Channel-optimised Vector Trellis Source Coding for the AWGN Channel
Philip Secker, Philip Ogunbona · International Symposium on Information Theory and its Applications · 1994
A channel-optimised (joint source and channel) trellis source coder is designed for the AWGN channel. The optimum decoder is a non-linear function of the real channel information. The extension to 2D vector alphabets coupled with modifications to the signal space are found to improve performance. Favourable comparisons are made against a trellis source coder/TCM system.
