Relays can be used in cellular systems to increase coverage as well as reduce the total power consumed by mobiles in a cell. This latter benefit is particularly useful for mobiles operating on a depleted battery. The relay can be a mobile, a car or any other device with the appropriate communication capabilities. In thesis we analyze the impact of using relays under different situations. We first consider the problem of reducing total power consumed in the system by employing relays intelligently. We find that in a simulated, fully random, mobile cellular network for CDMA (Code Division Multip

The relay based cooperative network is one of the promising techniques for next generation wireless communications, which can help extend the cell coverage and enhance the diversity. To deploy relays efficiently with limited power and bandwidth under certain performance requirements, resource allocation (RA) plays an increasingly important role in the system design. In recent years, with the fast growth of the number of mobile phone users, great portion of CO2 emission is contributed by wireless communication systems.

The thesis investigates robust linear and non-linear transceiver design problems for wireless MIMO relay communication systems with the assumption that the partial information of the channel is available at the relay node. The joint source and relay optimization problems for MIMO relay systems are highly nonconvex, in general. We transform the problems into suitable forms which can be efficiently solved using standard convex optimization techniques. The proposed design schemes outperform the existing techniques.

This thesis focuses on transceivers design for interference MIMO relay systems. Based on the MMSE criterion, several iterative algorithms are proposed to jointly optimize the source, relay, and receiver matrices subjecting to the individual power constraints at the source and the relay nodes. These algorithms have better performance than some existing algorithms and provide a better performance-complexity trade-off which is interesting in practical interference MIMO relay communication systems.

This thesis is a case study research that look into the difficulty in engaging freight receivers in initiatives related to urban freight transport. The aim of the paper is to investigate how participatory processes could be formed for more successful outcomes and how the freight receivers could become more engaged in the processes. By conducting a qualitative research where primarily interviews with freight receivers and other concerned stakeholder were made, it was possible to distinguish differences and similarities in views and attitudes toward participation in freight related initiatives.

Wireless communication continues to make a profound impact upon our daily lives. The oft-touted benefits of high data rates and improved reliability via wireless communication are limited by its inherent drawbacks, including path loss, fading and interference. One promising strategy for overcoming these problems is to deploy nodes in the region between a transmitter and its intended receiver. These intermediate nodes can improve communication for this transmitter-receiver pair by receiving a transmitted message, processing it and relaying the processed output to the receiver. This transmission

Multiple antennas combined with cooperative relaying, called multiple-input multiple-output (MIMO) relay communications, can be used to improve the reliability and capacity of wireless communications systems. The precoding design is crucial to realize the full potential of MIMO relay systems. Full-duplex (FD) relay communications has become realistic with the development of effective loop interference (LI) cancellation techniques. The focus of this dissertation is on the precoding design for MIMO FD amplify-and-forward (AF) relay communication systems. First, the transceiver design for MIMO FD

碩士<br>國立成功大學<br>工程科學系<br>102<br>Nowadays, the explosive development on the number of mobile user and multimedia services cause a severe traffic overload problem in the cellular network. Data offloading in the Third-Generation Partnership Project (3GPP) is defined as critical scheme to cope with this issue. Furthermore, device-to-device (D2D) communications have been considered as a new data-offloading solution. The D2D communications underlay cellular networks infrastructure reduces the radio access network load and the core network load. Device-to-device (D2D) communication commonly refers to

碩士<br>淡江大學<br>電機工程學系碩士班<br>96<br>Although many researches on relay-based cooperative coherent communication systems have shown that the benefits of spatial diversity, saying cooperative diversity, can be achieved as the multi-antenna technologies do, the analyses primarily rely on the assumption that the perfect channel state information (CSI) is available at the receiver. In practical scenarios, the CSI has to be estimated and the effect of imperfect CSI on system performance needs to be analyzed. In this thesis, we study the channel estimation problem for amplify-and-forward (AF) relay-based
