Abstract According to control the implementation of communication systems with respect toIEEE standard committee and need to improve wireless communications in our country the study of fixed wireless communications standards seems to be necessary In this thesiswe study IEEE 802 16 and in detail we study the OFDM Physical Layer of IEEE802 16 2004 The receiver and transmitter model is simulated in MATLAB and is readyfor implement In this model all blocks contain the scrambler FEC adaptive modulation and IFFT issimulated based on the standard document published in 2004 Besides the transmitter main block of receiver containing the inverse line and equalizer for compensation of themultipath channels is simulated The synchronization specialize in symbol timing synchronization in this standard isanother subjects of this thesis Talk about all kinds of synchronization and their erroreffects on data detection study about purposed methods like ML estimation orcomputation of correlation function and cross correlation function for symbol timingsynchronization and purposes a new method with less computation and more accuracy areinserted in this report
