Abstract
An implementation of orthogonal frequency division multiplexing (OFDM) multimode fiber communication system test bed developed in simulink is proposed in this paper. The system design and implementation is discussed. Based on the simulation system, the effect of different fiber lengths, various numbers of the OFDM subcarriers and transmission data rates on this system has been considered. The simulation results show that with the increase of fiber lengths, the systems bit error rate (BER) increase as follow. In addition, even though using a large number of subcarriers can reduce the amplitude variation cause by the magnitude response of the multimode fiber since the bit rate per subcarrier signal is small, the BER from the system with large number of subcarriers is not always better than the BER from the system with small number of subcarriers. The simulation system test bed is useful to make the following studies more convenient, and also is helpful to establish a practical system.
