Attenuation of WCDMA signal (“Powertransferfunction”, α
WCDMA
) is determined by
f
Carrier
according to 3GPP TS 25.101 (e.g. for UMTS-Passband, f
Carrier
ranges from 2112.4 MHz
(lowest Rx channel) to 2167.6 MHz (highest Rx 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
