- W1992567289 abstract "This work is about the effect of frequency selectivity on multi-carrier wideband signals in two different environments; indoors and outdoor to indoor. The investigation was made using measurements carried out with a sounder with a 300 MHz bandwidth. The main part of this work is to evaluate the contribution of several related parameters; frequency selective fading, coherence bandwidth and delay spread on the frequency selectivity of the channel. A description of the sounder parameters and the sounded environments are given. The 300 MHz bandwidth is divided in segments as small as 60 kHz to perform the evaluation of frequency selective fading. Sub channels of 20 MHz for OFDM systems and 5 MHz for WCDMA were evaluated. Graphics are provided for a number of bands, parameters and locations in the different environments. It is also shown the variation of the signal level due to frequency selective fading. The practical assumptions about the coherence bandwidth and delay spread are reviewed and a comparison is made with actual measurements. Statistical analysis was performed over some of the results." @default.
