This paper studies the performances of a dual-branch switched-and-stay combining (SSC) diversity receiver, operating over correlated α-μ fading in the presence of cochannel interference (CCI). Very useful, novel, infinite series expressions are obtained for the output signal to interference ratio's (SIR's) probability density function (PDF) and cumulative(More)
In this paper, we present novel closed-form expressions for the probability density function (PDF) and cumulative distribution function (CDF) of ratio of random variable and product of two random variables for the cases where random variables are Rayleigh, Weibull, Nakagami-m and α-μ distributed. An application of obtained results in performance analysis of(More)
In this article, we investigate a two-hop relaying communication where all nodes are equipped with antenna arrays. We derive the multiple-input multiple-output (MIMO) processing matrices using the mean-squared-error cost function and assuming that each node uses only locally available channel state information estimates. Spatial processing at the base(More)
In this paper influence of co-channel interference (CCI) on the digital mobile radio systems operating over Nakagami-q (Hoyt) fading channels is investigated. Useful expressions are derived for average error rates over coherent and non-coherent frequency and phase-shift keying modulation schemes in interference limited system. The effect of selection(More)
This paper focuses on comparing performances of the diversity system which consists of selection combining receiver (selective SC combiner) with two input branches and performances of the diversity system which consists of SC combiner with four input branches. Supposition is that the signal has Rice distribution. The probability density function of the(More)
