The invention provides a TDD high-speed image transmission system, a communication control method and a working method. The TDD high-speed image transmission system adopts the modularization hardware structure design, is small in size, high in integration density and multifunctional, and can achieve high-performance and high-speed data signal transmission. The TDD high-speed image transmission system integrates high-quality images (comprising videos and pictures) and other data services, and transmits data information and video image information in real time according to a specific message format and communication format; a transmitter-receiver has TDD two-way communication ability, and the same set of equipment supports the down-load of videos (visible light and infrared), pictures and SAR signals, and also supports the up-load of low-speed data services such as reverse measurement and control data; spectral efficiency is high, and therefore the requirement for the present aerospace communication which is changed quickly is met.
Description
technical field [0001] The invention relates to a high-speed image transmission system, a communication control method and a working method, in particular to a TDD-based high-speed image transmission system, a communication control method and a working method. Background technique [0002] The two-way transmission of image, voice and data services is the key technology of the high-speed video transmission communication system (hereinafter referred to as the video transmission system). Most of the existing video transmission systems only support one-way video data stream transmission, or rely on Frequency Division Duplexing (FDD) to meet the needs of integrated communication services. This type of image transmission system has complex hardware, high cost, and low spectrum utilization. [0003] In terms of IF signal processing hardware architecture design, the traditional image transmission system adopts the combination of FPGA+DSP+MCU. figure 1 It is an intermediate frequen...
