Abstract:

The main contribution of this work is to extend the present multi-path fading channel (MFC) models in two directions.<br>First, the wireless communication system is viewed as a dynamical system where the channel constitutes the main plant of such a system. The random variables characterizing the magnitude of each multi-path component are generalized to random processes with time-varying statistics. It is claimed that the dynamics of both the log-normal shadowing and short-term fading channels is captured by the use of stochastic diffusion processes which emerge from mean-reverting Ornstein-Uhl

Abstract:

Multipath fading is one of the major practical concerns in wireless communications. A multipath transmission takes place when a transmitted signal arrives at a receiver by two or more paths of different delay. Such multiple paths may be due to atmospheric reflection or refraction, or reflections from buildings or other objects. A multipath fading channel is usually modeled as a time-variant tapped delay system. RAKE receiver can be used to detect the signal from the multipath fading channel. However, the number of delay taps, the time delay of each path, and the tap weight for each delay path

Abstract:

<p>Multipath fading is a very common phenomenon in signal transmission over wireless channels. When a signal is transmitted over multipath channels, it is subject to reflection, diffraction and refraction. This results in multiple versions of the same signal to arrive at the receiver, each of which has suffered from various path loss, time-delay, phase shift and often also frequency shift. The latter is a result of Doppler shifts, which is experienced whenever a relative movement between the receiver and transmitter or scatterers is present. The communication environment changes quickly over l

Abstract:

In this research, we introduce a model for a fading multipath channel. The channel impulse response consists of an infinite series of $ delta$-functions whose amplitude has a Ricean probability density function and whose phases are randomly distributed. The arrival times of the various pulses follow a non-homogeneous Poisson process. This model is well structured and quite flexible for characterization of mobile and indoor radio environment. A Bayesian decision approach is employed for the derivation of the optimal receiver for this channel model with additive white Gaussian noise (AWGN). Simp

Abstract:

Multipath frequency-selective fading can degrade the performance of a wireless communication system significantly as the data rate increases, e.g., when the data rate is as high as those of systems beyond long-term evolution (LTE)-Advanced. An effective method to combat multipath fading is a code division multiple access (CDMA) scheme. The objective of this dissertation is to present an effective method in designing nonbinary, secure, and optimum spreading and despreading pseudo noise (PN) sequences for CDMA multi-relay networks under frequency-selective fading by employing a maximum signal-to

Abstract:

Recently there has been considerable interest in spread spectrum techniques for use in commercial communication systems. One particular area where there may be considerable benefit is in mobile radio systems. Many of the difficulties presented by mobile radio communications result from the multipath fading which is present on the channel. This can lead to large reductions in the available channel capacity if measures are not taken to combat its effects. The use of diversity is highly effective in ameliorating the effects of fading. This research is concerned with an anti-multipath receiver arc

Due to the enormous capacity and performance gains associated with the use of antenna arrays in wireless multi-input multi-output (MIMO) communication links, it is inevitable that these technologies will become an integral part of future systems.

Due to the unprecedented spatial and temporal resolution they offer, wireless sensor networks are considered an enabling technology for the distributed monitoring of industrial, military, and natural environments. As these systems migrate into vastly different and novel applications, new constraints are discovered that affect network reliability and utility. For example, wireless sensors are typically statically deployed and, unlike mobile systems, cannot move to a new location for better radio reception. As a result, the signal fades caused by non-optimal environmental conditions can increase

Abstract:

碩士<br>國立臺灣大學<br>電信工程學研究所<br>95<br>The orthogonally multiplexed modulation (OMM) families are studied for the multipath fading channels. The OMM families include four different modulation schemes—OMOAM, OMOPM, OMO2AM, and OMO2PM, which provide a multitude of new multidimensional modulations by setting appropriate parameters and basis sets. Orthogonal frequency division multiplexing (OFDM) is one of the specific examples. In this thesis, by different basis assignments, the OMM signals are mapped to the OFDM signals to suit for fast Fourier transform implementation. Because of various applicatio
