Personal VSAT terminals based on synchronous CDMA spread spectrum technique
Abstract
Band Limited Quasi Synchronous (BLQS) Code Division Multiple Access (CDMA) based Very Small Aperture Terminals (VSATs) are presented along with a suitable network architecture. The terminals have been termed Personal VSATs (PVSATs) due to the small physical dimensions and the great flexibility provided by the fully digital concept. BLQS-CDMA is a new satellite multiple access technique providing similar spectral efficiency to Time Division Multiple Access (TDMA) without renouncing the advantages of CDMA with respect to power flux density, off beam emission, power efficiency, security, and flexibility.
