APPLICATION OF THE McGEE UPPER BOUND TO COHERENT M-PSK AND M-QAM ERROR PROBABILITIES IN THE PRESENCE OF MULTITONE CO- AND INTER-CHANNEL INTERFERENCE

摘要

Using a linear exponential upper bound for the cumulative normal distribution originally published by McGee, a tight upper bound for the average BEP of a coherent BPSK system operating in the presence of N interfering sinewave signals is derived. The bound is expressible in a simple closed form involving exponential,cumulative normal, and modified Bessel functions and a simple application is shown. Extensions to coherent M-QAM and higher order PSK systems are indicated, and an application to a 16-QAM system is given.
