Re: what is Preamble?

what i know about Preamble
it is a technique to make synchronous between Tx & Rx
it sends a certain byte to make order to Rx to begin to rreceive and process data
for example on data network; computer send this byte '10101011'
so receiving computer when receive 0101... it make attention to be ready
until it receives ' 11' then it begins to process the next bytes

The following paper gives answer to all your questions regarding Preambles in 802.16 :

"Design and Simulation of a baseband transceiver for IEEE 802.16a OFDM-MODE subscriber stations", Yang, Lei, Chiueh, The 2004 IEEE Asia-Pacific Conference on Circuits and Systems, Dec 6-9,2004
