| 摘 要： | 针对列车通信网络日益增长的带宽需求,提出一种TCN基带信号承载高频载波信号的信道共享解决方案,采用OFDM技术与TCN总线共用同一物理介质,在基带传输低速率、高可靠控制指令的同时,叠加更高频域的多媒体数据信息,实现信道复用.利用Matlab建立了列车控制网络宽带OFDM模型,并用FPGA实现了收发机样机系统,最后通过实验,验证了方案的可行性.

| Abstract: | With increasing requirements of bandwidth for Train Communication Network, this paperpresents a channel sharing technical solution. Without adding new lines, we use OFDM technology totransmit additional signals with a higher frequency so as to achieve channel multiplexing. Then webuild a train control network OFDM model by Matlab, and achieve the transceiver prototype system byusing FPGA. Finally the correctness of the model is verified through the experimental results. |
