摘　　要：为了提高无线信道频谱利用率I,ETF提出了ROHC(robustheader compression)信头压缩协议。介绍ROHC基本原理、模式和状态转移逻辑,给出了W-LSB压缩解压算法,实现了算法中的主要函数,并利用SDL对ROHC协议进行建模,最后对ROHC协议进行了性能分析和展望。ROHC is a header compression protocol proposed by IETF, which can be used to save wireless bandwidth. The basic ROHC principle and the transition logic of ROHC mode and state are briefly introduced. The W-LSB compress and decompress algorithm is deeply studied and the main functions in this algorithm is realized. The ROHC is modeled with SDL language. Last the performance analysis and the prospect of ROHC protocol are given.
