Annotation for characteristics section
Attenuation of WCDMA signal (“Powertransferfunction”, α_WCDMA) is determined by
∫∞ Sds21(f )HRRC(f – fCarrier) 2df
∞
f_Carrier according to 3GPP TS 25.101 (e.g. for UMTS-Passband, f_Carrier ranges from 882.4 MHz
(lowest Tx channel) to 912.6 MHz (highest Tx channel)). H_RRC(f) is the transfer function of the
root-raised cosine transmit pulse shaping filter according to 3GPP TS 25.101 with the following
normalization:
∫∞ HRRC(f ) 2df = 1
