Changing fir filter coefficients at samples rate

Baccouche__Bessem

Hi,

I'm using a  sparse complex filter for communication channel Simulation. So I have to Change the filter coefficients (so only the values not the positions) at sample rate. So for each filter execution I have to call init function. 

It turns out that if I Change the coefficients (using init function) for each sample the calculation is  ca. 100X slower than changing the coefficients for each 500 samples.

Is there a way to reduce the computaional Costs of changing the coefficients?

thank you.

I am afraid we couldn't help much with the pipeline you describe - this is "by design" behavior.
