【Abstract】 The soft judgment decoding which improves the features of short wave channels is elaborated. Several less complicated practical soft judgment decoding schemes are given. The results of several schemes applied in short wave channels of different error features are also evaluated. The results expatiate that the soft judgment technology decreases 2.5 times as much as the average output error-coding rate of short wave channels.更多还原
