چکیده
Performance analysis of switched-and-stay combining (SSC) and selection combining (SC) diversity receivers operating over correlated Nakagami-m fading channels in the presence correlated Nakagami-m distributed co-channel interference (CCI) is presented. Novel infinite series expressions are derived for the output signal to interference ratio's (SIR’s) probability density function (PDF) and cumulative distribution function (CDF). Capitalizing on them standard performance merasures criterion like outage probabilty (OP) and average bit error probability (ABEP) for modulation schemes such as noncoherent frequency-shift keying (NCFSK) and binary differentially phase-shift keying (BDPSK) are efficiently evaluated. In order to point out the effects of fading severity and the level of correlation on the system performances, numericaly obtained results, are graphically presented and analyzed. Key-Words: Switched-and-Stay Combining; Selection Combining; Nakagami-m fading channels; Co-Channel Interference; Outage Probability; Average Bit-Error Probability.

Energy Detection of Unknown Signals over Composite multipath/shadowing Fading Channels
In this paper, the performance analysis of an energy detector is exploited over composite multipath/shadowing fading channels, which is modeled by Rayleigh-lognormal (RL) distribution. Based on an approximate channel model which was recently proposed by the author, the RL envelope probability density function (pdf) is approximated by a finite sum of weighted Rayleigh pdfs. Relying on this inter...

We obtain generic expressions for the average error rate of multichannel reception of digital signals over correlated slowly varying Nakagami-m fading channels. The results are applicable to coherent detection with maximal-ratio combining as well as to diierentially coherent and noncoherent detection with post-detection equal-gain combining.
