Abstract
The optical fiber is well adapted to pass multiple wireless signals having different carrier frequencies by using radio over fiber (RoF) technique. However multiple wireless signals which have the same carrier frequency cannot propagate over a single optical fiber, such as MIMO signals feeding multiple antennas in the fiber wireless (FiWi) system. A novel optical singlesideband frequency translation (OSSB-FT) technique is proposed to solve this problem. In this paper, three wireless MIMO signals are designed to transport over a 20 km standard single mode fiber (SMF) using the OSSB-FT technique by one optical source. Each wireless MIMO signal is with a 2.44 GHz carrier frequency, 1 Gb/s data rate, and 16 quadrature amplitude modulation (QAM). The crosstalk between the wireless MIMO signals is excluded, since each wireless MIMO signal is carried on a specific optical wavelength.
