| The traditional anti-jamming techniques - such as High-speed Frequency Hopping Technology, Spread Spectrum Coding Technology and Time Hopping Technology - are based on the degree of freedom in the frequency domain, or time domain to get the improvement of the anti-jamming performance. The emergence of Multiple-Input Multiple-Output (MIMO) technology, make it become possible to fight against hostile interference with the spatial degree of freedom.This paper proposed a basic technical solution of using MIMO technology to anti-hostile interference. And it is based on the spatial degree of freedom which is generated by the MIMO technology. It avoided the negative impact, which is from the hostile interference, to our communications with the choice of the receiving beams - and this technical program is calld as the interference suppression of multi-beam-choice (IS-MBC). The main works of this paper are as follow:1. This paper briefed the development process and future trend of military communication anti-jamming technology and MIMO technology, proposed the developing trend of anti-jamming technology is multi-domain, and integration. Therefore, it need to extended to the spatial domain from the time domain, and frequency domain.2. This paper proposed the basic theory methods of IS-MBC, and analyzed their theoretical basis and system model. On this basis, it obtained some certain principles and basic rules of devising the spatial anti-jamming program.3. This paper simulated the performance of the IS-MBC-MIMO communication system, obtained its channel capacity in different conditions of hostile interference, and got the visual impression of IS-MBC's performance. Meanwhile, this paper further obtained the performance formula and the reasoning process of it, and verified the correctness of the theoretical findings through the simulation analysis. |
