Annotation for characteristics section

Attenuation of WCDMA signal (“Powertransferfunction”, α_WCDMA) is determined by

S_ds21(f)H_RRC(f – f_Carrier) ²df

∫

f_Carrieraccording to 3GPP TS 25.101 (e.g. for WCDMA Band 2 Passband, f_Carrierranges from

1852.4 MHz (lowest Tx channel) to 1907.6 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:
