Abstract:It is analyzed that include the function of passenger information system(PIS)and communication based train control(CBTC), as well as wireless LAN IEEE802.11 characteristics and bandwidth requirements implementing intercommunication between PIS and CBTC . Co-channel interference and adjacent channel interference of PIS and CBTC are demonstrated in detail , and the specific solution of the interference problem is given out in the project.
Keywords:CBTC System  PIS System  WLAN  Co-channel interference
