Abstract(in English) | Terminal cooperative communications is communication in which multiple terminals receive signals transmitted from a base station and transmit them to the receiving terminals at the same time. In terminal cooperative communications, the optimum relay terminal is selected by considering the status of multiple relay terminals. We propose the optimum terminal selection method for selective communication. In the proposed method, all the weights of the base station, the relay terminal, and the receiving terminal are considered and multiplied. First, the Doppler frequency of the relay terminal is estimated. The SNR of each relay terminal is obtained using the estimated Doppler frequency, and the optimum relay terminal is selected by comparison. This makes it possible to select the most suitable terminal assuming an environment in which the relay terminal is moving at high speed. When the characteristics of the proposed method were evaluated by computer simulation, it was possible to obtain communication characteristics that did not deteriorate even when the relay terminals moved at high speed in terminal cooperative communications using three relay terminals. |
