Multi-channel optimal adaptive filtering for time-delay measurement systems
Chunyan Han, Yuan Lin, Jun Fang Wei · 2017
This paper is concerned with the multi-channel optimal adaptive filtering issues for time-delay measurements systems with unknown noise statistics. Firstly, the multi-channel time-delay system is reconstructed as an equivalent delay-free one by means of the measurement reorganization technique. Based on the altered system model, two adaptive filtering algorithms are developed by applying the projection theorem and two different noise estimation methods. Finally, an example is presented to illustrate the efficiency of proposed estimators.
