信噪比预测与链路自适应
此程序根据不同的场景采用对应的方法预测无线通信中的链路信噪比,根据预测信噪比选择合适的编码效率和调制阶数进行链路自适应,以此应对过时信噪比对系统性能带来的恶劣影响。

labview实现TCP通信
采用服务器/客户机进行双机通信,通过局域网送至客户计.
在服务器的框图程序中,首先指定网络端口,并用侦听TCP节点建立TCP侦听器,等待客户机的连接请求,这是初始化的过程。
在用TCP节点进行通信时需要在服务器框图程序中指定网络通信端口号,客户机也要指定相同的端口,才能与服务器之间进行正确的通信。端口值由用户任意指定,只要服务器与客户机的端口保持一致即可。
在一次通信连接建立后,就不能更该端口的值了。如过的确需要改变端口的值,

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
