Abstract
In this paper an approach to the performance analysis of a dual-branch switched-and-stay combining (SSC) diversity receiver, operating over interference-limited Ricean correlated fading environment, is presented. Infinite series expressions are obtained for the output signal-to-interference ratio's (SIR) probability density function (PDF) and cumulative distribution function (CDF). Using these new formulae, the outage probability (OP) and the average symbol error probability (ASEP) for modulation schemes such as noncoherent frequency-shift keying (NCFSK) and binary differentially phase-shift keying (BDPSK) are efficiently evaluated. Numerical results, presented into this paper, are graphically presented and analyzed, in order to point out the effects of fading severity and the level of correlation on the system performances.
Highlights
Space diversity reception, based on using multiple antennas at the reception, is being widely considered as a very efficient technique for mitigating fading and cochannel interference (CCI) effects and improving offered quality of service (QoS) in wireless communication systems
There are a number of papers concerning performance analysis of switched-and-stay combining (SSC) receivers, for example [12,13,14,15,16] Very useful, novel, infinite series expressions are obtained for the output signal-to-interference ratio (SIR) probability density function (PDF) and cumulative distribution function (CDF) of a dual-branch switched-andstay combining (SSC) diversity receiver, operating over correlated α-μ fading in the presence of cochannel interference (CCI) derived in [12]
Infinite series expressions for PDF and CDF of the output SIR for SSC diversity are derived. Important performance measures, such as outage probability (OP) and Average Symbol Error Probability (ASEP) for several modulation schemes such as noncoherent frequency-shift keying (NCFSK) and binary differentially phase-shift keying (BDPSK) are efficiently evaluated and shown graphically for different system parameters in order to point out the effects of fading severity and the level of correlation on the system performances
Summary
Space diversity reception, based on using multiple antennas at the reception, is being widely considered as a very efficient technique for mitigating fading and cochannel interference (CCI) effects and improving offered quality of service (QoS) in wireless communication systems. There are a number of papers concerning performance analysis of SSC receivers, for example [12,13,14,15,16] Very useful, novel, infinite series expressions are obtained for the output SIR probability density function (PDF) and cumulative distribution function (CDF) of a dual-branch switched-andstay combining (SSC) diversity receiver, operating over correlated α-μ fading in the presence of cochannel interference (CCI) derived in [12] This analysis has a high level of generality because α-μ fading distribution model includes as special cases, other important distributions such as Weibull and Nakagami-m ( the one-sided Gaussian and Rayleigh are special cases of it). Important performance measures, such as outage probability (OP) and Average Symbol Error Probability (ASEP) for several modulation schemes such as noncoherent frequency-shift keying (NCFSK) and binary differentially phase-shift keying (BDPSK) are efficiently evaluated and shown graphically for different system parameters in order to point out the effects of fading severity and the level of correlation on the system performances
