Carrier Frequency Offset (CFO) synchronization is a crucial issue in the implementation of Orthogonal Frequency Division Multiplexing (OFDM) systems. Since current technology tends to implement different standards in the same wireless device, a common frequency synchronization structure is desirable. Knowledge of the physical frame and performance and cost system requirements are needed to choose the most suitable scheme. This paper analyzes the performance and FPGA resource requirements of several Data-Aided (DA) and Decision-Directed (DD) schemes for four wireless standards: 802.11n, 802.16d, LTE, and DVB-T/H.
