摘要
Abstract
Turbo code has a very good performance which is close to the Shannon limit.In 1999,CCSDS(Consultative Committee for Space Data systems) has added Turbo code to the recommendation of Telemetry channel coding due to its excellent properties. This paper introduces the coding structure and decoding principle of Turbo codes of CCSDS standard,and studies important parameters which impact its performance,such as block length,iteration number,bit rate,etc.The decoding performances under different parameter condi-tions are simulated by Matlab software.The proposal for parameter selection in deep-space communication system is given based on anal-ysis on simulation results.关键词
