基于LBER的自适应天线波束形成

LBER Algorithm for Beamforming of Adaptive Antennas

自适应天线的空间信号处理能力证明了它是解决未来无线电通信容量瓶颈问题的主要措施之一。自适应天线的波束形成算法有很多，简单介绍了LMSE（Least Mean Square Error）算法、CMA（Constant Modulus Algorithm）算法，重点讨论了一种基于最小误比特（Least Bit Error Rate，LBER）的自适应天线空间波束形成算法，从误比特率的角度对这三种算法进行了仿真、比较，得出了分析结果。

The spatial processing ability of adaptive antenna has shown that adaptive antenna is one of the key-factors to solve the capacity problem of future wireless communication. There exists many algorithms for adaptive heamforming or noise reduction. In this paper two algorithms （LMSE、CMA） are simply introduced and a algorithm which based on least hit error rate （LBER） is detailed, simulated and compared with LMSE and CMA.
