Implementation And Control Of Antenna Combiner Based On DSP

In recent years, counterreconnaissance technology offers new challenges on the battlefieldin the background of the amelioration of the wireless communication technology anddiversification of satellite imaging resolution. and like the military headquarters and otherimportant units of military reconnaissance should be given primary importance among priorities.In the modern military struggle, the examples that the military commander is beheaded and thebattle is failed are very much because of ineffective concealment. Nowadays, the militarycommand center need to use a plurality of antennas to communicate with other headquarters inreal time, how to reduce the number of antennas and ensure the communication quality andcommunication in real time is the key of modern communication research.This topic is designed as antenna combiner with the core of DSP and CPLD formulti-channel signal transmission. TMS320F2812is responsible for implementing orthogonalnetwork and control filter turn-on or turn-off; moreover CPLD see to acquisition and storage ofmultiple serial control word of frequency and TOD. Combiner which is connect with manychannel machine detect communication frequency of communication frequency in real-time anddistinguish priority between them to realize synchronous orthogonal network.Frist This paper introduces the overall design background and idea of system, secondly thetheory design and the actual parameters of the band-pass filter in combiner are discussed in detail,then it tell the hardware design and software design of the DSP system module and CPLDsystem module in the whole system. finally the last part summarize the whole paper and thetarget of the next step work.
