摘要
针对机载图像传输系统的特殊性,结合机载设备现状,提出了一种图像传输方案,对其中的关键技术——正交频分复用进行了分析,并对正交频分复用系统的参数选择进行了讨论。
The present paper proposes an image transmission scheme base on Orthogonal Frequency Division Multiplexing （OFDM） technique which is integrated with the spread spectrum interface of the transceiver for a certain type of aircraft. OFDM is a robust technique in fading environment and is adopted to improve spectrum efficiency in the scheme, parameter selection for an OFDM system is discussed.
