Abstract
Wireless communications is a rapidly growing industry nowadays. As the requirement of transmission rate and quality is higher and higher, more related researches are developed. The technique of OFDM is proposed with some benefits. The higher spectral efficiency provides higher transmission rate. Besides, OFDM can reduce the distortion due to multi-path fading to improve the transmission quality. These advantages make OFDM to be a suitable technique for typical metropolis environment. In several communication standards, WiMAX provides the higher data rate, the farther transmission distance, and the better communication quality. In this thesis, we implement a uplink WiMAX transceiver on a development board with FPGA and PPC based on the IEEE 802.16-2004 WirelessMAN-OFDM standard which is used for fixed transmission applications. The physical layer architecture is accomplished on the FPGA. On the other hand, the basic MAC is achieved with the PPC to provide the communication interface between PC and FPGA. This system can be verified by the close loop testing, that is, transmit analog signal generated by subscriber station transmitter to the base station receiver on the same board. Then we can send the transmission data from PC to this system, and get the decoded result back. The contribution of this thesis can be summarized as follows. We implemented the uplink WiMAX system on the development board with FPGA and PPC. Users can control and verify this system from PC conveniently. Besides, the modularly designed structure makes users do any modifications easily. This provides an integrated hardware platform for the further researchers.
