LMS Equalizers for Different Blocks and over sampling factor Rayleigh Fading Channel with Normalized Impulse Response

Block based linear equalizers are used in communication systems for removing the effects of the channel degradation. Researchers have developed linear equalizers using different modulations techniques. This paper evaluates the BER performance of communication system for different over sampling factor of pulse shaping filters. The effect of the different number of transmitting blocks is also evaluated with different M-PSK modulations for the LMS linear equalizers over the frequency selective Rayleigh fading channel. The Rayleigh channel is modeled with multipath channels and normalized channel impulse response. For evaluating the performance of the linear equalizers M-PSK sizes are varied and BER is calculated. It is found that linear equalizers with normalized channel impulse response have better BER performance. It is observed that the BER probability is reduced with increasing the number of blocks. Performance is also compared for the different equalizer weights and block sizes.
