Iterative Detection Techniques for Clipped OFDM Systems
—This paper studies orthogonal frequency-division multiplexing (OFDM) systems employing coded modulation. Clipping is applied to reduce the peak-to-average-power-ratio (PAPR) of ...

Distributed Space-Time-Frequency Block Codes for Multiple-Access-Channel with Relaying
—In this paper, we investigate diversity gain in coding for a 2-user multiple-access-channel (MAC) with cooperating transmitters–the MAC with relaying. We propose a simple dist...
