A high-efficient coded cooperative(CC) scheme with high-order constellations is proposed.In this scheme,encoded bits of the user or the partner are partitioned,bit interleaved,mapped on a high-order two-dimentional constellation and then transmitted on the allocated time slots.The pairwire error probability over slow-fading Rayleigh channels are derived.Both theoretical analysis and simulations show that the coded cooperation with high-order constellations can achieve full diversity with an improved spectrum effciency over slow-fading Rayleigh channels.
