Preprocessing for PUCCH Decoding

Hi,

I have tried the PUCCH correlation process using BCP COR submodule.

It is written as "To use the BCP, the DSP must undo the rotation before sending the input to the BCP (multiply by (1+j)/sqrt(2))." in the BCP's user guide.

I was confused that I have to rotate the received pilot symbol or received data symbol or both of them.

Regards

Hyekyung.
