed reward functions can influence groups of learning agents toward measurable desired sequential joint behaviours. Influencing learning agents toward desirable behaviours is non-trivial due to the difficulties of assigning credit for global success to the deserving agents and of inducing coordination. Quantifying joint behaviours lets us identify global success by ranking some behaviours as more desirable than others. We propose a real-valued metric for turn-taking, demonstrating how to measure one sequential joint behaviour. We describe how to identify the presence of tu

Hence, IEEE published 1900.4 standards in February 2009, which provided integration architecture for heterogeneous network. In this thesis, we enact standards for data transmission between core network and mobile devices. Also, we use common radio resource management architecture to integrate network environment and achieve optimal resource distribution. Wireless network resource distribution is an important issue. In this thesis, we propose a mo

碩士<br>國立交通大學<br>電信工程研究所<br>104<br>In this paper, the cloud radio access network (C-RAN) is considered to extend the transmission coverage via the distributed deployment of large scale remote radio units (RRUs). The benefits of C-RAN system deployment is distributed network with centralized management solution. The RRUs are more closer to the user equipments (UEs), power consumption can be reduced to overcome pathloss attenuation and enhance spectral and energy efficiency (EE). However, this type of structure can induce considerable computational loadings due to the centralized management mecha

Abstract:

碩士<br>臺灣大學<br>電信工程學研究所<br>98<br>The increasing rate on ubiquitous wireless broadband access drives the development of even better wireless communication technology. Both LTE-Advanced and 802.16m, potential candidates of so-called 4G standard, are capable of reaching over-the-air 1Gbps transmission rate which is required by IMT-Advanced. Although different in certain features, they both share many common key technologies, including OFDMA, MIMO, multi-carrier, relay support, etc. Relay operation is viewed as a highly efficient way to either increase cell coverage or enhance channel condition wit

Abstract:

碩士<br>國立臺灣大學<br>電信工程學研究所<br>101<br>Due to the nature of time-varying and frequency selective fading, wireless communication system can increase system throughput via dynamic resource allocation (time slot, bandwidth, power and bit), exploiting multi-user diversity. Multicast deliver the same content to several users in the same group to enhance frequency efficiency, but the channel conditions may vary greatly between users of the same group. Conventional approach selects the worst channel gain as equivalent channel gain of group’s sub-channel, limiting the system throughput. Aim to maximum fre

Abstract:

Multi-antenna processing is widely adopted as one of the key enabling technologies for current and future cellular networks. Particularly, multiuser downlink beamforming (also known as space-division multiple access), in which multiple users are simultaneously served with spatial transmit beams in the same time and frequency resource, achieves high spectral efficiency with reduced energy consumption. To harvest the potential of multiuser downlink beamforming in practical systems, optimal beamformer

碩士<br>國立臺灣大學<br>森林環境暨資源學研究所<br>93<br>The aim of this study was to examine the nestling sex allocation of a joint-nesting population of Taiwan yuhina (Yuhina brunneiceps). Most of Taiwan Yuhina breeds with joint-nesting strategy in the study site, and the linear hierarchy relationship within group members is obvious. Dominant males had larger wing chords than subordinate males, but there was no difference of body size between dominant and subordinate females. We assumed that the condition of males was more influenced by parental investment than that of females. I conducted the study at Meifeng
