High-Frequency System Designers Can Now Design to Latest 3G Specifications

USA : Applied Wave Research announced the release of a code division multiple-access 2000 (cdma2000) test bench for the company's Visual System Simulator(TM) (VSS) design suite. The new test bench is designed for radio-frequency (RF) system engineers who need to evaluate the impact of RF link impairments on frame error rate (FER), bit error rate (BER), symbol error rate (SER), and other metrics.

The VSS cdma2000 test bench modular design and intuitive interface offers an unprecedented flexibility in configuration and ease-of-use. This enables RF systems groups to be self-sufficient by providing a "canvas" to quickly and easily make changes and/or add functionality. The VSS design suite offers a rich set of behavioral RF models and integration with AWR's Analog Office(TM) circuit design software and popular industry instrumentation. This provides engineers with a unique, single simulation environment that can be used to efficiently analyze RF impairments without having to switch between tools.

"The VSS cdma2000 test bench is the latest software innovation in AWR's continuing commitment to provide engineers with effective, easy-to-use, integrated tools for the generation of the complex modulated signals needed to design next-generation communications products," said Joel Kirshman, AWR market segment manager for system simulation.

The VSS test bench consists of transmit and receive blocks and supports variable frame sizes, data rates, and multiple channels including fundamental and supplemental traffic, pilot, as well as an orthogonal channel noise simulator (OCNS). All the bit-level functions, framing, cyclical redundancy code (CRC), forward-error correction (FEC), interleaving, Walsh and quadrature spreading, and modulation for forward and reverse link operation are included.

About Visual System Simulator

Visual System Simulator (VSS) is a comprehensive software suite for the design of complete, end-to-end communications systems. The VSS technology uses an advanced, time-based simulation engine coupled with a circuit simulation tool that enables systems and circuit designers to work together within a single environment to perform interactive, top-down analysis of analog and digital communications systems. VSS software effectively gives the entire engineering organization the "big picture," including the RF impairments in the presence of complex modulated signals. The solution reduces time-to-market by providing a single integrated environment wrapped in an intuitive, easy-to-use interface. VSS technology enables designers to easily make critical system performance measurements, accurately analyze the impact of RF components on modulated signals, and make cost effective trade-offs between system and circuit specifications.
