Abstract : This paper describes the features of a cdma2000 physical layer compliant library for rapid prototyping and system modelling. References to the standard specifications and to particular CDMA signal transmission scenarios are used to describe the CDMA2000Lib library’s functionality and benefits. Single-pilot signals and signals with multiple code channels are generated, and relative constellation diagrams are shown. A non linear system model, represented by a Traveling Wave Tube Amplifier (TWTA), is implemented and used to study the CDMA signal degradation (in time domain) and to estimate the Error Vector Magnitude (EVM) parameter. A signal transmission on a multipath channel enviroment is considered, implemented and studied.
