Abstract

In this paper, we propose a new transmission scheme for railway wireless communication. By realizing single frequency network based on OFDM, we improved the performance of GSM-R by realizing "soft handover" . And in order to improve our system\´ s performance in frequency selective multipath channel, we adopt generalized Multi-Carrier-CDMA (GMC-CDMA) scheme to optimize our system. Relying on symbol blocking and judicious design of user\´ s code, GMC CDMA could obtain a better interference resilient performance in multipath fading channel while guaranteeing a good symbol recovery.
