The two wave with diffused power (TWDP) fading model is a very useful fading model characterised by two specular waves in the presence of other diffused waves and is applicable to both the Rayleigh and Rician fading channels as special cases. The performance of switch diversity with binary modulation schemes over the TWDP fading channel is examined. The four types of switch diversity investigated in this study comprise of the switch-and-stay combining, switch-and-examine combining, switch-and-examine combining with post-selection and scan-and-wait combining. The expressions of the average output signal-to-noise ratio (SNR) at the receiver and bit-error rate (BER) are derived and presented. The pre-determined SNR thresholds of the switch diversity over the TWDP fading channel are optimised to obtain the minimum BER. Analytical results are validated by simulation.

A unified analytical framework is developed using a general two-parameter received signal-to-noise ratio (SNR) model for two-hop amplify-and-forward (AF) relaying with a multi-antenna relay, to determine error performance of binary modulation schemes over independent but non-identically distributed Nakagami-m faded links. The multi-antenna relay employs selection combining (SC) and the destination adopts distributed SC. Exact analytical expression is obtained for the cumulative distribution function of received SNR. A pair of generalised closed form expressions for bit error probability has been obtained for two specific AF relay configurations.
