Single-Relay Selections with Amplify Forwarding and Network Coding in Two-Way Relay Channels
Hongtao Pan, Chunkai Chen · 2012
In order to overcome the problem of low spectral efficiency in one-way relay network, relay selection problem of the two-way relay channel was investigated. In our research work, single relay-selection strategies with amplify forwarding and network coding in two-way network were proposed. Moreover, bit error rate (BER) and diversity expressions were derived and verified by simulation. Our research results indicated that two strategies can achieve full diversity in the multi-relay wireless network. In the high SNR region, the bit error rate of TWSRS-NC is half of that of TWSRS-AF, and the gain of TWSRS-NC is twice as much as that of TWSRS-AF.
