Abstract
An adaptive algorithm for a single sinusoid detection using IIR bandpass filier with parallel block structure has been proposed by Nishimura et al. However, the algorithm has three problems: First, it has several input frequencies being impossible to converge. Secondly, the convergence rate can not be higher than that of the scalar structure. Finally, it has a large amount of computation. In this paper, a new algorithm is proposed to solve these problems. In addition, a new structure is proposed to reduce the amount of computation, in which the adaptive control signal generator is realized by the parallel block structure. Simulation results are given to illustrate the performance of the proposed algorithm.
