In the proposed time-sharing hopped communication method, managing mechanism determines each user channel quality knowledge by controlling the quality of the channels between users and it. In order to present a higher quality transmission for the users with low quality channels, managing mechanism gives an opportunity to them to send their message over the users with high quality channels in time sharing mode. Thus, transmission quality for the users with low quality channel is improved The performance of the proposed receiver, with/without hopping and with cooperative communication technique, is analysed for multipath flat fading channels by computer simulation, and results are presented.trinfo:eu-repo/semantics/closedAccessConference Object450447WOS:000273935600112N/A
