- Abstract
For the shortcoming that the satellite navigation receiver is easy to be interfered, a joint space-time method is researched and an improved complex Hermitian positive definite matrix inversion method is proposed based on matrix inversion part. First, the joint space-time method is presented. Second, according to the analysis of the traditional Hermitian positive definite matrix inversion method, an improved method is proposed, and the detailed process is given. Finally, the computations of addition, multiplication, division are compared based on Digital Signal Processing (DSP) hardware platform. Simulation results show that the computation of the improved method is significantly reduced. The improved method is simple, reliable, and easy to implement and can be applied in engineering applications where real-time requirement is strict.
