| Abstract: | This paper focus on the design of Metro TV and PIS system for Beijing subway line 1 and line 2 in the light of engineering specialty of Metro TV and PIS system, the complexity of field environment, and the diversity of functionalities. In view of the inherent limitations and shortcomings of existing PIS transmission system between vehicle and station, this paper discuss the feasibility and benefits of apply- ing train-wayside transmission without transmitter, i. e. DVB-T. |
