Hi myeongsuk,
Implementing Active Noise Control (ANC) for a mobile phone's location using Simulink involves several key steps and considerations:
- Ensure the microphone's sampling rate and quality are adequate, and be aware of potential latency issues.
- Design and simulate an ANC system in Simulink, starting with simulations using recorded audio samples from the phone.
- Investigate methods for streaming live audio from the phone's microphone to Simulink, possibly using MATLAB Mobile™ or a custom app.
- Use adaptive filtering techniques for the ANC algorithm and estimate the secondary path specific to the phone's audio output path.
- Initially test the system in a controlled environment, then move to real-world scenarios to evaluate effectiveness and optimize.
- Consider integrating the ANC system within a mobile app or the phone's firmware, keeping in mind battery usage and normal operation.
Mobile platforms may introduce limitations such as real-time processing capabilities and latency. Additional development tools and languages may be required for app creation. This project is complex due to integration and real-time processing challenges, and it's advisable to start with a proof of concept focusing on real-time audio capture and processing.
