Abstract

In this paper, Radio over Fiber (RoF) system of generalized frequency division multiplexing (GFDM) and orthogonal frequency division multiplexing (OFDM) based on geometric shaping (GS) 16QAM is established on MATLAB and Optisystem platform. The transmission signals consist of a GFDM signal and a OFDM signal with bandwidth of 5GHz and 2.5GHz respectively. The frequency interval between the two signals is 10GHz. They were then transmitted onto carriers with a frequency of 60GHz by a quadrature modulator, the central frequencies of the two signals are 60GHz, 70GHz respectively. The transmission distance through single mode fiber (SMF) is 16km. Furthermore, we study the bit error rate performance of the proposed scheme combined with low density parity check (LDPC) codes. In the end of the paper, we analyze the performance of the proposed RoF system and be verified through MATLAB and Optisystem joint simulation that the proposed GFDM scheme with LDPC-GS-16QAM outperforms GFDM scheme with regular 16QAM by at least 15.3dB at bit error rate (BER) of 10-5.
