Özet
In this work, after some of the commonly used symbol timing synchronization algorithms used in orthogonal frequency division multiplexing systems are examined, a two-step (coarse and fine) symbol time offset (STO) correction algorithm based on Schmidl & Cox [1] approach is investigated in Simulink model. Subsequently, relying on this Simulink model, the STO algorithm is implemented on ZYNQ ZC706 XC7Z045 FPGA working fully parallel at a clock rate of 200 MHz. The implementation results are compared with the other related studies in the literature.
