Abstract

This paper derives upper and lower bounds on the capacity of the
multiple-input single-output free-space optical intensity channel
with signal-independent additive Gaussian noise subject to both an
average-intensity and a peak-intensity constraint. In the limit
where the signal-to-noise ratio (SNR) tends to infinity, the
asymptotic capacity is specified, while in the limit where the SNR
tends to zero, the exact slope of the capacity is also given.

Keywords

Average- and peak-power constraint, channel capacity, direct
detection, Gaussian noise, infrared communication, multiple-input
single-output (MISO) channel, optical communication.
