Hi all I am doing an implementation of Filtered X-LMS for active noise cancellation in lab set up. I do not have a directional speakers and high efficient mic. I have simple speakers and a jack mic. Will I be able to carry out the experiment efficiently (with 10dB noise reduction)in matlab simulink? I have modelled the problem in Simulink and connected the speakers and mics. I also tried out secondary path estimation. But by using the acoustic signal captured by the mic for processing, the LMS filter doesnot converge. Should I do any additional processing such that mic capture an accurate acoustic output so that LMS works fine for secondary path identification.
