Short summary
Carrier synchronization is a crucial part of any wireless receiver, which is required due to frequency and phase offset. In this work, we compare interpolation techniques with different FFT-based carrier synchronization methods. Applied to reference burst types specified in the DVB-RCS2 standard, trade-offs between communication performance and hardware implementation efficiency are shown. Furthermore, we present and analyze a flexible IP core implemented on FPGA.
