Relay deployments promise to alleviate the limitations of conventional macrocell networks, such as poor indoor penetration and coverage holes in a cost-efficient way. In this context, the capacity of the wireless relay link between a relay node (RN) and its serving base station (BS) has a crucial impact on the end-to-end performance. The deployment flexibility of RNs, which mainly stems from th...

Diversity combining techniques play an important role in combating the destructive effects of channel fading in wireless communication systems. In this work we present a blind diversity combining technique for Rayleigh flat fading channels based on Hammerstein type filters. We show that the performance of this technique is very close to ideal MRC system which is accepted as an optimum receiver ...

The performance of energy detection (ED) for independent and identically distribution (i.i.d.) signal models is analyzed over generalized composite non-linear line-of-sight (LOS) and non-line-ofsight (NLOS) shadowed fading scenarios. The novel expressions for ακ-μ/Gamma and α-η-μ/Gamma fading channels have been derived to approximate by using the mixture gamma (MG) distribution under low instan...

Wireless mobile ad hoc networks (MANETS) are self configuring, dynamic networks in which nodes are free to move. In mobile ad hoc networks, the major performance constraint comes from path loss and channel fading. This project implements a channel adaptive routing protocol which extends the Ad hoc On-Demand multipath Distance vector (AOMDV) Routing protocol to accommodate channel fading. This c...

In this paper, we propose a model to simulate a wireless fading channel based on Nakagami-m distribution with m>1. The Nakagami-m fading channel is the most generalized distribution as it can generate one-sided Gaussian distribution, Rayleigh distribution and Rician distribution for m equals to 0.5, 1 and >1 respectively. In this work we have proposed a method to generate a wireless fading chan...

The coherent reception of Direct Sequence Code Division Multiple Access(DSCDMA) signals in a multipath fading channel is considered. The channel model assumes independent paths with Nakagami fading statistics. This model includes the Rayleigh channel as a special case and a reasonable model for a frequency selective fading channel. The bit error rate(BER) performance of a RAKE receiver under va...

Multiple trellb coded modulation of constant envelope frequency and phaqe modulated signal sets (MTCM/FPM) is investigated for performance on the AWGN channel and on the one-sided normal, Rayleighand Rician-fading channels. The Nakagami-m fading model is wed as an alternative to the Ricianfading model to calciilate the error probability upper bound for trellis coded schemes on the fading channe...
