Application of Vandermonde Binary Array Code in Embedded System

For Vandermonde binary array code algorithm ,this paper describes the encoding/decoding process of the erasure code, focuses on encoding and decoding algorithms of Vandermonde code, and proposes a fast algorithm applicable to the implementation in embedded system. Since Digital Video Broadcasting-Satellite （DVB-S）system model is established and the channel code error distribution is simulated in Matlab, thus the error code distribution of DVB-S system is obtained, and the feasibility of Vandermonde erasure code in the system is analyzed. Furthermore, the paper proposes the cascade model of erasure code and error correction code in DVB-S and simulates the error correction performance of the algorithm. The simulation results indicate that the cascade model can improve the reliability of wireless transmission system considerably.
