Performance Comparison of Diversity Receivers over TWDP Fading Channels

A signal propagating in wireless channels encounters fading effect, which degrades the performance of wireless communication systems. Information about the performance of communication systems is significant for assuring service availability and sustainability, as well as quality of service in telecommunication networks. Bit error rate, average output Signal to Noise Ratio, outage probability, amount of fading, level crossing rate, etc. are some of the important performance measures for communication systems. One of the efficient counteracting methods that can modify the disparaging outcome of fading for superior performance of receiver is the diversity combining. Some of the important diversity combining schemes are selection combining, equal gain combining and maximal ratio combining. A comparative study of these diversity receivers over two wave diffuse power have been carried out to evaluate the impact of fading parameters K and Delta on their performance.
