MATLAB: LMS filter export

dspfilteringlms

Hello, Is it possible to export the h[n] of an LMS filter created based on two training signals using the following commands:

hlms2=dsp.LMSFilter('StepSize', 0.0001, 'Length' , 600)
[output,err]=step(hlms2,x_echo_trainset_orig,new)

in order to use it with another signal as echo remover?

Best Answer

The step method returns the filter coefficients as an optional output argument:

   [output,err,coeffs] = step(hlms2,x_echo_trainset_orig,new);

HTH.

MATLAB: How to filter multichannel data for Adaptive Filters in MATLAB 7.5 (R2007b)

The FILTER function in the Filter Design Toolbox does not support multichannel data for Adaptive Filters. It is supported only for Fixed-Point Filter and Multirate Filter Syntaxes.

A workaround for this would be to loop through each channel to process the data.

MATLAB: How to properly use the Cascaded integrator-comb (CIC) filter in the cascade filter structure to filter a signal in Filter Design Toolbox 3.0 (R14)

Currently, the CIC filters only work with the built-in signed integer data types such as INT8, INT16, and INT32.

The CIC filter must come first in the cascade. The following code shows how the code should be written:

L = 7;     % variable interpolation factor
N = 4;     % number of stages
hcic = mfilt.cicinterp(L,1,N);
dcGain = L*gain(hcic);
hscalar = dfilt.scalar(1/dcGain);
hscalar.Arithmetic = 'fixed';
Hcas = cascade(hcic,hscalar); % Note that the CIC comes first
x = randn(1,64);
y = filter(Hcas,int16(x));

Please note that the CIC filter (hcic) must come first in the cascade. The reason is that output of the CIC filter is an INT16 in this case and the hscalar filter can interpret that data type. In Filter Design Toolbox 3.0 (R14) the CIC filters do not work with the output that is an embedded.fi object. In this example, the output of the hscalar filter is an embedded.fi object.
