Adaptive line enhancemment application - function [ALEstruct]=ale(f,fs,munoise,sigmanise,mulms,ncoef,dur) function [ALEstruct]=ale(f,fs,munoise,sigmanise,mulms,ncoef,dur)function to perform adaptive line enhancement using LMS algorithm and an adaptive FIR filterALE concept enhances a single tone signal (frequency f) affected by white noise (mu,sigma)REQUIRES FILTER DESIGN TOOLBOX, SIGNAL PROCESSING TOOLBOX INPUTSf: frequency of sinusoidfs: sampling signal of sinusoid (At least 2f)munoise, sigma: mean and variance of white noisemulms, value of the step parameter in the LMS algorithmncoef: number of coefficients of the FIR filterdur: simulation time in number of signal periodsOUTPUTSALEstruct: a structure with fields.weights: the filter's weights after finishing iterations.error : evolution of error signal during simulation.output: output of the filter.signal: a copy of the input signal.desired: a copy of the desired signal in the LMS adaptive scheme. Note: e(n)=output(n)-d(n).mse .mmselms .emselms .meanwlms .pmselms: results of predicted and simulated filter behavior in terms of MSE, minimum MSE, excessMSE, coefficient vector means and predicted learning curve (pmselms).
