FFTC Guard removal for LTE 10MHz

Hi All,

 Is it possible to configure FFTC hardware to remove guard carriers in LTE and to get only the 600 useful data subcarriers ?

 Thanks in advance.

Regards,

    Hi Sandeep,

    Yes, it's possible to configure FFTC to remove guard bands and get the useful data subcarriers. You have to essentially setup 3 different FFTC RX FDQ. One for the left guard band, one for the useful carriers, and one for the right guard band for each packet.

    You can check more details of this implementation in section 6.4 of the AIF2<->FFTC App Note below:
