Abstract
In this thesis, we propose a subscriber station (SS) physical layer (PHY) transceiver architecture for IEEE 802.16a OFDM mode. Algorithms for symbol boundary detection, carrier frequency offset (CFO), timing offset (TO) detection and compensation, guard interval detection, and frequency-domain equalization (FEQ) as well as channel interpolation and channel gain update are embedded in this receiver. Since IEEE 802.16a standard contains various mandatory requirements, such as transmission type, transmission bandwidth, carrier frequency band, data throughput, etc., the main consideration of the proposed architecture is then flexibility and robustness to conform to various kinds of channel combinations. Simulations are made under various baseband equivalent channel models, and the simulation results show that the proposed architecture can fulfill the bit-error-rate (BER) requirements of the standard.
Simulation programs are developed with cycle-based style so that the latency and complexity of the hardware could be evaluated during the procedure of architecture design, and can thus fasten the IC design procedure in the future.
