| 摘 要： | 讨论了采用格栅编码的离散多频音调制（ＤＭＴ）系统，并推导出了编码增益的具体计算方法。该系统可获得３～６ｄＢ的编码增益，等效于降时误码率或传送距离更远。

| Abstract: | Discrete multitone modulation system using trellis codes is studied. A calculation method in coding gain is proposed. 3 to 6 dB coding gain can be obtained in the proposed system which is equivalent to either reduction of bit error rate or increase of transmission distance. |
