Design and Implementation of IEEE 802.16 OFDMA Baseband Transceiver
IEEE 802.16 has been considered as a standard for the next generation wireless communication system. In this thesis, we focus on the design and implementation of a baseband transceiver for a multiple access mode in 802.16, the orthogonal division multiplexing access (OFDMA). The main functions conducted by the transmitter include channel coding/modulation and subcarrier allocation. In the receiver side, an inner and an outer receiver are designed to jointly demodulate the received signal. The inner receiver performs synchronization and channel estimation, while the outer receiver performs equalization, decoding, and subcarrier de-allocation. We consider the downlink scenario and use SCM as our channel mode. A platform with the MATLAB environment is built such that system simulations can be easily conducted. Simulations show that the designed OFDMA receiver can be operated with a mobile speed up to 100Km/hr.
