Dear Guys I am Ganesh, and i would like to ask you'll a question on erle. I calculate ERLE as described below: Pd=filter(1,[1, -0.98],d.^2); Pe=filter(1,[1, -0.98],e.^2); erle=10*log10(Pd/Pe) I am trying to calculate erle in Matlab, but by usin

Dear Friends Just to ask you'll on what is the difference between ERL and ERLE ? I have done plot's where the range of the ERLE is always in the positive, but then, some other researches do not have ERLE, but they have ERL, and their plot is in the negative regio

Hi,all I have implement an AEC algorithm (Frequency Domain NLMS) on DSP (TI c5509), but when I test it in real room the ERLE is 16dB(with white noise), will test by compositive speech source with line_in the ERLE is 25dB. But, I always see that some AEC product's ERLE can get 25dB-30dB, So I want to konw the method they test. 1,what's the test source. white noise or speech signal? ...
