Abstract:

Diversity techniques have been applied to overcome multipath fading in the wireless communication. MIMO is a spatial diversity technique. With multiple transmit and multiple receive antenna, there are many ways to transmit data using coding and STBC and STTC are the techniques for which the performance can be evaluated. In present work Rayleigh Fading channel is considered. The analyzed parameter is probability of error. The necessary factor for wireless communication systems are Spectral efficiency, High transmission data rate, and reliability. Due to multipath, wireless channels suffer from attenuation and fading, without diversity techniques (time diversity, space diversity, frequency diversity). It would be difficult for the receiver to determine the transmitted signal because due to multipath multiple replicas of the transmitted signal will arrive at the receiver at slightly different times. The results taken are under Rayleigh multipath fading and modulation scheme used is BPSK.
