摘要
在分析Turbo码结构和原理的基础上,介绍了Inmarsat M4和Inmarsat F系统中实现"压缩频带的高速数据(HSD)传输"的核心技术。着重阐述Turbo码多电平调制结合方式、信道状态信息提取、译码算法和实现上有待解决的关键问题。
In the paper,we first analyze the structures and principles of Turbo encoder and decoder.The kernel technique of 'high speed data transmission in reduced bandwidth'in InmarsatM4 and InmarsatF is introduced.Then,we discuss the Turbo encode and decode technique applied in Inmarsat system,and some problems are proposed to be solved finally.
