Hi
How to design correlator (for example used in preamble detection) in hardware (vhdl/verilog)?
it involves finding sq. and sq. root etc..

Thanks

I think u are not asking about total correlation block.
If u want only magnitude block calculation as u said "sqr and sqrt" ,u can use approximation circuit
for ur magnitude block to reduce area.
