To research, simulate and understand the physical limitations of wireless high data rate systems. To develop techniques and knowledge to enable efficient solutions to the physical limitations. Generate valuable key inputs to standard committees and to represent the UK at these meetings. Disseminate the information gathered at standards activities. Progress:This project was started three months ago with the appointment of a Post Doctoral Research Assistant. There is also an Earmarked PhD studentship at Bradford. The University's involvement in this project is mainly in the area of channel equalisation.Since a large quantity of research results on adaptive equaliser algorithms and their implementation has been reported in the open literature, a comprehensive literature search has been initiated to extract information vital to this project. A data base has been created to keep track of relevant papers and the search activity continues as a background activity. Preliminary results of the search have led to an equaliser review in which a number of equaliser algorithms will be thoroughly compared on the basis of many factors. As a first step, rate of convergence of LMS and RLS used in a DFE structure under different channel conditions are being estimated by computer simulation. Computer programs for this purposes have been completed. Initially, the effect of synchronisation errors is not taken into account, but as the simulation programs are further developed this will be incorporated. Furthermore, provision has been made for inclusion of power delay profile measurements done at Symbionics once they are available. Work has commenced on theoretical analysis of the steady-state BER performance of a GMSK modem using a DFE in the indoor wireless channel. This allows both Rayleigh and Rician channels. Practical measurements of time delay profile can be incorporated into this analysis, thereby increasing its validity. The draft standard of HIPERLAN defines a450 bit training sequence. Some work has commenced on exploiting this relatively long training sequence for antenna diversity/equaliser complexity tradeoffs.
