Summary :

In this letter, a compact CORDIC algorithm is proposed to efficiently implement a synchronization block for carrier frequency offset (CFO) in OFDM modems. The compact CORDIC algorithm allows us to combine a CFO estimation block and a CFO compensation block into a single CFO synchronization block. It is shown by FPGA implementation results that the compact CORDIC algorithm can achieve a significant reduction in hardware complexity and latency for implementing the synchronization block in OFDM modems.
