碩士 === 國立清華大學 === 電機工程學系 === 98 === In recent years, technology of communication devices is developed rapidly due to the growing demand for transmission system. In order to provide large bandwidth for high quality services, realizing a transceiver for optical OFDM system becomes very important. In this thesis, we propose a design of the baseband receiver with a set of 16-way parallel processing for the optical OFDM system. The baseband receiver contains the frame detection, CFO estimation and compensation, channel estimation, and equalization. We complete the hardware design of the system and show the simulation results under the optical channel. Besides, this thesis proposes a fast Fourier transform(FFT) with high parallelism based on pipeline architecture and integrate it in optical OFDM system to reach the high-throughput goal. Finally, the FFT processor is designed and implemented as a single chip using 90nm UMC CMOS technology and Faraday cell library. The chip with a set of 16-way parallel processing can achieve the throughput up to 2.67GS/s.
