摘要:
为了对抗军用通信中各种人为干扰,提出了具有空时频联合分集效果的空时慢跳频-多输入多输出(STFH-MIMO)通信抗干扰系统,该系统采用了STFH编码算法和正交相干滤波(OCF)译码算法,在保证MIMO通信高速大容量传输的同时亦提升其抗干扰性能。通过建立该系统软件平台,仿真验证系统对宽带干扰、部分频带干扰以及跟踪干扰的抗干扰性能,仿真结果证明该系统具有良好的抗干扰效果,获得跳频增益约10 dB,分集复用增益约18 dB,抗干扰性能得到明显提升。
Abstract:
In order to combat various human interference in military communications, this paper proposes the space-time slow frequency-hopping multiple input multiple output (STFH-MIMO) communication system with the effect of space-time-frequency joint diversity. The system uses a STFH code algorithm and orthogonal coherent filtering (OCF) decoding algorithm, which can ensure high speed and large capacity transmission in MIMO communication, and at the same time, enhances its anti-jamming ability. Through establishing this system software platform, the simulation verifies that the system has good anti-interference effect to resist broadband interference, partial band interference and tracking interference. The system gets the 10 dB gain from frequency hopping and 18 dB gain from diversity multiplexing, and anti-interference effect is improved obviously.
