Relations between Rice Ie-function and Marcum Q-function with applications to error rate calculations

Useful relations connecting the Rice Ie-function and the Marcum Q-function are presented. A function P(U,V), closely related to the Ie-function, is applied to bit and symbol error probability calculations and shown to lead to expressions that are simpler and more elegant than corresponding results written in terms of the Q-function.
