Appliqueing IMT-2000 features onto Globalstar

Abstract

The IMT-2000 process of the ITU is intended to provide standardized ways of providing high data rate and multimedia services to the wireless user. The cdma2000 proposal for a 3rd generation terrestrial standard is a way of providing these services in a backwardly compatible and evolutionary way for the IS-95 user. The Globalstar LEOS MSS system uses waveforms and procedures derived from IS-95. Our purpose in this paper is to show that many of the features of cdma2000 can be appliqued onto the Globalstar system in an evolutionary way that achieves backward compatibility.
