Performance Analysis of Cooperative Networks With Relay Selection Over Nakagami- m Fading Channels

The performance of dual-hop Decode-and-Forward relaying with relay selection (RS) is analyzed over Nakagamifading channels. Assuming that the direct source-to-destination link is active, closed-form expressions for the moment generating and the cumulative distribution functions of a RS-based cooperation scheme that utilizes maximal-ratio diversity at the destination are derived. These expressio...

Performance Analysis of Cognitive Relay Networks Over Nakagami-m Fading Channels

In this paper, we present performance analysis for underlay cognitive decode-and-forward relay networks with the N th best relay selection scheme over Nakagami-m fading channels. Both the maximum tolerated interference power constraint and the maximum transmit power limit are considered. Specifically, exact and asymptotic closed-form expressions are derived for the outage probability of the sec...

Performance Analysis of TDMA Relay Protocols Over Nakagami- Fading

Several time-division multiple-access (TDMA) cooperative wireless relay protocols and their performances have recently been developed by Nabar, Bolcskei, and Kneubuhler. Their work, however, is limited to an upper bound-based performance analysis for Rayleigh fading. We thus provide an exact analysis of two of their protocols in single-relay and multiplerelay networks over independent identical...

Unified Analysis of Generalized Selection Combining over Arbitrary Fading Channels

We derive general, unified expressions for the probability density function, cumulative distribution function, and mean SNR of generalized selection combining operating over multibranch, arbitrary, correlated, non-identical fading channels. The expressions are written in terms of the joint probability density function of the branch signals and allow for the equalgain and maximal-ratio methods i...
