Fiber transmission of simultaneous optically generated FCC compliant 625 Mbps impulse radio UWB and 80 Mbps 256-QAM IEEE 802.16 WIMAX signals is experimentally demonstrated by using a single directly modulated light source.
We present an all-optical adaptive-antenna radio over fiber transport system that uses proven, commercially-available components to effectively deliver standard-compliant optical signaling to adaptive multiantenna arrays for current and emerging radio technology implementations. The system is based on a directly-modulated reflective semiconductor amplifier (R-SOA) and exploits the interplay between...
In this paper, a technique for demodulation of vector modulated signals like QAM, using photonic techniques is presented. The photonic vector demodulator is capable of converting broadband wireless QAM signals into independent inphase and quadrature optical baseband signals. Experimental demonstration of demodulation of 2.5 Gbit/s QAM modulated 20 GHz carrier is presented. Bit error ratio of the demodulated-I...
