Area and power efficient design of coarse time synchronizer and frequency offset estimator for fixed WiMAX systems

Targeting fixed WiMAX systems, this paper presents a new architecture for coarse time synchronization and carrier frequency offset (CFO) estimation. The proposed architecture is based on a two-step approach where the data-paths are decoupled to individually optimize performance and area. Implemented with 0.13 mum CMOS technology, the results show that the proposed architecture has advantages of less silicon area and power consumption as well as better performance compared to the previous joint approach.
