Improvement of Compressive-sensing Based Sound Source Localization by Using Homotopy Method
김용현 · 이정훈
Yong-Hyun Kim and Jeung-Hoon Lee
The iterative hard thresholding (IHT) algorithm is a popular approach for solving compressive-sensing based sound source localization. However, IHT has major drawbacks, such as excessive iterations, or failure to converge if the algorithm step size is inappropriate. In this study...
