Abstract
In this paper, several multiple-input multiple-output (MIMO) techniques
are studied for OFDM/A systems which have antennas connected to the base
station with radio over fiber (RoF). The delay effects caused by the optical
fibers on the fixed-beam transmit beamforming are studied via Monte Carlo
simulations. Also the effect of combining RoF with other MIMO techniques in
OFDM/A systems, like spatial multiplexing, space-time coding, and receiver
beamforming, h discussed. The results indicate that for phase shift
differences lower than those corresponding to a 1 m unevenness in the fiber's
length, RoF does not significantly decrease the performance of an OFDM/A
system with fixed transmit beamforming, and with other MIMO techniques, the
effect of employing RoF is negligible. (14 refs.)
