In this paper we have investigated the optimum power allocation in a random access wireless orthogonal frequency division multiple access (OFDMA) communication system with multiple source and multiple destination nodes. The multiple sources in the system each transmitted information to multiple destinations and cooperated via an orthogonal regenerative decode and forward protocol with different frequency...
In this paper, we study the sum throughput maximization with access proportional fairness (APF) for downlink orthogonal frequency-division multiple access (OFDMA) channels. We propose selective multiuser diversity (SMuD) schemes with normalized signal-to-noise ratio (n-SNR)-based ranking for user selection at each carrier to achieve long-term fairness. We also propose a modified absolute signal-to-noise...
