Hello, I am trying to compute a solution using the least- square- error principle to an overdetermined system of equations. The equation is as below: Error = summation (y[n] ? summation (ai x[n-i] ) )... in 'ai' term `i' is subscript where `n'

Hi, I am designing an obstacle detection system using SONAR. I am using a 50Khz signal for transmiting. The application needs to determine the exact frequency of the echo received from the obstacles. The expected range of the echo signals is 45 - 55 Khz and I need an accuracy

Dear All, I am currently simulating the performances of LMS and RLS adaptive filters. Specifically, I am looking at their robustness. Theoretically, in H-infinite sense, LMS is a robust filter whereas RLS is not. Through my simulation, I would like to show or prove this theory

hi! i am trying to use LEC provided by Texas instruments packaged as an example in development kit for XDAIS complaint algorithms on C6711. but this algorithm appears to be not working properly. it damps the echo part just a little bit. has anyone used it.. can i

Can someone tell me what the difference is between a Line Echo Canceller and a Network Echo Canceller? To me, it seems that the only difference is the echo path delay. Or say, they are just different echo paths. If that's right, then a echo canceller with, say, 128ms delay sho
