FPGA Implementation of Carrier Frequency Offset Estimation in B3G MIMO OFDM System
Frequency offset estimation algorithms based on time domain training sequence in MIMO-OFDM system were demonstrated. With a view to hardware implementation of frequency offset estimation algorithms in MIMO-OFDM system, the complexity of the algorithm implementation was analyzed. In order to make the frequency offset estimation algorithm m MIMO-OFDM system less complicated during FPGA implementation, a simplified implementation scheme was brought forth, and statistics on resource occupation of such a scheme in VirtexⅡ-Pro series FPGA of Xilinx Company was given, while the scheme was verified on B3G TDD system hardware platform. Study shows the simplified implementation scheme is applicable in hardware implementation of B3G MIMO-OFDM system frequency offset estimation algorithm.
