Frequency offset in OFDM

[ReComm]

Dear Friends,

what the relationship of frequency offset in simple BPSK system and OFDM-BPSK system? (how can i evaluate frequency offset for both system)
are both have the same effect.

if i have BPSK system sensitive to 25Hz for sampling frequency =1MHz , then OFDM with BPSK will have the same value of frequency error or larger or less?

Kindly send a formula to calculate ΔF for BPSK and ofdm.

Thanks

wait your reply,

Hi friends,
simply in OFDM , what is the relationship of BER and Frequency offset?

 

[cokibolong]

frequency offset (FO) occurred by the mismatch between the oscillators in the transmitter and receiver or Doppler frequency and it can cause performance degradation or we can say it can increase BER

Thanks cokibolong ,
I know reasons of Frequency offset , what i need a formula to calculate Frequency offset.
