mu = 0.05; % Set the step size for algorithm updating. With the required input arguments for dsp.LMSFilter prepared, construct the LMS filter object, run the adaptation, and view the results. Get lms = dsp.LMSFilter(12,'Method','Sign-Data LMS',... 'StepSize',mu,'InitialConditions'...
Create a dsp.LMSFilter object to represent an adaptive filter that uses the LMS adaptive algorithm. Set the length of the adaptive filter to 13 taps and the step size to 0.8. Get mu = 0.8; lms = dsp.LMSFilter(13,'StepSize',mu) lms = dsp.LMSFilter with properties: Method: 'LMS'...
The block diagram of the design of the pauseable nonlinear adaptive backscatter filter is presented in Fig. 9. The filter’s final output is the SAF-LMS algorithm’s output before the target echo peak arrives. The filtering algorithm suspends after the arrival of the target echo peak, and th...
Filtered reference and filtered error algorithms are also derived for multiple-input multiple-output (MIMO) linear systems, although the filtered reference algorithm is found not to have a simple block diagram interpretation. In the MIMO case, the filtered error form of the algorithm can have ...
