two kinds of out-of-band relaying methods were pro-posed to improve the conventional CDMA cellular systems.Then by analyzing the interference power of the non-relaying CDMA cellular systems
the overall interference power to own and neighbor cell could be obtained with using these two relaying methods.Finally
based on a symmetrical cell model
the uplink capacity of two-hop-relay CDMA cellular sys-tems was analyzed by mathematical calculating
and the impact of these two relaying methods on system’s performance was discussed.
