摘要

This study introduces a wireless scheme to solve the coverage problem in carriages of Chinese High Speed Railway (CRH) trains. In the proposed scheme, digital TV programs can be retransmitted by CMMB (China Mobile Multimedia Broadcasting) transmitters after being transmitted from the base stations to the trains. The in-car channel profile is analyzed and presented. And the modified linear minimum mean-square error (LMMSE) algorithm proposed by Zheng is adopted to estimate the channel in the CMMB receiver with 2MHz bandwidth. Simulation shows that the CMMB receiver has good reception performance and the proposed broadcasting coverage scheme is feasible.
