Error Probability Upper Bound for Coherently Detected QASK Signals with Cochannel Interference
A. Javed, R. Tetarenko · IRE Transactions on Communications Systems · 1979
A simple upper bound to the probability of error for a QASK system with additive Gaussian noise and cochannel interference has been derived using Cramer-Chernoff techniques. Numerical results for the QASK-16 system are given.
