| Abstract: | In order to solve the problem of relay cooperation transmission mechanism which applied in cells , this paper improved a R-PNC cooperation transmission mechanism. By taking NC-DF, NC-AF and R-PNC into relay cooperation communication of cells, improving above three kinds of relay transmission protocols and analyzing different relay states of different slots, adopted Markov to establish transfer model of relay transmission state and derived up-link normalized network throughput formula of three kinds of cooperation transmission mechanisms. The simulation results show, comparing with traditional relay forward mechanism, all above cooperation transmission mechanism can enhance the throughput in cells, and R-PNC transmission mechanism is the best of all. |
