Paper Abstract

The demand for high speed in wireless communication is a big concern since the number of connections is increasing. The employment of higher carrier is strongly recommended and millimeter wave (mm-wave) frequency are necessary in the future. In this paper, we propose the generation and the transmission of multiband signal for millimeter-wave Radio over Fiber (RoF) system using the full spectrum of 200 -300GHz for downlink transmission of 10 Gb/s On off Keying (OOK) and 40 Gb/s Differential Quadrature Phase Shift Keying (DQPSK). An optimized Optical Flat Comb Source (OFCS) based on dual-arm Mach-Zehnder Modulator (MZM) is employed in order to generate 5 carriers with 25 GHz spacing and centered around 250 GHz. For 10 Gb/s OOK and 40 Gb/s DQPSK, the system performances are evaluated by measuring the Bit Error Rate (BER). In addition, we have studied the Error Vector Magnitude (EVM) for 40 Gb/s DQSK system.The obtained results have been done for single and multiband channels. At first, we have explored the effect of the optical fiber in the performance of our system. The optical fiber is inserted after each modulatorand after the local oscillator (LO) for path compensation.The optical delay line has an important role in reducing interference between channels. Furthermore, we discuss the performance of the system in back to back transmission in different cases such as without wireless link and with wireless link. Finally, we have studied the wireless link distances for acceptable BER below Forward Error Correction (FEC) limit BER 3.8x10-3 and EVM for each modulation format. The transmission link length is about 2 m. The generated signal is used for short range indoor wireless systems.
