The frequency compensation to eliminate ICI in CBTC system
IET International Communication Conference on Wireless Mobile & Computing (CCWMC 2009), 2009The CBTC system is an advanced train control system which makes use of big-capacity digital communication between wayside and train, to transfer the information of the status of the train, as well as the controlling information. To prevent accidents which cause severe people injure and finance loss, the information reliability to be guaranteed.

An attempt of using leaky cable at 400MHz in CBTC system
2014 IEEE International Conference on Communiction Problem-solving, 2014This paper introduces a novel train-ground wireless system at 400 MHz based on leaky cable transmission of communication based train control (CBTC) in urban rail transit. Adopting 400MHz band is to avoid the interference of civil equipment at 2.4GHz. Benefited from low frequency band, leaky cable can provide longer transmission distance without relay ...

A Cognitive Control Method for Cost-Efficient CBTC Systems With Smart Grids
IEEE Transactions on Intelligent Transportation Systems, 2017Communication-based train control (CBTC) systems use wireless local area networks for information transmission between trains and wayside equipment. Since inevitable packet delay and drop are introduced in train–wayside communications, information uncertainties in trains' states will lead to unplanned traction/braking demands, as well as waste in ...
