Research Abstract |
The objective of this study is to clarify the channel capacity of multi-channel wireless communication systems which use relay techniques to expand the reachable area from a sender. Toward the objective, we consider optimal power allocation to each channel of the multi-channel system. As the relay techniques, we propose a simple amplify-and-forward relay, a channel switching method according to the quality of each channel state, and a switching method of chunk of channels based on the channel state information. As the result, we proposed corresponding optimal power allocation methods to each relay technique and derived channel capacities.
