You need to compute something like a/b. Re-write as a*c where c = 1/
b.
You can use a lookup table to map from b to c. This works really well
for fixed-point processors.

Hi,
I am implementing an equalization algorithm for OFDM system. For this,
after calculating the channel taps, we need to divide the complex
sub-carrier symbols with complex tap values. I was wondering this division
takes too many cycles for the DSP implementations. So is there any way of
doing equalization in a better way or we have to live with this expensive
division operation.
