Abstract :
A 2 × 2 MIMO RoF system with 64 QAM DSB Single Carrier modulation at 60 GHz is demonstrated in this paper. 60-GHz technology is one of the best solution for multi Gb/s wireless applications because of the large 7 GHz spectrum. 64 QAM modulation system is employed and transmitted over 25 km and received with data rate upto 40Gb/s. Optical coupler is used to implement the 2×2 MIMO system. Eye diagrams and constellations are used to evaluate the efficiency of the system. Bit error rate(BER) and Signal to noise ratio(SNR) are also used for performance analysis of the system.
