Many statistical models are available for the non-line-of-sight flat-fading wireless communication channel. It is of great interest to evaluate performance bounds of wireless communication systems whose channel statistics cannot be modeled with certainty. In the past, we have proposed a unified theory for modeling the non-line-of-sight flat-fading channel envelopes based on the spherically invariant random processes (SIRP). We have also advocated the use of moment-bound theory to obtain bounds on these performance metrics. However, these bounds may be very loose when only limited prior knowledge of the channel is available, typically in the form of moments and of the type of probability distribution of the channel fading. In this seminar, we combine the theory of moment bounds with that of SIRP, and use semi-definite programming (SDP) to show how sharper bounds of the error rate of a communication system can be computed.
