LTE-A的一种中继选择方案

Relay technology has been extensively concerned in LTE-Advanced system. In this paper, we generalize the category of the relay, and analyze the problem when the relay technology is used in the LTE-Advanced system. we introduce the system module to help analyze the relay selection scheme. Then, to make the least modification for the protocol and reduce the system overhead, this paper advises a new relay selection algorithm. Simulation shows that this scheme can efficiently improve the system performance and decrease the bit error rate.
