Wireless communication system in the presence of Rician and Nakagami-m short term fading

Reporter: Stefanovic M.

In this paper wireless communication system with maximal ratio combining (MRC) and selection combining (SC) with two branches operating over mixed Nakagami-m and Rician multipath fading channel is considered. In the first branch, desired signal experiences Rician fading and the second branch desired signal is subjected to Nakagami-m fading. Two cases are analysed in this paper. In the first case MRC receiver is used to reduce Rician and Nakagami-m fading effects on system performance and the second case SC receiver is used to mitigate Rician and Nakagami-m fading effects on outage probability. Probability density function, cumulative distribution function and average level crossing rate of wireless communication system receiver output signal are evaluated as expressions closed form. By using these expressions, outage probability, symbol error probability and average fade duration can be calculated. Numerical results are presented graphically to show the influence of Rician factor and Nakagami-m severity parameter on average level crossing rate.
