Spectral efficiency loss due to the half-duplex operated in relay nodes can be potentially improved by the two-path relaying(TPR)protocol.However,the mutual interference between the relay nodes can negatively affect the performance.Therefore,relay selection can be crucial to the system performance.In this paper,we propose a heuristic relay selection method for the decode-and-forward TPR strategy in order to maximize the transmission rate.Different from the existing relay selection methods,the inter-relay interference is considered.Meanwhile,the design principle of this method is based on not only the link conditions in current time slot,but also those of the relay node selected in previous time slot.Simulation results are conducted to verify the effectiveness of the proposed heuristic relay selection scheme.
