Abstract
The paper considers a source-relay-destination link in which the relay node is allowed to reassign the input subchannels to different output subchannels. In particular, we consider a channel-aware relay node and compute the subchannel reassignment that optimizes a selected performance criterion. The numerical results suggest that optimized subchannel reassignment is particularly beneficial in frequency-selective channels and in channels where interference information is available at transmitter.
