Simulation of Adaptive Channel Equalization for BPSK,QPSK and 8-PSK Schemes
The distortion and inter symbol interference caused by multipath effects of channel degrades the quality of signal transmission in transmission system of digital baseband. Adaptive channel equalization is used commonly to compensate these effects so as to increase the reliability of propagation. Recursive Least Squares (RLS) algorithm is most commonly used adaptive algorithm because of its simplicity and fast convergence. In this paper, simulation model of finite impulse response adaptive equalizer based on RLS is developed to reduce distortion caused by channel.
