BER AND GAIN ANALYSIS OF IEEE 802.16 STANDARD FOR BROADBAND WIRELESS ACCESS (BWA) IN 32-QAM MODULATION TECHNIQUE IN 4X4, 5X5 AND 6X6 ANTENNA DIVERSITY

WiMAX (Worldwide Interoperability for Microwave Access) physical layer is basic of 3G and 4G wireless communication Technology. This technique gives rise to the advanced technique. So in this thesis we are going to estimate the BER and SNR analysis of Wi-MAX Physical layer in symmetrical antenna diversity like n transmit antennas and n receive antenna in 32-QAM modulation technique. For this first we made the MCCDMA system that is basically a multicarrier system for high speed data rate transmission. And finally we merge this system to MIMO diversity for multiple transmit and multiple receive antennas to enhance the capacity of system. So result shows that if we increase the antenna diversity we get lower BER at and higher SNR that leads to enhance the system capability. In this thesis for MIMO implementation ZF equalization technique is used for transmitting for multiple transmit antennas and OSTBC code is used to determining the signals without knowing the channel state information at the receiver end
