Abstract :
A simple filter-based orthogonal frequency division multiplexing and frequency division multiple access (OFDM-FDMA) system model which is appropriate for sub-band carrier assignment scheme is proposed. On this basis, a sampling clock offsets estimation and correction method is presented. The method greatly reduced the sampling clock frequency offset estimation difficulties in the uplink situation of multiuser OFDM systems by placing two identical symbols in different location of one OFDM frame. The performance of estimation method is verified by simulation results.
