Abstract
It is demonstrated that the MBER criterion can adjust the weights of the beamforming more intelligently than the traditional MMSE criterion to reduce the bit error rate. This thesis researches on the MBER criterion and the adaptive MBER algorithm. We compare the difference between the MBER criterion and the MMSE criterion by showing the simulation results.
Multiple antenna arrays are often used to overcome the effect of channel fading which is caused by multipath interference. In chapters 4 and 5 ,we derive spatial correlation equations of ULA ,UCA and CRA for two types of angular spread distributions (uniform distribution and truncated Gaussian distribution).We also compare the difference between these antenna arrays by showing the bit error rate simulation results and discuss the relationship between BER and spatial correlation. In a multi-user mobile radio environment , we present simulation results to show that adaptive MBER algorithms have better performance than the traditional MMSE algorithm.
