function y=myditfft(x) 《数字信号处理教程——MATLAB释义与实现》 用MATLAB语言编写的基2 DIT FFT子程序(function y = myditfft (x) " digital signal processing tutorial- MATLAB Interpretation and Implementation" MATLAB language with the base 2 DIT FFT Subroutine)

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 matched filtered and down-sampled .The effects of symbol timing offset can be seen by varying the phase of down-sampling operation.The signal transmitted is recovered at the detector output.
