In this paper, a decentralized wireless network based on OFDMA with multiuser diversity allocation has been modelled and simulated.
Abstract— In this paper, a decentralized wireless network based on OFDMA with multiuser diversity allocation has been modelled and simulated.
In this study, we consider a single-hop wireless sensor network where both the sensor nodes and the controller node have multiple antennas.
If the users in the distributed system use power allocation when they transmit, then by a similar argument as in. Appendix L it can be shown that. i.e., this ...
Abstract. In wireless fading channels, multiuser diversity can be exploited by scheduling users so that they transmit when their channel conditions are ...
Decentralized multiple access networks require dynamic spectrum allocation to efficiently and fairly allocate resources among multiple users.

tic access scheme for uplink OFDMA systems. The sub-carriers are grouped into several sub-channels. Users access these sub- channels through a distributed ...
In this article, we propose an innovative and efficient distributed spectrum allocation algorithm, whose objective is to maximize the system UL capacity by ...
Multiuser systems can provide multiuser diversity gains by assigning channels to users with higher channel gains. To avoid the extensive information ...
Abstract-Orthogonal frequency division multiple access (OFDMA) is a popular and widely accepted multiple access technique to provide high data rate.
