Abstract :
In this paper, a scheme of signal space diversity based on non-binary LDPC codes is presented. Signal space diversity can provide good performance gains over fading channels with multi-dimension rotated constellation. This paper studies the extension of such schemes with a non-binary code. It is shown that non-binary LDPC-coded modulation with signal space diversity over a fading channel may lead to a significant gain over the convolutional code or conventional unrotated constellation.
