摘要
对接触网感应式扩频通信系统进行研究。介绍接触网感应式扩频通信系统的组成,建立扩频通信的仿真试验环境,在接收端采用联合解扩和解调的方法,对不同信道及不同信噪比下的系统传输性能进行仿真,并给出仿真结果。
The research on the inductive spread spectrum communication system of catenary is conducted and the constitution of the system is introduced. Through setting up the simulation environment of spread spectrum communication and adopting the united method of dispreading and demodulation, the transmission performance of the system is simulated under different channels and different signal noise ratios (SNR) and the simulation result is concluded.
