Performance analysis of QAM in a two-wave with diffuse power fading environment

This letter investigates the average bit error rate (BER) performance of quadrature amplitude modulation in a two-wave with diffuse power (TWDP) fading environment. In TWDP fading, the received signal is composed of two specular components in addition to the diffuse component. The cumulative distribution function of TWDP fading is used to derive the BER expression in closed-form. Numerical and simulation results are presented to show the impact of different TWDP fading scenarios on the error performance.
