Opportunistic scheduling and spectrum reuse in cellular networks based on a diversity of relay

Due to the increasing need for high-rate service and maintain the quality of service in wireless networks, wireless telecommunications world is now moving into the fourth generation of the third generation.Contacts fourth-generation wireless communication system requires a maximum of efficiency. In order to develop strategies to increase the efficiency of payment that requires analysis of opportunistic scheduling and spectrum reuse in cellular networks based on a diversity of relay.One of the devastating effects of wireless communication systems is fading. To address the problem of diversity uses. Fade the diversity of ways of coping with adverse effects and improve the performance of the system.In line with the diversity and multi-system planning and optimize spectrum reuse in relay-based cellular networks has been tried that in this paper analyzes the spectral efficiency performance in a multi-channel to be dealt The results stated that the procedure was done very good performance even with a small number of users in the Fade is Riley. Orthogonality between sub-channels in frequency relays operate based on the frequency of the source and relay.
