Open Access research with a real impact on health...

The Strathprints institutional repository is a digital archive of University of Strathclyde's Open Access research outputs. Strathprints provides access to thousands of Open Access research papers by Strathclyde researchers, including by researchers from the Physical Activity for Health Group based within the School of Psychological Sciences & Health. Research here seeks to better understand how and why physical activity improves health, gain a better understanding of the amount, intensity, and type of physical activity needed for health benefits, and evaluate the effect of interventions to promote physical activity.

Abstract

Using a 4-node testbed at 253 Gchips/s, the capability of fast frequency-hopping time-spreading OCDMA to provide differentiated service by varying the code weight is demonstrated. Bit error rate variation of five orders is obtained. A proposed novel scheme enables variation of code weight, and hence service guarantees, on a per-bit basis.
