Performance analysis of 802.61a

With the ever increasing popularity of wireless internet, its scale is broadening. While the IEEE 802.15 standard provides the parameters necessary for a wireless personal area network (WPAN), the IEEE 802.16a standard provides broadband wireless access (BWA), or a wireless metropolitan area network (WMAN). Popularly referred to as Wi Max, the standard uses cellular topography with a base station and subscriber station and cuts down on infrastructure and thus can be used in most environments. The 802.16a standard can take advantage of the popular OFDM modulation technique. This thesis takes a developed synchronization algorithm and tests its performance on 802.16a. In addition, it tests the standard's performance in different types of channel. Various techniques are evaluated including interleaving and antenna diversity. The 802.16a standard employs a form of transmit diversity called Space Time Coding. The transmit diversity is compared with Maximal Ratio Combining receiver diversity. The evaluation was done in simulation developed in Matlab; the simulations show drastic improvement when using the aforementioned techniques, particularly diversity.
