Active Noise Control (ANC) Primarily Based on LMS Algorithm with Wavelet Transform Enhancement
Active Noise Control (ANC) predominantly utilizes the LMS algorithm; however, its effectiveness diminishes when processing broadband noise signals under low signal-to-noise ratio conditions. The primary factor affecting control performance is the autocorrelation distribution of input signals. Wavelet transform effectively eliminates signal autocorrelation, making its integration into ANC systems a viable solution for these challenges. Implementations typically involve modifying the standard LMS structure by incorporating wavelet decomposition for preprocessing input signals before adaptive filtering.
