摘　　要：文章对高速载波调制解调技术原理及其实现技术进行研究,并根据MIL-STD-1553A/B实际传输的硬件系统,建立信道模型及噪声模型。该系统由基带信号处理和线缆驱动两部分组成,通过对传输系统中各处理模块的分析,并利用Matlab Simulink仿真平台进行系统级仿真,仿真结果表明OFDM调制解调技术获得10-5较低的误码率,可应用于已有的1553总线这样的高速有线传输系统。In this paper,the high-speed carrier wave modulates and demodulates principles and realization technique was presented,and the channel model and noise model is also established according to MIL-STD-1553A/B actual transmit hardware system.This system included of two parts which were baseband processing and cable driving.By analyzing each processing unit in this transmit system,and simulating system-level based on Matlab Simulink simulation platform,the Simulation result showed that OFDM modulates and demodulates technology low error code rates such as 10-5 could be gotten,so it can be used in high-speed transmit system such as existing 1553 bus system.
