Abstract :
The outage and average symbol error rate of a single channel system are analyzed over two-wave diffused power (TWDP) fading channels. An expression of characteristic function and outage probability of signal-to-noise ratio (SNR) for TWDP fading channel have been derived. Probability distribution function based approach has been followed to derive expressions of average symbol error rate for different coherent and noncoherent M-ary modulation schemes. Effects of the types of modulation and the fading parameters K and A on the system performance have been studied. The results obtained are verified with the special case results available in literature and by Monte Carlo simulation.
