WiMAX系统基于CID的压缩机制研究
摘要
分析了WiMAX系统分段MAC PDU报头及子头格式
提出了一种利用分段MAC PDU头保留位和子头保留位对CID进行编码的压缩算法
实现对分类之后冗余信息的有效压缩
给出了详细的算法流程
并对无线信道模型和CID映射表进行了量化分析。仿真结果表明
提出的压缩机制达到了满意的压缩效果。
Abstract
The format of sub-MAC PDU’s header and sub-header was analyzed in WiMAX system.And a compression algorithm was proposed
which encoding CID using reserved bits of the sub-MAC PDU’s header and sub-header
thus redundant information was compressed efficiently after information classification.Algorithm flow was introduced in de-tails
radio channel and CID mapping table were analyzed quantitatively.The simulation results show that the proposed compression mechanism achieves satisfactory compression effect.
