Secrecy in Cooperative Relay Broadcast Channels
We investigate the effects of user cooperation on the secrecy of broadcast channels by considering a cooperative relay broadcast channel. We show that user cooperation can increase...

Adaptive multidimensional coded modulation over flat fading channels
We introduce a general adaptive coding scheme for Nakagami multipath fading channels. An instance of the coding scheme utilizes a set of 2 -dimensional (2 -D) trellis codes origina...

Code design for MIMO downlink with imperfect CSIT
—In this letter, we implement a simplified version of the Cover - van der Meulen - Hajek - Pursley (CMHP) coding originally characterized by Wajcer, Wiesel, and Shamai. The vect...

A simple baseband transmission scheme for power line channels
We propose a simple pulse-amplitude modulation (PAM)-based coded modulation scheme that overcomes two major constraints of power line channels, viz., severe insertion-loss and impu...

Rate Bounds for MIMO Relay Channels Using Message Splitting
This paper considers the multi-input multi-output (MIMO) relay channel where multiple antennas are employed by each terminal. Compared to single-input singleoutput (SISO) relay ch...
