摘要
联合信源信道编码技术在变信道下的传输速率可接近理论极限,因此在未来多媒体通信中有很好的应用前景。本文介绍了当前联合信源信道编码技术,包括不等错误保护、信源信道直接映射机制和联合译码等。
Joint source-channel coding (JSCC), which can approach the theoretical limit of transmission rates with varying channels, has a splendid application future in multimedia services. In this paper, the JSCC technology including unequal error protection, direct source-channel mapping scheme, joint decoding and so on is introduced.
