Influence of Chip Frequency on Characterizing Radio Channels for Rake Receiver Fingers for CDMA Systems in Microcellular Environment

摘要

The new frequency bands that will be allocated to W-CDMA cellular networks might open the possibility to use higher bandwidths than the 5 MHz specified in 3GPP. In this paper the temporal channel properties, i.e., power delay profile, in terms of number of Rake receiver fingers and their characteristics, are analyzed for 5, 10, 20, and 30 MHz bandwidths. The lower bandwidth impulse responses are obtained by filtering measurement results obtained with a channel sounder having a bandwidth of 30 MHz.
