How to introduce Doppler Shift on OFDM systems?

Hello, I am looking for a MATLAB code for ofdm that introduces doppler effect due to relative motion of Tx/Rx. Thanks in advance

Effect of sampling frequency change in OFDM

hi , frequency offsets are due to channel delay spread (coz of channel impairments ) and doppler spread ( movin vehicles) suppose ur upconvertin RF frquency is @ 2 Ghz and IF :100 MHZ , ur transmitting frequency will be 2100 MHZ so if ur channel delay spread is say 10 HZ ur recieved signal at RX will be 2100. 000 010 hz , ur receiver d

testing ofdm system for varying dopler frequency

doppler has a devastating effect on ofdm signal due to ICI and loss of synchronizarion ,unless adequate compenasation techniques are applied
