Summary: | 碩士 === 國立交通大學 === 電機學院碩士在職專班電信組 === 94 === IEEE 802.16 is a standard system specified by IEEE (Institute of Electrical and Electronics Engineers) for next generation broadband wireless access. A digital receiver is designed in this thesis for the IEEE 802.16-2004 OFDMA PUSC (Partial Usage of Subchannels) downlink system. The receiver’s functionalities include detection of downlink preamble energy, detection of guard interval length, carrier frequency offset estimation, detection of downlink preamble boundary, detection of downlink preamble PN (Pseudo Noise) code, and channel estimation. Simulation results show that the design is away from the ideal one only within 2-dB.
