Symbol error rate for Ricean fading channel with random K parameter

In this paper we analyze symbol error probability of a digital communication system over wireless fading channel, where the random signal envelope fluctuations are described with Ricean fading distribution. Instead of considering only the envelope, i.e. instantaneous signal-to-noise ratio (SNR) as a random variable, whereas Ricean K factor is deterministic parameter, we examine implications and insights that can be drawn from assuming a fading channel environment characterized with a random Ricean K factor. A novel moment generating function (MGF) of a such new distribution is derived and average symbol error rate (SER) for single and multi-channel receptions are obtained.
