QAM 4 Modulator and Demodulator based on ETSI TETRA Standard

QAM Radio in Matlab. Software defined radio with transmitter and receiver simulated in Matlab. 16-QAM.

一、 本程序采用16QAM调制方式，对一串2进制信源进行调制，用升余弦滚降函数进行基带调制，再调到高频信道；在信道上加入高斯白噪声，运用匹配滤波器解调，画出解调星座图，运用最小欧氏距离译码判决，计算误比特率。-First, this program uses 16QAM modulation mode, for a string of two binary source is modulated with a raised cosine roll-off function for base-ba

In this simulink model , 16-QAM modulation and demodulation is simulated .A square root raised cosine pulse shaped signal is modulated and given as input to the demodulator.The received signal is demodulated and given to the detector where it is m

QAM调制，解调matlab代码，包含BPSK，QPSK,16QAM,64QAM,256QAM,1024QAM,4096QAM。其中调制方式。代码通过验证。-QAM modulator,demodulator
