ABSTRACT

As one of the key candidate technologies for 5G, D2D communication technology can solve the problem of excessive data traffic caused by excessive number of mobile devices to a certain extent. Aiming at the problem of channel quality deterioration and communication interruption caused by the large distance between D2D communication parties, a relay selection algorithm based on maximum SNR channel prediction is proposed. Firstly, the relay set is established for the correctly decoded relay; Secondly, the channels in the relay set are predicted according to the existing MMSE algorithm, and a set of channel coefficients are obtained to calculate the SNR of each relay link; Finally, the one with the maximum SNR is selected as the optimal relay for forwarding. Simulation results show that the outage probability of the proposed algorithm is about 2 to 3 orders of magnitude lower than that of the random relay selection algorithm.
