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

LabView 用于串口接收读取缓冲的最佳时间间隔
LabView 用于串口读写数据读取缓冲的最佳时间间隔,在串口通信内容长度不确定的情况下,能完整接收数据并在接收结束之后尽快的停止接收,决定串口通信的效率。此vi经过小修改应该就能普遍适用。
