Abstract :
This paper presents an overview of the research work carried out by the faculty members and students of the Delft University of Technology (TU Delft), The Netherlands in the field of code division multiple access. They have investigated CDMA systems considering direct sequence (DS), slow frequency hopping (SFH), hybrid SFH/DS, hybrid CDMA/inhibit sense multiple access (ISMA), multi-carrier (MC)-CDMA, interference cancellation, dynamic code channel allocation, synchronization, receiver structure and overlay CDMA/TDMA systems for macro-, micro- and pico-cellular systems as well as for land mobile satellite systems. The effect of forward error correction (FEC) coding and of diversity techniques on CDMA systems performance is also analyzed. Computer simulation has been performed to verify the basic assumptions, such as approximating by multi-users interference by a Gaussian random variable, in the analysis. Results of these investigations are summarized and discussed
