用C语言编写的LDPC译码程序，希望对大家有用(Using C language LDPC decoding process, in the hope that useful)

opnet 仿真，陈敏老师2015年新书 opnet物联网仿真(opnet Simulation)

ofdm信道估计仿真（ls算法，mmse算法，还有一种改进的mmse算法lmmse，可以直接在马特拉并上运行）(OFDM channel estimation simulation (ls algorithm, mmse algorithm, as well as an improved MMSE algorithm lmmse, can be directly in the Matra and run))

此代码是关于BPSK-OFDM信号调制代码，简单编码叙述者整个调制过程，可直接运行出结果(BPSK-OFDM signal modulation code)

说明：  平方根升余弦滤波器作为发送滤波器和匹配滤波器，使用python语言。(Make the square root rise cosine filter as a send filter and a match filter, using the python language.)

在ofdm调制中运用压缩感知中OMP算法进行信道估计并与LS算法进行比较(Ofdm modulation using compressed sensing OMP algorithm for channel estimation and comparison with the LS algorithm)

采用GSM系统的GMSK调制方式，并画出出时频域图，计算BER，有利于了解GSM系统的调制解调。(Frequency domain using the GSM system GMSK modulation and draw the diagram, calculate the BER beneficial for GSM modem.)

说明：  维纳滤波matlab代码，对语音去噪有较明显效果，可做去噪算法借鉴(Wiener filter matlab code,It has obvious effect on speech denoising and can be used for reference in denoising algorithm)

olen法波束形成，可产生任意指定的波束图。仿真中的例子为cheb滤波器。也可自己指定(France olen beamforming, can produce any given beam pattern. Simulation example cheb filter. Can also specify)
