The information transmission problem in a class of wireless multi-user single-antenna half-duplex relay interference networks is studied. In these networks there are multiple clusters of sources. All the terminals in each source cluster desire to transmit independent messages to a single destination, through multiple layers of intermediate half-duplex relays. We adopt a cluster successive relaying...
The performances of multihop parallel free-space optical (FSO) cooperative communication systems with decode-and-forward protocol under exponentiated Weibull (EW) fading channels have been investigated systematically. With the max–min criterion as the best path selection scheme, the probability density function and the cumulative distribution function of the max–min EW random variable are derived...
In recent years, the MIMO-based underwater acoustic (UWA) wireless sensor networks have attracted significant research attention because of its wide and critical applications in marine research, oceanography, marine commercial operations, offshore oil industry, and defense systems. The cooperativecommunications- based wireless relay networks have been widely cited as a very efficient technique to...
The next generation network with high data rate and large coverage is demanded. In the cellular network, the enhanced MIMO-OFDMA relaying technology has become one of the most promising solutions. In a relay-enhanced cellular, multiple Relay Stations (RSs) are deployed to assist transmissions between a Base Station (BS) and multiple Mobile Stations (MSs). However, the resource allocation becomes more...
Multi-path fading, one of the key factors that deteriorate quality of service (QOS) in Underwater Acoustic Networks (UANs), is investigated under different underwater scenarios in this paper. To improve the Bit Error Rate (BER) performance, the techniques of cooperative diversities are applied. Considering realistic physical model and cooperative diversity techniques, two asynchronous forwarding schemes,...
Relay transmission or cooperative communication is an advanced technique that can improve the performance of data transmission among wireless nodes. However, while the performance (e.g., throughput) of a source node can be improved through cooperation with a number of relays, this improvement comes at the expense of a degraded performance for the relay nodes due to the resources that they dedicate...
For designing a wireless network, field test is mostly preferred for researchers to test and evaluate the system performance. However, it is expensive for field constructions and thus it is not affordable for most researchers. Software simulation is another option. However, the results by simulation may be undesirably biased away the true. This paper proposes a new method to trade off between resource...
