I need to implement non-linear adaptive filter in MATLAB. We have
dsp.BlockLMSFilter
dsp.LMSFilter
dsp.RLSFilter
dsp.AffineProjectionFilter
dsp.AdaptiveLatticeFilter
dsp.FastTransversalFilter
dsp.FilteredXLMSFilter
dsp.FrequencyDomainAdaptiveFilter
The above all are all linear adaptive filter. But i want to implement non-linear adaptive filter. Could anyone let me know how to do so? Is there any existing toolbox available in MATLAB or should we write our own? Or in the above mentioned is anything a non-linear adaptive filter??

Hi @Monica,
MATLAB doesn't provide a built-in non-linear adaptive filter in DSP System Toolbox. But you can:
  • Code Volterra LMS/RLS — extend the input vector to include non-linear terms
  • Code Kernel LMS/RLS — using kernel trick (e.g. Gaussian kernel)
For more details, look into following MATLAB File Exchange:
