Correction to “System Design of Gigabit HAPS Mobile Communications”

In the above article
[1]
, there was an incorrect statement on antenna pattern related to (1) in Section III-B. The sentence just after (1) should be read as “where
$\Psi_{b}$
is the half-power beamwidth divided by 2,
$\Psi_{1}=\Psi_{b} \sqrt{-L_{N} / 3}, \Psi_{2}=3.745 \Psi_{b}, X=L_{N}+A \log _{10}\left(\Psi_{2}\right)$
, and
$\Psi_{3}=10^{\left(X-L_{F}\right) / A}$
.” The definitions of
$\Psi_{b}$
and
$\Psi_{3}$
are modified.
