Software delivers accurate noise simulation

Article Abstract:

Cadence Design Systems' SpectreRF software offers a precise modeling of frequency conversion using a periodically changing linear representation. The San Jose, CA-based company's software package offers an improvement from the conventional SPICE-based simulation systems that tend to produce a linear, non-changing noise simulation model, an improper simulation of frequency-conversion circuits, including such devices as mixers. Cadence's SpectreRF, by using advanced versions of RF-simulation algorithms, is able to recreate such effects as noise folding.

Software maps RF propagation

Article Abstract:

MapInfo Corp of Troy, MI, has developed a Windows-based software that helps model RF propagation when planning a wireless system. Called deciBel Planner, it runs on a standard personal computer with Windows 95 or Windows NT. The software predicts outdoor RF propagation effects based on high-resolution terrain models or data recovered from a Global Positioning System (GPS) receiver. deciBel Planner also provides a variety of surface analysis tools to support the propagation process.
