概要
- 論文の詳細を見る
Diagonally weighted space-time trellis codes using one-bit feedback of channel information are considered. We derive performance criteria for designing STTC and weighting matrix in perfect feedback channel. A simple modification of conventional STTC using unitary rotation is proposed and some modified STTCs are found through computer search. Simulation results show that the modified STTCs achieve the improved performance over a wide range of feedback channel condition.
