基于迭代优化算法的MVDR空间谱估计的So C实现
SoC implementation of MVDR spatial spectrum estimation based on iterative optimization algorithm
摘要
Abstract
Aiming at the large amount of calculation and time-consuming in matrix inversion of MVDR algorithm,a coordi-nate descent method based on iterative optimization is proposed.The matrix inversion is converted into optimum solution of a linear equation.Meanwhile,SoC design based on FPGA is adopted,the spectrum peaks are searched in the processor and the iterative optimization algorithm is implemented on the dedicated hardware for accelerating matrix inversion.The simula-tion result shows that the error between the calculated result and the actual result is very small.The hardware test shows that the SoC design can effectively search the peaks of the spectrum.关键词
