Abstract
Recently proposed bounds for the Marcum Q-function are applied to derive novel tight bounds for the bit error rate for differential quaternary phase shift keying transmission with Gray coding over an additive white Gaussian noise channel. Simple and accurate approximations are then proposed for the BER. The computational complexity of the final approximate expression is significantly lower than that of the exact expression.| File | Dimensione | Formato | |
