Spread Spectrum and CDMA Techniques


Cellular Mobile Communications





This comprehensive two-day course will cover principles, technologies, system architectures, and standards mainly for cellular applications and expected future standard UMTS. Emphasis will be on applications in present second generation of mobile terrestrial and satellite and future third generation wide band cellular systems. Wireless Local Loop will also be included. Full understanding of cellular concept, system dimension, techniques currently used for capacity enhancements and their tradeoffs. Spread spectrum techniques, and their applications as access schemes, performance in fading channels, transmitter/receiver architectures design option, role of different diversity schemes, and available performance optimisation techniques. The course will provide a thorough review of standardisation activities and available options for UMTS.

THE LECTURER - Dr Rahim Tafazolli B.Sc, M.Sc, PhD

Dr Rahim Tafazolli is a Reader and Head of Mobile Communications Research Group which covers both Terrestrial and Satellite Mobile Communication Systems and is the largest mobile  research group in the UK. His expertise covers both air-interface and networking for mobile systems. He is currently researching on GSM, IS-95, DECT, UMTS and satellite PCN as well as channel characterisation in collaborations with UK, European and USA companies. Dr Tafazolli has lectured and carried out a number of consultancies on these systems and particularly CDMA to a number of mobile companies. He has also published more than 100 technical papers to international workshops, conferences and journals and currently holds 8 patents in the field of mobile communications.
