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.
