在这封信中，我们考虑用有限脉冲响应（FIR）滤波器的频率选择信道和接收机的简单线性均衡的发射波束形成。由于最优FIR波束形成滤波器（BFFs）的闭合解似乎不存在，因此提出了一种有效的递推计算方法。我们的数值结果表明，对于典型的GSM/EDGE信道，短FIR bff可以接近[1]中最优无限脉冲响应（IIR） bff的性能，并且比单天线传输产生显著的增益。
In this letter, we consider transmit beamforming with finite impulse response (FIR) filters for frequency-selective channels and simple linear equalization at the receiver. Since a closed-form solution for the optimum FIR beamforming filters (BFFs) does not seem to exist, an efficient numerical method for their recursive calculation is developed. Our numerical results show that for typical GSM/EDGE channels short FIR BFFs can closely approach the performance of the optimum infinite impulse response (IIR) BFFs derived in [1] and yield significant gains over single-antenna transmission.
