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了研究,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 MILSTD-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.
