摘要
Abstract
As the traditional MIL-STD-1553B cannot meet the demand for high-speed data transmission and replacing the existing data bus can be cost prohibitive, there is an urgent need to upgrade the 1SS3B system to offer high-speed communication interface without interfering the existing baseband communication. This paper analyzes the characteristics of the channel in 1S53B and selects the discrete multi-tone modulation ( DMT) as the technology of extending the bandwidth of 1553B for its high spectrum efficiency. A scheme of upgrading 1553 B compatible with the existing system based on discrete multi-tone modulation is proposed and the key technologies involved in the scheme are discussed.关键词
