The Globalstar Cellular Satellite System

Fred J. Dietrich, Life Senior Member, IEEE, Paul Metzen, and Phil Monte

Page 935.

Abstract:

In this paper, the Globalstar cellular-telephone satellite system is described, including its use of code-division multiple access (CDMA) as the basic modulation scheme. Use of diversity for signal quality as well as power control is described. Development of the complex array antennas for L-band S-band communication with the hand-held radios is described in detail.
