Annotation for characteristics section
Attenuation of WCDMA signal (“Powertransferfunction”,
α
WCDMA) is determined by
fCarrier according to 3GPP TS 25.101 (e.g. for WCDMA Band 5-Passband, fCarrier ranges from
826.4 MHz (lowest Tx channel) to 846.6 MHz (highest Tx channel)). HRRC(f) is the transfer func-
tion of the root-raised cosine transmit pulse shaping filter according to 3GPP TS 25.101 with the
following normalization:
