In this simulink model , baseband 8-ary PAM detection is simulated .A half-sine pulse shaped PAM signal is given as input to the detector.The received signal is matched filtered and down-sampled .The effects of symbol timing offset can be seen by varying the phase of down-sampling operation.The 8-ary PAM signal transmitted is recovered at the detector output.
