Abstract :
The renewed interest in the application of the spread-spectrum techniques such as CDMA to cellular mobile radio systems, in both the US, and within Europe through the RACE II and UK DTI/SERC LINK programs continues to gather momentum. To this end, an analytical performance model has been developed in order to provide a greater insight into the operation of this technique, in particular the sensitivity of the bandwidth efficiency of the network to the form of diversity signal processing used in the mobile transceiver. This theme is continued with an investigation of the wideband channel characteristics of an urban service area. Results are presented relating the statistics of the RAKE receiver branches to the spreading bandwidth used
