Abstract-In this paper, a novel Multi-relay Adaptive Random. Selection (MARS) strategy in a dual-hop multi-relay OFDM sys tem is proposed.
Simulation results show the superiority of the proposed scheme in improving the OFDM system performance in terms of BER by creating a virtual diversity by ...
In this paper, we study the joint allocation of three types of resources, namely, power, subcarriers and relay nodes, in multi-relay assisted dual-hop ...

In this paper, we investigate a novel random selection strategy for dual-hop Single-Carrier Frequency-Domain Equalization (SC-FDE) in cooperative systems with ...
This paper focuses on a joint relay-selection and resource-allocation algorithm for an Amplify-and-Forward (AF) cooperative network. In a multiuser scenario, ...
Mar 15, 2015 · Resource allocation is an important issue that has not been well resolved in multi-relay multi-user Decode-and-Forward (DF) OFDM systems ...
In this paper, we investigate a novel random selection strategy for dual-hop Single-Carrier Frequency-Domain Equalization (SC-FDE) in cooperative systems with ...
In this thesis, we aim to address the challenges of wireless cooperative communications, and design the efficient. OFDM-based relay systems. Starting with the ...
