Digital Signal Processor System for Active Noise Control with Improved Secondary Path Estimation

摘要

The paper presents a DSP system for active noise control. The secondary path modeling is improved using insertion df additive noise. The system works in real time (with a DSP microcomputer such as ADSP21060 -Analog Devices). The paper is organized as follows: section Ⅰ represents a introduction in noise control system, section Ⅱ presents the approach for modeling the secondary path that improves the system performance, section Ⅲillustrated the implementation and the main results and section Ⅳ presents the conclusions.
