Expectation Propagation for Flat-Fading Channels

Abstract: This letter addresses the problem of signal detection in flat-fading channels. In this context, receivers based on the expectation propagation framework appear to be very promising although presenting some critical issues. We develop a new algorithm based on this framework where, unlike previous works, convergence is achieved after a single forwardbackward pass, without additional inner detector iterations. The proposed message scheduling, together with novel adjustments of the approximating distributions' par… Show more

“…where T S is the sampling period and it is assumed that 1/T S equals the system bandwidth B. η is a factor that is the proportion of the transmission phase for duty cycle. Note that η ≈ 1, the overhead from the recording phase in TR process can be neglected when the fading channel is assumed as flat fading [15].…”
