| 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
