CoWare SPW Advances Verification of 3G Wireless Modems; New HSDPA Models in 3GPP Library Reduce Design Risk for High-Speed Cellular Modems.

SAN JOSE, Calif. -- CoWare(R) Inc., the leading supplier of system-level electronic design automation (EDA) software and services announced the availability of the High Speed Downlink Packet Access (HSDPA) models in 3GPP Library for its SPW signal processing design solution. Wireless system designers are able to reduce their specification risk by up to 70%.

"Designing an HSDPA system requires a myriad of system performance simulations," said Dr. Ahmad Vafaei, Senior Staff Engineer, InterDigital Communications Corporation. "We have been using CoWare's HSPDA Library as a reference tool for the 3GPP Release 5 standard. Having an executable reference for 50% of the modem functionality lets us focus on the differentiating components of our HSDPA algorithms."

"CoWare's wireless design solution goes beyond the proof of concept demonstrations other ESL solution providers are offering," said Johannes Stahl, Director Marketing, CoWare. "Our experienced team of wireless design experts continues to deliver detailed, high-quality libraries in lock step with the published standards. Whether you design a particular modem or you are working on software-defined radio, CoWare has the wireless models you need."

HSDPA - Complex, Adaptive Modulation and Coding, Hybrid ARQ

HSDPA delivers high data rates according to the transmission conditions by using adaptive modulation and coding (AMC) schemes. These cover a wide dynamic range in order to cope with the varying downlink radio and channel quality conditions at the handset. HSDPA adapts to these conditions by modifying the effective code rate, the modulation scheme, the number of codes used and power per code. The Hybrid ARQ (H-ARQ) mechanism is used in HSDPA to reduce the delay and increase the efficiency of the retransmitting data. Developing HSDPA receivers, which exhibit the desired performance using AMC and H-ARQ under varying channel conditions, is a design problem with an order of magnitude more scenarios to consider than the static modulation schemes used in previous 3GPP standards.

SPW Libraries Speed HSDPA Design

CoWare SPW is a complete platform for design and verification of DSP algorithms. Its up-to-date communications and multimedia source code libraries are transparently accessible, providing unmatched value for standards explanation and design. The 3GPP library is Release 5 compliant with the newly-added executable end-to-end system models of the HSDPA standard. Using the library, system engineers can rapidly create an accurate model of the system, incorporate their differentiating components, and then simulate the system under different scenarios to optimize the system performance. Leveraging SPW's high simulation speed, users can now explore many system options. And, with source code delivery and powerful PolyModel, designers can use the library as a starting point for detailed fixed-point design. Because the SPW HSDPA library was developed from active participation in the standardization process and with many years of experience developing 3G UMTS/WCDMA models, second-guessing of written standards proposals is eliminated.
