Abstract :
This paper presents a study of generalized chirp-like (GCL) sequence for frequency synchronization in IEEE 802.16- 2004 standard application. GCL sequence, a special class of polyphase sequence that it is, has a lower PAPR preamble for synchronization in OEDM system than PN sequence based preamble. The method of synchronization is based on Schmidl and Cox. The result shows that, GCL sequence based method also has a better estimation result of integer frequency offset than PN sequence due to its good cross-correlation property.
