Simulation tool and rapid prototyping for CDMA2000

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 tube wave travelling 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 environment is considered, implemented and studied.
