    Abstract

    We present both OFDM radar and wireless communication experiments with 30-GHz RoF technology using the same experimental set-up. Two of key technologies of a newly developed 30-GHz wideband photoreceiver module and digital pre-distortion techniques allow a high space resolution with high signal-to-noise ratios. From the wireless communication experiment, 14.5-Gbps high data rate up to a distance of 10-m is achieved with a 1×10- 3 bit error rate using single carrier signal, which can be easily switched to a multi-carrier signal system, such as orthogonal frequency-division multiplexing (OFDM). In the OFDM radar experiment (10.1 GHz bandwidth, 1683 subcarriers) including low crest factor OFDM reference signal, highly reflected signals from “known refractors” located at a 5-m distance could be clearly detected.
