最近，由萨贾德艾哈迈德高锐 [4] 提出了 OFDM 移动通信系统的优雅的信道估计方法。他讨论了在 OFDM 信道估计及其在 MATLAB 使用试点基于的块的 LS 和 MMSE 类型的信道估计算法。他出发进行了比较研究 OFDM 使用 BPSK 和 QPSK 上不同的渠道，其次是建模的 LS 和 MMSE 估计在 MATLAB 上的。最后，不同的模拟结果

We simulate uncoded BER of BPSK modulated data as a function of SNR

1.why there is a spike at every peak of current wave form? how to eliminate this? 2.actual current before filtering is around 6 amps peak , but after filtering it is giving 8.5 amps ,even after changing KP,KI values in PI controller reference value is not coming down...

描述了异步通信和同步通信的的概念还有对两者的区别做出了详细的讲解(Describe the concept of asynchronous communication and synchronous communication and make the detailed explanation to the difference between the two)

2PSK调制器的设计,在通信原理教学中应用MATLAB语言，可借助MATLAB方便的绘图性，把信号的频谱用MATLAB图形,很好地展现给学生，这样学生可以通过形象的图形来掌握抽象的理论，从而更好地理解原理．-2PSK modulator design, principles of teaching in the communications applications MATLAB language, can take advantage of MATLAB graphics and convenient, the spectrum signal using MATLAB graphics, a good show to the students so that students can grasp the image of the graphics to the theory of abstract to better understand the principle.
