Multiple-input multiple-output (MIMO) systems exploit transmit diversity to combat the effect of fading channels. Recently, a new paradigm known as cooperative communication was proposed that achieves the same transmit diversity as the MIMO system. However unlikely MIMO system which requires multiple antennas, cooperative communications use the scheme of sharing single antenna to generate a virtual...
Cooperative communication represents a new class of diversity techniques in which multiple nodes each with a single antenna cooperate to generate a virtual multiple-antenna transmission system and thus offer the benefits of spatial diversity. This paper proposes suitable array codes used as low-density parity-check (LDPC) codes to be applied in the cooperative amplify-and-forward (AF) network. A mathematical...
