摘要

基于最小误码率（MBER）准则的自适应算法，其具有远远优越于传统的最小均方误差（MMSE）准则的性能，但其高复杂度限制了其在实际中的应用。在基于MBER准则的基础上，提出了一种快速自适应波束成型算法，在保证低复杂性的同时，快速收敛于最优MBER解。更重要的是，相对与传统MBER算法，新提出的算法能得到更加优越的波束图，使其更适用于时分双工（TDD）通信系统。

Abstract

The performance of an adaptive algorithm based on minimum BER (MBER) was superior to the one based the conventional minimum mean square error (MMSE)

but the complexity is the limit on its application. A fast adaptive beamforming algorithms was proposed based on MBER

it had a low complexity and fast converge to the optimal MBER solution. More important

the proposed beamforming algorithm can obtain a better beampattern compared by the conventional MBER

which is very fit to the TDD communications system.
