“…Flaws like multipath propagation and fading are thus more prevalent in both of these standards. The subcarriers of OFDM are selected to be orthogonal to one another throughout the symbol period, preventing inter-carrier interference, and making it a more effective form of multicarrier modulation.The WiMAX physical layer is based on OFDM modulation and is designed for NLOS operation in frequency ranges below 11GHz for licensed bands [2]. In the frequency domain, an OFDM symbol has 256 subcarriers.…”

The IEEE 802.16 WiMAX standard for BWA (Broadband Wireless Access) was designed to offer end users high transmission data rates across wider regions.Wireless communication requires MIMO systems because they enable data to be sent and received through multiple antennas. This study examines how the MIMO-WiMAX physical layer performs while using different modulation techniques and channel coding approaches the BER performance of WiMAX systems, the Alamouti Space Time Block Code method for MIMO is being investigated.

WiMAX is intended for fourth generation wireless mobile communications where a group of users are provided with a connection and a fixed length queue. In present literature traffic of such network is analyzed based on the generator matrix of the Markov Arrival Process (MAP). In this paper a simple analytical technique of the two dimensional Markov chain is used to obtain the trajectory of the congestion of the network as a function of a traffic parameter. Finally, a two state phase dependent arrival process is considered to evaluate probability states. The entire analysis is kept independent of modulation and coding schemes.
