Statistical analysis of cascaded Rician fading channels

摘要

Exact-form expressions for the probability density function (PDF) and the cumulative distribution function (CDF) for product of n-Rician random variables (RVs) that are independent and not necessarily identically distributed are obtained. Moreover, novel expressions for the PDF and CDF of the instantaneous signal-to-noise ratio (SNR) in slow frequency nonselective independent and not necessarily identically distributed cascaded Rician fading channels are introduced and analysed. Exact-form expressions for the outage probability (OP) and average channel capacity are also derived. The average bit error probability (BEP) expression for phase-shift keying (PSK) signals operating in additive white Gaussian noise (AWGN) channel as well as in independent but not necessarily identically distributed cascaded Rician fading channels are derived. Numerical results are also provided verified by Monte-Carlo simulation.
