frequency synchronization of OFDM wireless systems

[rmreddy]

hi all,

it will be of great help if anyone can share their knowledge or material on frequency synchronization of OFDM wireless systems.

i will be in a better position if i can get MATLAB simulation of the same.

OFDM communication standard frames contain preamble which can be used for synchronization. Simply there are tow similar priambles in the frame, calculate phase difference of these preambles and divide by preamble duration

 

[salam2000]

in OFDM use three type preamble
1- short preamble for acqusition.
2- long preamble for fine synch.
3-pilot for tracking
