Spread Spectrum CDMA System Design and Comparative Testing on Two Continents

Abstract

Spread spectmm techniques have been employed for over half a century to counter the effects of strong in-band interference, usually intentionally transmitted by hostile sources. Only recently, however, has the commercial and consumer communication industry become aware of the potential advantages of this technology for providing wireless multiple access to large populations of users employing scarce bandwidth resources in regions with difficult propagation environments.
