Abstract:

Considering the characteristics of heterogeneous cooperative relay channel, the uplink and downlink relay channel models are presented. Analysis on the capacity of the heterogeneous cooperative relay channel is given, and compared with homogenous cooperative relay channel, in order to elaborate the advantages and disadvantages of the two different relay channels, as well as the applicable scene. A numerical example is given to describe how the power distribution and the location of the relay impact on the capacity of the relay channel. The differences between the two different relay channels are analyzed.

Key words: heterogeneous relay, homogeneous relay, cooperative relay, channel capacity
