Описание
Wireless communication systems require signal processing techniques that improve the link performance in hostile mobile radio environments. The mobile radio channel is particularly dynamic due to multipath propagation and Doppler spread. These effects have a strong negative impact on the bit error rate of any modulation technique. Mobile radio channel impairments cause the signal at the receiver to distort or fade significantly as compared to AWGN channels. Diversity is a powerful communication receiver technique that provides wireless link improvement at relatively low cost. In virtually all applications, diversity decisions are made by the receiver, and are unknown to the transmitter. This book provides the simulation results and information about the diversity combining technique like MRC, EGC and SC on different multipath channels.
