The effects of linear channel distortions on the performance of a 512-QAM system are studied. Performance degradation due to linear, parabolic sinusoidal amplitude and group delay channel distortions are calculated by means of computer simulation. It is shown that sinusoidal amplitude and linear group delay distortions degrade most significantly the system performance. Comparison of the results with that of a same symbol rate and as well as a same bit rate 256-QAM system are also given.
