| Abstract | This thesis presents the research carried out in order to analyze the performance of a
Direct Sequence (DS) Spread Spectrum (SS) Code Division Multiple Access (CDMA) technique
for application in Cellular Mobile Radio Systems. The performance of a CDMA cellular mobile
radio system in a fading and shadowing channel depends upon the cell topology employed. The
performance of a wideband and a narrowband CDMA cell topology is investigated by applying
an accurate mobile radio channel model. This mathematical model takes into account the
influence of multipath fading and shadowing observed in a physical mobile radio channel and this
provides an accurate measure of the capacity performance of a cellular mobile radio system.
Three different cellular mobile radio environments are considered and comparative performance
results are presented under different degrees of fading and shadowing conditions. The extent of
fading and shadowing are defined over a range of parameters considered relevant to a mobile
cellular CDMA system. For this reason the results presented constitute a feasibility study. The
performance of two deterministic pseudorandom code sequences for use in a narrowband CDMA
cellular mobile radio system is assessed. The performance of the proposed Qualcomm system has
been evaluated under different mobile radio channel conditions. Finally, capacity and spectral
efficiency performance results are presented for the CDMA cellular mobile radio system and are
compared to the GSM standard. |
