Random access strategies have been applied to various wireless systems for a long time. Recently, the fast retrial algorithm has been proposed to improve the performance of random access in orthogonal frequency-division multiple access (OFDMA) system. This paper studies the performance of the OFDMA system with the fast retrial algorithm when the number of(More)
The fast retrial random access (FRRA) algorithm has been recently proposed for orthogonal frequency-division multiple access (OFDMA) uplink channels to improve the performance by taking advantage of multiple channels in the frequency domain. In this paper, we study the impact of channel outage on the throughput of FRRA algorithm through extended performance(More)
