基于单片机的数字钟及秒表的设计
本程序是在单片机c51的基础上实现的数字钟和秒表的功能设计。此设计可是在时钟的基础上实现调表，也可以在时钟和秒表之间实现相互换，P2.0,P2.1,P2.2用于选择不同的数码管亮；P2.4用于调表，按下进入调表模式；p2.5使所调位加1； P2.6按键调表恢复数字计数或者秒表恢复数字钟；P2.7按键进入秒表状态。

Ofdm 技术的分析根据白噪声和失真的网络
关于利用 fft 功能调节和 ifft 解调 OFDM 传输的数据文件为.dat 或.wav 文件然后分析上具有添加白高斯噪声的 gui 窗口文件的输出输入中接受的项目 concetrates。也有用于 GUI 创建于 matlab，将代码的文件会导致在独立的应用程序。基带通信的应用是 PSK。虽然我用 MATLAB R2012a 要编译的版本可以也 matlab 的后期版本上测试中断开。

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
