Title :
Adaptive Marple spectrum estimation
Abstract :
A fast sequential Marple algorithm that can be applied to adaptive control and interference suppression with computational complexity being 25M+37 MADPR (multiplications and divisions per recursion) as contrasted with nM+9M2+2n+25M-3 of the batch Marple algorithm is developed by using the spectral structure of the coefficient matrix of the normal equation. Computer simulation results are included to show the correctness and effectiveness of the algorithm.
