摘要
工作在电话网上的高速调制解调器 (MODEM)应用十分广泛 ,壳状映射技术是使MODEM性能得以改善的关键技术之一 .论文对高速调制解调器中的壳状映射技术进行了详细的分析 。
High speed modems are widely used in telecommunications networks. Shell mapping is one of the most important techniques to improve the performance of a modem. In this paper, shell mapping technique is analyzed in detail, and an algorithm is given to achieve mapping at the encoder and demapping at the decoder.
