Instruction image wireless transmission system and method of frequency division multiple access and time division multiple access mixed system

Abstract

The invention provides an instruction image wireless transmission system and method of a frequency division multiple access and time division multiple access mixed system. Instruction data is transmitted through adoption of a time division multiple access system at an uplink, and image data is transmitted through adoption of a frequency division multiple access system at a downlink. An uplink signal processing module processes the instruction data to form a way of uplink transmitting signals. The uplink transmitting signals are sent to a downlink signal processing module through a transmittingchannel of an uplink radio frequency module and a receiving channel of a downlink radio frequency module in turn. The downlink signal processing module processes a plurality of ways of image data toform a plurality of ways of downlink transmitting signals. The downlink transmitting signals are sent to the uplink signal processing module through the transmitting channel of the downlink radio frequency module and the receiving channel of the uplink radio frequency module in turn. According to the system and the method, an asymmetric system is employed, namely, the time division multiple accesssystem is employed at the uplink, and the frequency division multiple access system is employed at the downlink, so parallel transmission of a plurality of ways of instruction data and image data isrealized.

Description

technical field [0001] The invention relates to wireless communication transmission of data and images, in particular to a command image wireless transmission system and method of a frequency division multiple access and time division multiple access hybrid system. Background technique [0002] At present, the command image wireless transmission system is used for data and image wireless information transmission during the flight of missiles or UAVs. [0003] At present, the general data and image wireless transmission system on the market adopts time division multiple access to transmit command data and image data, which can only realize single-channel data and image transmission, and multiple sets of equipment are required for wireless transmission of multiple target images at the same time Working together, the system cost is expensive, the volume is large, the power consumption is large, and the cooperative control is difficult.
