最小误码率波束的形成算法

在经典自适应波束形成算法中，常采用均方误差准则，但对于一个通信系统来说，误码率是评价其性能的一个很重要的参数。利用核密度估计方法，由概率密度函数得到系统误码率与波束权值的关系，提出了一种自适应波束形成算法，在迅速收敛得到系统较小误码率的同时，得到最优的波束方向。仿真实验证明该方法优于经典的最小均方误差方法。

Adaptive Beam-forming Algorithm Based on Minimizing Bit Error Rate

Mean square error approach is often adopted in classical adaptive beam-forming algorithm, nevertheless, the bit error rate is one of the most important parameters in a communication system. This paper proposes an adaptive beam-forming algorithm based on minimizing the bit error rate, and computer simulations demonstrate that the performance of this method is much better than that of the classical method based on MSE approach.
