Abstract
The invention discloses the multi element combinatino method in the dual frequency channels of wireless transmit receive belonging to the area of the telephone communication technique. The invented method can be utilized in such wireless system that the n dual frequency channels works at UHF or VHF and meets the original normal technical requirements as well as the channels fully present can be selected arbitrarily. The receiving frequencies are Ri, i=1,2,3...n, the relevant frequencies are Tj, j=1,2,3...n. The dual frequency channels combined by Ri and Tj can be expressed by the complex matrix element Cij=Ri+kTj. The wireless system contains all n2 available dual frequency channels [Cij]nXn. The invention increases the capabilities: anti-interference of voice, anti-interception and anti-embezzelement of the system.
Description
Technical field
The invention belongs to the telephone communication technology, particularly a kind of radio receiving and transmitting double frequency channel multi-component combination method is applicable to and in superfrequency, very high frequency(VHF) radio communication or out of Memory transmission technology receiving and transmitting double frequency is carried out polynary combination and constitutes channel group.
Technical background
At present, superfrequency or very high frequency(VHF) wireless communication system are used in many enterprises and institutions and industry department as the communication private network, ubiquitous system generally is made of and networking transceiver, connector, radio station or hand-held set, with realize wireless and wired between, information communication between wireless and wireless is got in touch with and transmit.In actual applications, because a reception frequency and an emission frequency are combined into a double frequency channel, combination of its transmitting-receiving frequency is single and fixing, is a kind of wire combination, and its transmitting-receiving frequency difference is a segmentation unanimity and known.So, will there be following shortcoming: the one, in double frequency channel, as long as search a frequency, just can know pairing another frequency of this frequency by inference, thereby be easy to by two-way eavesdropping of all channel or active jamming; The 2nd, the number of forming available double frequency channel only is half of used transmitting-receiving frequency sum, so the frequency utilization ratio is not high, the combination of frequency operational version is underaction also.
Summary of the invention
A kind of radio receiving and transmitting double frequency channel multi-component combination method that the purpose of this invention is to provide novelty, practicality, overcome the above-mentioned shortcoming and defect of prior art, to improve the ability of anti-active jamming of wireless communication system and debug, improve the utilization ratio of wireless communication system working frequency points and use flexibility.
The technology of the present invention solution can reach above-mentioned purpose: a kind of radio receiving and transmitting double frequency channel multi-component combination method, work in superfrequency or very high frequency band at n double frequency channel, and satisfy the former normal specification requirement of system, and capacity presets in the wireless system that channel can be selected for use arbitrarily, and base station uses and receives frequency and be R

The present invention compares with the original system technology, and following advantage is arranged: use the present invention and can make the wire combination of wireless channel transmitting-receiving frequency become planar combination, thereby maximum available double frequency channel number is increased to n by n
2, the assembled scheme of the frequency of forming wireless double frequency channel is planted by a kind of n of being increased to (n-1).The present invention is with all transmitting-receiving frequencies of wireless system, no longer treat by the isolated channel concept of original technology, but manage as a total system of information flow, from this point, use transmitting-receiving frequency and spectrum allocation may that the present invention does not change wireless system, but the channel of forming has been different from the channel of original notion.Because the combination of transmitting-receiving frequency and the flexibility of selecting and the not intellectual of channel transceiver frequency difference make the anti-active jamming of system, resist the ability that conversation is intercepted and anti-channel is usurped to be improved significantly, and the function of system organization communication is further expanded.The scope of application of the present invention is wider, and in very high frequency(VHF) or superfrequency radio communication private network, the popularization investment seldom, application is convenient, effect is obvious; The present invention has good economic benefit and social benefit.
Embodiment
Specific implementation method of the present invention and embodiment are as follows: a kind of radio receiving and transmitting double frequency channel multi-component combination method, n the double frequency channel that is applicable to wireless system works in superfrequency or very high frequency band, and satisfy the former normal specification requirement of system, so that the excursion of channel transceiver frequency difference is limited to the basic using property data of the system of not influencing, the channel that presets more than the operation channel can be selected for use arbitrarily, and base station uses the reception frequency to be R
