In this paper, we study the joint transmitter and receiver design problem over frequency-selective fading channels. Motivated by a conventional minimum mean square error decision feedback equalizer (MMSE-DFE), we present a simple approximate maximum-likelihood (ML) decision feedback equalizer at the receiver. We then perform precoding in a downlink scenario at the transmitter side to minimize the...
In this paper, we propose a serial signal detector (SSD) for time-reversal space-time block codes to combat intersymbol interference in frequency-selective fading environments. In order to achieve single symbol detection, we consider the effects (covariance) of the undetected signals instead of treating them as noise and use the already-detected symbols to help current signal recovery. Simulations...
