指滤波器的性能与信号的特性取得某种一致，使滤波器输出端的信号瞬时功率与噪声平均功率的比值最大.即当信号与噪声同时进入滤波器时，它使信号成分在某一瞬间出现尖峰值，而噪声成分受到抑制。-In signal processing, a matched filter (originally known as a North filter[1]) is obtained by correlating a known signal, or template, with an unknown signal t

这个例子展示了如何用波束形成来模拟点对点MIMO-OFDM系统。多输入多输出（MIMO）组合和正交频分复用（OFDM）技术已在最近的无线标准的采用，如802.11X，提供更高的数据传输速率。由于MIMO采用天线阵，波束形成可以提高接收信噪比，进而降低误码率。(This examples shows how to model a point-to-point MIMO-OFDM system with beamforming. The combination of multiple-input-m
