Performance of MIMO-STBC Decode and Forward Cooperative Communications with Channel Estimation Error over Nakagami-m Fading Channels

In Cooperative Wireless Communication, system performance decreases due to the improper estimation of the channel. We analyzed MIMO-STBC based Decode and Forward (DF) Cooperation Communication System, considering the effect of error, arises due to the improper estimation of channel. We have considered Decode Forward (DF) based MIMO Space Time Block Code (STBC) Cooperative Communication Network ...

Symbol error probability of decode and forward cooperative diversity in Nakagami-m fading channels

In this paper, we provide closed-form expressions for the symbol error probability of decode and forward cooperative diversity systems, when operating over independent but not necessarily identically distributed Nakagami-m fading channels. The results hold for arbitrary number of relays, and refer to the M-ary QAM and M-ary PSK modulations. r 2008 The Franklin Institute. Published by Elsevier L...

Analytic Performance Evaluation of M${-}$QAM Based Decode-and-Forward Relay Networks Over Nakagami-q (Hoyt) Fading Channels

The present work is devoted to the analysis of a regenerative multi-node dual-hop cooperative system over enriched multipath fading channels. Novel analytic expressions are derived for the symbol-error-rate for M−ary quadrature modulated signals in decode-and-forward relay systems over both independent and identically distributed as well as independent and nonidentically distributed Nakagami−q ...

A Comparative Study of Relaying Schemes with Decode-and-Forward over Nakagami-m Fading Channels

Utilizing relaying techniques to improve performance of wireless systems is a promising avenue. However, it is crucial to understand what type of relaying schemes should be used for achieving different performance objectives under realistic fading conditions. In this paper, we present a general framework for modelling and evaluating the performance of relaying schemes based on the decode-and-fo...
