Overview
The WCDMA digital upconverter (DUC) and digital downconverter (DDC) reference design demonstrates how system architects and hardware designers can accelerate the design of DUC and DDC functions for WCDMA basestations using Altera® devices, tools, and intellectual property (IP). The system design challenges associated with WCDMA DUC and DDC designs are illustrated and the companion reference designs act as a demonstration of how to overcome these challenges while achieving an optimized and cost-effective hardware implementation.
Features
- DSP Builder-based design methodology to significantly reduce the development time
- Multichannel filter design techniques to achieve cost-effective solutions
- Highly parameterizable IP MegaCore® functions to further reduce development time
- Support for multiple transmit and receive antenna configurations
- Easily modifiable to support scalable channel bandwidths and macro and picocell base transceiver
station (BTS)
- Compliant with the 3GPP/UMTS/Release 6 standards
Demonstrated Altera Technology
