生成2KHz和8KHz的混合信号，使该信号通过上述滤波器，观察滤波前后的波形变化和频谱分布情况。 在改信号中加入高斯白噪声，观察滤波前后的波形变化和频谱分布情况。-2KHz and 8KHz generation mixed-signal, so that the signal through the above-mentioned filter, filter before and after observation of the waveform and spectrum distribution of the changes. Add to the signal in white Gaussian noise was observed before and after filtering the waveform and spectrum distribution of the changes.

We investigate the case of independent Rayleigh faded paths between antenna elements and find that with high probability extraordinary capacity is available. Compared to the baseline n = 1 case, which by Shannon’s classical formula scales as one more bit/cycle for every 3 dB of signaltonoise ratio (SNR) increase, remarkably withMEAs, the scaling is almost like n more bits/cycle for each 3 dB increase in SNR. To illustrate how great this capacity is, even for small n, take the cases n = 2, 4 and 16 at an average received SNR of 21 dB. For over 99 of the channels the capacity is about 7, 19 and 88 bits/cycle respectively, while if n = 1 there is only about 1.2 bit/cycle at the 99 level. For say a symbol rate equal to the channel bandwith, since it is the bits/symbol/dimension that is relevant for signal constellations, these higher capacities are not unreasonable. The 19 bits/cycle for n = 4 amounts to 4.75 bits/symbol/dimension while 88 bits/cycle for n = 16 amounts t
