Abstract


BCH code is found so far a good linear error correcting code , and widely used in the field of mobile communications, a radio paging system , and optical fiber communications . 2005 by the Digital Video Broadcasting (DVB) project organization officially released a new generation of broadband satellite applications transmission standard DVB-S2 channel coding scheme using BCH codes and LDPC (LowDensity Parity Check) code cascading . Advanced channel coding scheme combines 16APSK and 32APSK order modulation techniques , so that the DVB-S2 with respect to the DVB-S system capacity increased about 30% . Its excellent performance , state-of-the-art technology , important reference for the future establishment of satellite communication system of the Armed Police Force . The BCH code of DVB-S2, made ??an in-depth study , involved in the DVB-S2, the 21 kinds of BCH codes are four kinds of primitive code of binary BCH code shortening , and the encryption algorithm of the BCH code has been studied , focuses on the BM (Berlekamp-Massey) iterative decoding algorithm and Euclid iterative decoding algorithms and their correction algorithm - BM inverse iterative decoding algorithm and ME (Modify Euclid) algorithm . Secondly, we use the C language in VC 6.0 environment to achieve a variety of software encoding and decoding of the BCH code DVB-S2 , developed on the basis of the simulation software , analog AWGN channel its performance simulation , the simulation results analysis . Finally a DVB-S2 BCH code generic coding circuit and based on inverse BM iterative algorithm decoding circuit design .
