Description: 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-multiple-output (MIMO) and orthogonal frequency division multiplexing (OFDM) techniques have been adopted in recent wireless standards, such as 802.11x families, to provide higher data rate. Because MIMO uses antenna arrays, beamforming can be adopted to improve the received signal to noise ratio (SNR) which in turn reduces the bit error rate (BER).) Platform: |
