Abstract

This paper provides several asymptotic capacity results for the
multiple-input multiple-output free-space optical intensity channel in
the regime of high signal-to-noise ratio (SNR). For the case where the
channel matrix has full column rank, the asymptotic capacity is
derived assuming a peak-power constraint on each transmit antenna, or
an average-power constraint on the total power across all transmit
antennas, or both. For multiple-input and single-output channels, the
asymptotic high-SNR capacity is derived when either only the total
average power is constrained, or only the per-antenna peak power is
constrained, or both but with the average-power constraint being
sufficiently loose.
