<p>Apparatus and method for closed-loop power control in mobile satellite communication system, which can compensate round trip delay. The apparatus for closed-loop power control includes the means of; a)converting power control order from base earth station into power control step; b)measuring channel change rate from power of pilot channel; c)making tab coefficient using said channel change rate; d) compensating channel change due to loop delay using power control step; and e)renovating received signal power using said power control step.</p> |
