Abstract
With the growth of the Internet, wireless communications also becomes very popular. But the wireless local area network (WLAN) couldn’t achieve the needs of the people. Therefore, Worldwide Interoperability for Microwave Access (WiMAX) striver to spread the wideband wireless networks communication. It is also called wireless metropolitan area network (WMAN) or (WiMAX by Intel). In order to enlarge coverage, IEEE introduces IEEE std. 802.16-2004 as wireless metropolitan area network. In the proposed thesis, it provides one baseband processor. First, building the models of the transmitter, the wireless channel, and the receiver by using SystemC language. This thesis focuses on the proposed receiver that not only overcomes the effects of the wireless channel, but also restores the modulated data. In system simulations, it can prove that the function works correctly. Then, using Verilog language to design and implement the circuit. Finally, verifying the circuit on FPGA. In the architecture of the proposed receiver, it adopts more practical algorithms to build the system. That is that the performances can achieve the basic effect basic on the simplifying algorithms. For the circuit design, it uses MSB of the signals to replace the signal in order to release the complexities of the frame detector and frame synchronization. For frequency synchronization, it adopts the pipeline stages to implement the circuit. This thesis not only builds a whole transceiver conforming to WiMAX, but also designs many simplifying circuit for the proposed system. I hope it is useful for the wireless network.
