A system for selective relay in an LLR based ad-hoc network using energy allocation is provided to retransmit relay based on LLR considering paging and noise, thereby improving reliability and performance of retransmission. A source(S)(110) simultaneously transmits a signal(a) to a relay(R)(120) and a destination(D)(130) during the first phase time. The relay and destination receive the signal transmitted from the source. When an LLR(Log-Likelihood Rate) value of the signal received from the source is greater than a reference threshold value, the relay transmits a demodulated signal with regard to the signal to the destination. An energy allocation unit(140) allocates energy to the source and relay respectively. |
