Fast implementation of LCMV anti-jamming algorithm for GPS navigation

摘要

LCMV algorithm is a common-used anti-jamming method for GPS navigation. It requires the complex computation of matrix inversion. In this paper, an improved method for complex matrix inversion based on Gaussian elimination is given. The combination of C and assembly language program design process of improved algorithm based on Digital Signal Processor hardware platform is developed. Experimental results show that the time consumption of improved complex matrix inversion method based on Gaussian elimination is the least, compared to the method of the original complex inversion based on Gaussian elimination and the method of the traditional direct matrix inversion.
