modulation

说明：  实现optisystem中matlab component的ofdm仿真。这是调制代码 解调代码在另一个程序里。(Realize ofdm simulation of matlab component in optisystem. This is the modulation code. The demodulation code is in another program.)

MIMO系统的多径信道仿真程序，带有接收端和发送端的相关性计算，符合非物理模型下的MIMO信道(MIMO system in multipath channel simulation program, with the receiving end and sending end of the relevant terms, in line with the non-physical model of the MIMO channel)

FBMC的各个模块的代码实现，适合FBMC入门参考。(Code Implementation of Each Module of FBMC)

介绍如何对NS2进行多信道多接口扩展，并支持动态信道分配。(NS2 introduce how to carry out the expansion of multi-channel multi-interface, and supports dynamic channel allocation.)

说明：  QPSK调制解调源文件 QPSK调制解调源文件(QPSK demodulator source QPSK modulation and demodulation source)

实现了polar在BEC信道下的编译码，画出了误码率图像(The encoding and decoding of polar in BEC channel is realized, and the bit error rate image is drawn.)

仿真对数正态阴影衰落和仿真了一个BPSK通信系统，并与AWGN信道下的理论误码率结果进行了比较(Log-normal Shadowing PL model;Simulate a BPSK communication system, comparing simulated with theoretical BER results under AWGN channel)

说明：  可以比较两种信道估计算法的BER和均方误差(The BER and mean square error of the two channel estimation algorithms can be compared)

学习LaBVIEW数据保存至EXCEL的很好的案例。(It is about how to save LabVIEW data in CSV.)

SIM卡为表示能够执行proactive command且支持SAT，它必须在文件EFphaseTKG EFsst中有相关数据。 Phase文件指的是SIM卡所支持的GSM标准的级数，值为3则指SIM卡支持GSM phase 2和设置下传功能（profile download)。SST文件包含支持哪些GSM性能的准确信息。(SIM card that can support the implementation of proactive command and the SAT, it must file EFphaseTKG EFsst have relevant data. Phase document refers to the SIM card supports the GSM standard series, a value of 3 means the SIM card supports the GSM phase 2 and settings transfer function (profile download). SST file which contains support for GSM performance of accurate information.)
