OFDM Tutorial Series: Carrier Frequency Offset (CFO) Estimation Correction

[@sdrnovice2000]

This is so valuable! Thank you. I was doing some frequency offsets of IFFT length 3072 OFDM literally today and noticed an exponential decay instead of a frequency and phase shift. Had forgotten the “j” in the exponent. Most of your slides here mis this as well. We’ll be fine though

Hi 1- @7:36 how can the AGC come after the ADC blk ? isn't supposed to be before ? 2-@9:49 top of slide it is mentioned transmitted samples after DFT of carriers , do we take the DFT of the subcarriers to get signal in time domain ? 3-@9:49 if the phase offset is function of time then why at sample n in time you did not account for the phase shift due to the time spent in the guard period Ng ? you are only accounting for phase offset due to signal starting from sample 0 to sample n

Note the dotted line back to the RF Front End. So if saturation we peal off gain.

@@silicondspcorporation7864 your ans is not in the same format as my questions they are not numbered nor they are time lined i do not know what are you talking about

can you share this presentation ?? a link in description may be...?
