The application of finite automata in CMMB data-demultiplex error handling

Through analysis the multiply frame structure of China Mobile Multimedia Broadcasting (CMMB) system, design a method of the terminal data-demultiplex error handing., using finite automata principle, proposed a method to solve a problem caused by error data stream for terminal demultiplex process. This method classified the error data-code stream which was received by terminal, summarized some states for all kinds error data-code stream, and gave all sorts of conversion conditions between different states, designed a finite automata. After achieved by C code, it is not only to see the finite Automata can good deal with the error data-code stream received by terminal, but also it can reduce the complexity when system carries on error processing. And it is very easy to upgrade the system.
