Abstract

Compute-and-forward (CF this method is referred to as “blind C&F” and an algorithm is proposed which guarantees that each relay chooses the best integer vector that contains information from at least m source nodes. In the second algorithm that is described as “partially coordinated C&F,” we assume that partial cooperation between the relay nodes and propose to exchange a single variable with which the relays are sorted for transmission. The performance of the proposed algorithm is nearly equivalent with optimal relaying, which requires significant overhead signaling.
