A new method for generating families of ternary spreading sequences is presented. The sequences have aperiodic zero correlation zones and large families are created for a specific sequence length. The sequences are proposed as spreading sequences to provide high capacity and cancel multipath and multiple access interference (MAI) in a single carrier (SC) or(More)
We present a novel neural network method for the analysis and interpretation of data that describes user interaction with a training tool. The method is applied to the interaction between trainee network managers and a simulated network management system. A simulation based approach to the task of efficiently training network managers, through the use of a(More)
This paper presents a study of the use of wikis to support online group projects in two courses at the UK Open University. The research aimed to investigate the effectiveness of a wiki in supporting (i) student collaboration and (ii) tutors' marking of the students' collaborative work.
