Research and implementation of high-speed aviation bus

Since traditional aviation bus gradually can not meet the needs of modern military communication, migration of aviation bus towards high speed transmission is arousing wide concern. This paper purposes a method for improving throughput and transmission rate of the aviation bus while reserving legacy devices. In addition to cost, the logistics of implementing this upgrade to an aircraft can be prohibitive based on the amount of time required to retrofit an entire fleet. Moreover, the method combines OFDM (Orthogonal Frequency Division Multiplexing) modulation and aviation network has been evaluated over MIL-STD-1553 bus. The maximum rate can achieve 22 Mbit/s. It shows a considerable performance improvement and meets the requirements of avionic high-rate communication.
