空时联合抗干扰降维处理的设计与实现

Design and Implementation of Space-Time Joint Anti-Interference and Dimensionality Reduction

摘要: 针对星地测控链路采用的空时联合抗干扰方法中计算量大、系统复杂、难以适应复杂电磁环境干扰抑制等特点，提出了简单迭代法与高斯–赛德尔迭代法组合方法。采取降维处理，将空时数据处理的维数分成若干段，段内采用简单迭代法，段外则采用高斯–赛德尔迭代法，以增强算法的收敛性和并行性。通过仿真，验证了这种组合方法的可行性。

Abstract: Aiming at the characteristics of the space-time joint anti-jamming method adopted by the satellite-to-ground measurement and control link, such as the large amount of calculation, the complexity of the system, and the difficulty of adapting to the interference suppression of the complex electromagnetic environment, a combination method of simple iteration method and Gauss-Seidel iteration method is proposed. Dimension processing, dividing the dimension of space-time data processing into several segments, using simple iterative method inside the segment, and Gauss-Seidel iterative method outside the segment to enhance the convergence and parallelism of the algorithm. Through simulation, the feasibility of this combined method is verified.
