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

在DLL和主程序中使用接口实例共享变量,ImageList(可以扩充共享数据链接) 受一位网友之托。粗作，高手不要下。 你可以试着更改Edit框中的字 然后按下chang login name 这样可以在DLL得到相应的值。 粗作。高手不要下-In DLL and main program interface examples of the use of shared variables, ImageList (can be expanded to share data link) by one of the occasional users. Rough for, you do not have. You can try to change the Edit box and then press the word chang login name in the DLL would be a corresponding value. Rough for. Players do not have
