This paper proposes a new multiuser communication model in which a source with
broadcast capabilities wants to transmit two different messages to two different destinations …

In this paper, we consider the transmission over multiple access relay channel (MARC) in
which the relay operates in half‐duplex mode. The main contribution of this paper is …

In this paper, the Half-Duplex Relay Channel (HDRC) is thoroughly investigated. Even
though this channel model is widely studied, the capacity is not yet fully understood and …

This paper introduces a new multiuser communication model, which we call multiple access
diamond channel. In this channel model, many sources transmit their signals to a destination …

In this work, we investigate the Gaussian multiple-input multiple-output (MIMO) half-duplex
relay channel. We firstly propose a two-phase transmission scheme which helps us in …

This study considers the Gaussian cognitive interference channel (IC), in which one of the
two users operates in cognitive mode. In addition, to transmit its signal, the cognitive sender …
