Abstract

In this paper, the CORDIC-based OFDM baseband receiver is proposed to fulfill the joint carrier synchronization and channel equalization algorithm. The versatile arithmetics of CORDIC are employed to realize various baseband operations, including “gain compensation”, “phase compensation”, “initial gain and phase estimation”, and “derotator”. The CORDICs are configured to perform these computations by setting a few simple parameters at different time-slot. The FPGA prototyping of CORDIC-based OFDM baseband receiver is presented to on-line demonstrate the constellation diagram and off-line measure the symbol error rate (SER). In addition, the maximum uncoded data rate of FPGA prototyping is 72 Mbps for 64-QAM modulation.
