Feedforward Active Noise Control System with FxLMS (Jun, 2017)

adaptive-algorithm-for-noise-cancellation

The design is proposed to get a signal with reduced noise at low frequency. The parameters used here are to simplify the computation and enhance the filtering capability using feed forward Adaptive filter. The filter follows causality so as to control maximum noise reduction and attenuation bandwidth. Systematic analysis is computed to predict noise performance. This methodology uses two 24 tap filter, an FIR filter, and white noise to produce efficient output. Desirable length of the filter is chosen to reduce Hardware complexity. Filter follow a sequential structure to save resources and clock cycles. Two adaptive filters are cascaded to maintain causality. An FxLMS algorithm is proposed in which filter coefficients vary as they update weight functions to the signal to make the system stable.

spectrum

Spectrum analyzer system using a 512-point FFT, in a Cyclone IV FPGA. Reads i2s audio from the codec and then does all FFT/VGA functions. Nios just reads the FFT result and draws the display bars. VGA frame buffer on-chip. VGA signals generated on-chip. See the included video files to watch it in action.
