| Abstract: | To discuss the problem of train's information interrupt when handovers occur in railway mobile communication system-GSM-R nowadays,a research is carried out on the performance of handovers in the railway mobile synchronous communication net with single frequency cell(OFDM-SFCNR) which is based on OFDM-SFCN(orthogonal frequency division multiplexing-single frequency cell network).Experiment suggests that,compared with GSM-R,OFDM-SFCNR can not only reduce the times of train's communication data interrupt,but ... |
