|
In Communication Based Train control handoff latency is a challenging factor in wireless technology.In this paper handoff latency is reduced by make before break scheme.By this scheme signal detected without multiple radio transceiver at Mobile Station instead two antennas are used one at front end and other at back end which connects with new and old access point respectively. Information about train is sent inSpace Time Block Code through which interference is cancelled. With Multiple Input Multiple Output Maximum Ratio Combining Signal to Noise Ratio is increased.The channel is estimated using Mean Square Error and Bit Error Rate and distance between two APs are calculated.The information about train is encrypted to protect from hackers using Advanced Encryption Standard algorithm.The result shows that using MIMO can significantly reduce handoff latency for CBTC services |
