Differential matched filter architecture for spread spectrum communication systems - Electronics Letters

Conclusion: We have derived new expressions for the symbol error rate performance of coherent M-ary phase shift keyed signals in slow nonselective Nakagami fading and additive white Gaussian noise channel. For integer values of the Nakagami fading parameter m, a closed-form expression is derived for the symbol error rate. However, for real values of nz, a simple formula which can be easily computed numerically is presented. The effect of N-order MRC diversity reception on the MPSK system is also considered. The results presented are sufficiently general to offer a convenient method to evaluate the perforniance of digital land mobile coherent MPSK systems.
