Hi Everybody
Im new here und i have a question from my Bachelorthesis
In a Matlab system ,I have the estimated transfer function from the channel,
simply ch_est (in frequency domain), and that is a 64x1 Matrix
You can say that the channel is a FIR Filter with finite impulse response.
I have heard that, the inversion of a FIR Filter is always a IIR Filter, with
infinite impulse response
I have used the simplest method, expres 1./ch_est and then taking back in the
time domain, but the impulse response from my inverse Filter is finite, also a
FIR filter
How can i get a IIR Filter, when i inverse the FIR Filter ?
Many thanks
