Abstract :
This paper proposes a kind of security radio data transmission mode based on turbo codes for communication based train control (CBTC) system in urban mass transit, and presents the simulation and analysis with several different decoding algorithms in this paper, such as Bi-SOVA, SOVA, MAP and Max-Log-MAP. The results show that Bi-SOVA algorithm and max-log-MAP algorithm have better performance of bit error. Therefore, it is reasonable and effective to use turbo codes for replacing traditional CRC for error-correction in security radio data transmission of CBTC system.
