ground without any mountains, buildings, tunnels, trees, etc. It would be very easy to plan a CDMAnetwork of base stations. There would only be direct paths to any receiving subscriber units (phones). Since we do not live in a perfect world, transmitted signals from Base Stations will reflect off of obstructions such as mountains to create a great number of signal paths, also known as multipath. ...

Berkeley Varitronics Systems has developed three CDMA Pilot PN scanners that are currently being used to diagnose and remediate problems in CDMA networks. This article presents some of the problems that have been found and diagnosed with pilot scanners. Other potential problems in CDMA networks are addressed, and CDMA Field tools capable of diagnosing these potential problems are introduced. ...

Medical CT, MRI, and other scanned images can be treated as 3D data sets. Modern computers and GPUs provide substantial resources to process these 3D datasets in real time for faster diagnosis and improved visualization techniques. The suitability of various GPU products for medical imaging is not obvious from common benchmarks, so medical benchmarks are required to understand which products are ...

Universal Serial Bus (USB) is an extremely popular serial interface that makes adding peripherals to your computer incredibly easy.
A USB peripheral simply plugs right into the port and works. You don’t need to install a card; you don’t even need to turn off your computer. Because USB configuration happens automatically, built-in USB means you don’t have to fiddle with drivers and software when ...

The use of CDMA field testing equipment, introduced in Part I, data collected by the equipment in the field and analysis is presented here in Part II. CDMA system parameters and performance are measured primarily by signal to noise ratios (e.g. Ec/Io) instead of signal strength (dBm) and frequency re-use has been replaced by code re-use ...
