摘要
文章介绍了第三代移动通信系统地面无线接口技术标准中的Turbo码规范,并详细描述了标准中turbo码的关键参量,如交织器的类型、栅格终止方案、删除复用模式等等。此外,该文还采用3GPP和3GPP2所建议的标准,对turbo码在AWGN信道上传送高速数据业务时的纠错性能分别进行了仿真,并对仿真结果进行了比较。
This paper presents turbo codes proposed by the air interface standard adopted for third generation mobile communication system.Details of turbo interleaver, trellis termination scheme and puncturing pattern as specified in the standards are explained.The performances of turbo codes for high-speed data services over AWGN channel are simulat-ed.Finally, comparisons of BER performances are made between 3GPP and 3GPP2 turbo encoders.
