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

In this paper, we have shown that optical code division multiplexing (O-CDMA) systems at 10 Gb/s that can support at least 10 simultaneous users with BER<10-9 can be effectively designed for implementation in real networks. The carrier-hopping prime code is chosen to offer the optimum correlation values and maximum cardinality while providing a satisfactory bit error rate (BER). The encoder design can be advantageous of scalability allowed by increasing the code matrix size and the complementary decoder reduces cardinality limitations.
