Goals

To help the US cellular communications industry test the wideband CDMA components (cdma2000 and W-CDMA systems) of the IMT-2000 family of standards for third-generation wireless systems over different traffic and wireless channel quality conditions. To facilitate transmission of video signals over 3G wireless systems.

Technical Approach

Developed SPW models for the forward link, reverse link, and multi-carrier mode of the cdma2000 system Measured the performance of the cdma2000 system over different ITU channel models and in face of interference from other users communicating multimedia information Developed a partitioning method and a multi-priority transmission method to send video over 3G wireless systems

FY02 Plans

Provided industry customers with as needed consulting to understand and use the SPW cdma2000 models distributed on our web site. Wraped this project up
