Ergodic mutual information of OFDMA-based Selection-Decode-and-Forward cooperative relay networks with imperfect CSI

This paper presents a novel approach to investigate ergodic mutual information of OFDMA Selection-Decode-and-Forward (SDF) cooperative relay networks with imperfect channel state information (CSI). Relay stations are either dedicated or non-dedicated (i.e., subscriber stations assisting other subscriber stations). The CSI imperfection is modeled as an additive random variable with known statist...

MIMO DF Relay Beamforming for Secrecy with Artificial Noise, Imperfect CSI, and Finite-Alphabet

In this paper, we consider decode-and-forward (DF) relay beamforming with imperfect channel state information (CSI), cooperative artificial noise (AN) injection, and finitealphabet input in the presence of an user and J non-colluding eavesdroppers. The communication between the source and the user is aided by a multiple-input-multiple-output (MIMO) DF relay. We use the fact that a wiretap code ...

On the MIMO Capacity with Imperfect CSI

Multiple-input multiple-output (MIMO) antenna systems provide high capacity gain over a single-antenna system. This gain is maximised when channel state information (CSI) is available at the transmitter. In practice, however, only partial information could be obtained. In this paper, we shall present a study of the MIMO system capacity in the case of imperfect CSI. It is found that in the case ...

MIMO-THP System with Imperfect CSI

In recent years, it was realized that designing wireless digital communication systems to more efficiently exploit the spatial domain of the transmission medium, allows for a significant increase of spectral efficiency. These systems, in general case, are known as Multiple Input Multiple Output (MIMO) systems and have received considerable attention of researchers and commercial companies due t...

Joint Cooperative Relay and Cross Layer HARQ

Wireless Sensor Networks (WSN) has drawn significant attention recently as a key important factor especially in sensitive areas, through which, data can be simply collected and transmitted. However, we lack practical WSN that promises a high-speed, real time and energy efficient communication with a small size cell battery. In this paper, we proposed a novel cross-layer Hybrid Automatic Repeat ...
