In this study PSK Model design and implemented using MATLAB Simulink and tested under multi-channel environment with BER improvement in each channel type, M-PSK Model examined under adjacent and co-channel interference by using two interfering signal. The model enables the modifying of the frequency offset and the power gain of each interferer and view the effects ona spectrum plot.} }
