信号插入导频-QPSK_raised cosine

siso信道模型，用于建立基础的点对点信道(SISO channel Model)

说明：  CCSDS推荐的LDPC编码方案，一系列参考标准，很好哦！(CCSDS recommended LDPC coding scheme, a series of reference standards, very good!)

There were downloaded documents wich can be very useful for those who exploring Wireless Sensor Networks. There given all the information and scripts to creat or build the model you need.

采用QPSK调制方式实现OFDM，在simulink上搭建的仿真模块，可以很好的学习OFDM，验证通过。(Achieved using QPSK modulation OFDM, built on the simulink simulation module can be good learning OFDM. )

相控阵雷达天线模型及仿真论文，非常好用，推荐(Phased array radar antenna model and simulation paper, very useful, recommended)

I=8，Fs=25KHz时的8个调幅（AM）信号的信道化发射机仿真结果，8路信道化软件无线电发射机MATLAB具体程序如下！(I = 8, Fs = 25KHz at 8 AM (AM) signal of the channel transmitter simulation results, 8-way channel software radio transmitter MATLAB following specific procedures!)

实现AWGN信道下，QPSK调制解调，系统的误码率(Achieving AWGN channel QPSK modulation and demodulation, the BER)

this is for calculate qam and it is very good to practice so good u can play

说明：  太赫兹通信方面的代码，可以对照相关文献看(Terahertz communication)
