Wireless communication systems require different techniques of signal processing that improve the link performance in aggressive mobile environments. The mobile radio channel is dynamic due to multipath propagation and Doppler spread, these effects have a strong negative impact on the bit error rate of any modulation technique. Equalization, diversity, and channel coding are basically three techniques which can be used independently to improve received signal quality and link performance over small-scale times and distances. Inter Symbol Interference (ISI) must be compensated by using different equalization techniques created by multi path within time dispersive channels.
