Abstract
In this Thesis, we propose a baseband physical layer transceiver architecture according to the 802.16-2004 OFDM specifications. The baseband channel model is defined according to the SUI channel model, with Additive White Gaussian Noise (AWGN), carrier frequency offset, and sampling clock offset. To recover the data, suitable algorithms are used to detect the symbol boundary, to estimate and compensate carrier frequency offset and sampling clock offset, to interpolate, and to perform the frequency-domain equalization in the receiver. Moreover, the TMS320C6416 DSP of Texas Instruments (TI) is used in software implementation. By a sequence of code development flow, the operation cycles are reduced and the inner receiver is able to meet the real time requirement.
