We experimentally investigate the wireless channel characteristics of 2×2 60-GHz MIMO OFDM RoF system with 3.5-m wireless distance. With lattice-reduction-aided detection, the achievable data rate can be improved from 0.58Gbps to 12.61Gbps for the worst case.
We propose a simple 60GHz RoF system using a single-electrode MZM with transmission distance improvement from 3km to 10km. With beat noise mitigation algorithm, SNR can be improved by up to 5.5dB.
We demonstrate 1.1-Gb/s visible light communication (VLC) employing carrier-less amplitude and phase modulation (CAP) and a commercially available phosphorescent white light emitting diode (LED). Optical blue filtering, precompensation, and decision feedback equalization are used to compensate the frequency response of the phosphor-based white LED. Various modulation orders of CAP signals are investigated...
This paper reviews 60-GHz radio-over-fiber systems employing optical frequency multiplication and adaptive OFDM signals with multi-level modulation formats to achieve an ultra-high data rate of up to 32.65 Gbps within the 7-GHz license-free band.
We employ 2×2 MIMO spatial multiplexing to double the spectral efficiency of a 60GHz RoF system. A 27.15-Gbps 16-QAM MIMO signal with 3m wireless transmission is experimentally demonstrated within 7-GHz license-free spectrum at 60 GHz.
We experimentally demonstrated an adaptive I/Q imbalance correction scheme to compensate I/Q-imbalance. With I/Q correction, a 32.65-Gbps OFDM signal at 60 GHz within 7-GHz license-free band is successfully generated and, following 25km SMF transmission, negligible power penalty is observed.
