Design and simulation of a baseband transceiver for IEEE 802.16a OFDM-mode subscriber stations

Abstract

In this paper, we propose a subscriber station (SS) physical layer (PHY) inner transceiver architecture for IEEE 802.16a OFDM mode. Algorithms for symbol boundary detection, carrier frequency offset (CFO), timing offset (TO) and frequency-domain equalization (FEQ) as well as channel interpolation are embedded in this receiver. Simulation results show that the proposed architecture can fulfill the bit-error-rate (BER) requirements under most situations.
