Abstract

In this paper we propose novel modulation technique based of quaternion signals aimed at incrising the capacity of Radio-over-fiber (RoF) systems based on OFDM technology. The application of hypercomplex quaternion signals processing has already demonstrated many advantages over the conventional analytical signals. The mathematical and simulation models of the quaternion QPSK modulator and demodulator are presented. Next, the improved scheme for OFDM RoF system is provided taking into account the quaternion signal processing. Simulation and evaluation of the proposed models were carried out by transmitting the QQPSK signal over the RoF system with AWGN wireless channel. The obtained BER vs SNR results for proposed modulation technique were compared to conventional QPSK providing double channel capacity with a little degradation of the noise immunity for QQPSK technique.
