LMS FILTER USING STM32F4

Question asked by mohit rai on Sep 23, 2017

Hello,

 

I am using stm32f4 discovery. I want to use LMS filter for my application, but when I have initialized my filter coefficient by 1 or 0 and 0.5  its filter coefficient is not updating.

step size is 0.01. and filter output is also constant. error output is changing.

what can be the cause of this problem?
