摘要
结合MFSK调制和卷积编码,提出多音网格编码调制方案。该方案可保证频带宽度和符号速率同未编码的MFSK系统一样。最后从编码增益和频带有效性角度对该方案的性能作了评价。
A scheme of multi-tone trellis-coded-modulation(MT-TCM), which combines the convolutional encoder and MFSK modulation as an entity, is proposed. The scheme can keep frequency bandwidth and symbol rate as the uncoded MFSK system.Lastly, the performance of the scheme is given in terms of the asymptotic coding gain as well as bandwidth efficiency.
