Abstract

A frequency-tunable wireless access scheme based on optoelectronic oscillating technology is proposed and experimentally demonstrated. By using this scheme, the frequency of the transmitted wireless signals can be tuned by adjusting the wavelength of the input light. The 1.25 Gb/s on-off keying signals with the carrier frequency of 8–14.5 GHz are generated and transmitted through a radio over fiber link. The envelope detecting technique is employed in the receiver to support the down-conversion and demodulation. Electrical local oscillators are not required in the transmitter and receiver end, which simplifies the system structure and lowers the cost.
