- 초록
- In this paper, we present the simulation results of FFO(fractional frequency offset) influences on PLC preamble correlation based PLC synchronization in DOCSIS 3.1 Downstream. FFO makes inter-carrier interferences and breaks orthogonality in OFDM based transmission system. It degrades the performance of OFDM by reducing SNR(signal to noise ratio). The performance of PLC synchronization is influenced by the reduced SNR caused by FFO. We analyzed the influences of FFO on PLC synchronization by applying various FFO values. We showed the PLC synchronization performances to various FFO values and discussed the results considering requirements of FFO compensation performance in OFDM signal reception.
