[Invited Paper] Adaptive Configuration of Forward Channels for Terminal Collaborative Reception

抄録

Collaborative reception has been proposed to improve frequency utilization efficiency in wireless networks. This paper proposes adaptive configuration of forward channels that selects not only terminals to forward received signals to the destination terminal but also higher frequency bands for the forward links. We propose adaptive terminal selection algorithms to implement the proposed adaptive configuration of forward channels. The proposed adaptive configuration based on the algorithms achieves higher frequency utilization efficiency than fixed configurations. While the proposed two algorithms attain similar frequency utilization efficiency, one of the algorithms, so called, a complexity-reduced selection algorithm reduces the computational complexity to almost 1/200 of the other of the optimum selection algorithm.
