Spectrally-Efficient Decode-and-Forward Scheme Based on Constellation Rotation

A spectrally-efficient scheme is proposed for orthogonal decode-and-forward relaying. By utilizing constellation rotation, the scheme can achieve twice the spectral efficiency as that of the conventional one, with low implementation complexity. It can offer a full diversity order as well, whereas the loss in coding gain is less than 1 dB for practical environments.
