A Research On The Algorithm About The Coding And Decoding Of The RS Codes In The Deep Space Communication

This work mainly investigates the RS codes in the deep space communication. Firstly, we introduce the basic theory of the coding and decoding of the channel which describe the possibility of the errorless transmission in the channel existing interference. It is the foundation theory and heading aspect of the correct coding ;then we introduce some correlative algebraic definitions, theorems and some familiar codes in brief, stressing importance to discussing the algorithm of the time field coding and decoding . In this paper, it analyses the realization process of the RS code with certain parameter. Contemporarily we set up felicity channel model to simulate and to analyse the performance of the correct RS codes. Advancedly we bring forward the coding and decoding method in the frequency field upon RS codes. In the third part it introduces the convoluted and Turbo code simply and at the last part of the paper, we introduce the speciality of the deep space channel and compare the used coding and decoding system in the foreign countries, then we bring forward the scheme which our working group will adopt.
