说明：  RS码的C实现，通过mex接口，在MATLAB中创建的LTE下行链路中测试，可跑出误码率曲线。(RS code is implemented in C, by mex interface, LTE downlink created in MATLAB test can be run out of BER curves.)

多组处理，仅展开一个区块的折叠效果(原生Js和jQuery版)，俗称“手风琴菜单”，习惯叫做折叠菜单，一个页面中布置了多组菜单，部分代码释义如下： 　　var navItem=iBase.Id(‘demo‘).getElementsByTagName(‘h2‘) //此处将jQ区块中的h2也取到了,所以页面会有个小小的错误 (Multiple sets of treatment, only one block to start folding effect (native Js and jQuery version), commonly known as accordion menus , used to be called folding menu, a page layout of the multiple sets of menus, the interpretation of the code is as follows: var navItem = iBase.Id ( demo ) getElementsByTagName ( h2 ) . // Here jQ block will also take to the h2, so the page will have a small mistake)

介绍了数字通信中的QPSK调制解调的原理，通过用Matlab编写脚本程序对QPSK通信系统的发射和接收过程的具体实现进行模拟仿真，绘出信号在理想信道和加噪信道中模拟传输时的时域图，并对各模块进行了频谱分析，所得到的结果与 理论基本相符，对于理解QPSK系统的性能并在系统的实际应用上作进一步的设计，提供了有效的参考依据。 (The introduction was done with the principle of the QPSK modulation and demodulation in digital communications，a script was written by using Matlab program to CalTy out a simulation of the QPSK communication system．which contains the concrete realization of transmit and receive process．The time-domain diagram is drew separately when the signal transmits in the ideal channel and in the channel with noise，spectral analysis of each module is also done，the results obtained with theoretical results in the main，which provides an effective frame of reference for understanding the performance of QPSK systems，and the practical application in the system to make further designed．)
