Abstract: A method is described for processing a signal at a relay node in a wireless communication system. More specifically, in one embodiment, the relay node receives a codeword broadcast from a source node. The codeword is partitioned into a plurality of sub-blocks. Then, the relay node generates two network encoded codewords by combining linearly the plurality of sub-blocks, and transmits the two network encoded codewords to a destination node. The destination node detects the codeword by using a zero-forcing receiver.
