(These three channels were referred to as “Perch” in previousversions of the W-CDMA standard and option SMIQB45)A (downlink) signal containing the following components is generated:• P-CCPCH (-20 dB)• P-SCH (-14 dB)• S-SCH (-14 dB)The SCH components are generated with double amplitude for better distinction against PCCPCH.Sequence length = 1Filtering: root cosine (roll-off = 0.22), impulse length = 32, oversampling = 8Data source: PRBS23No superimposed impairments active1125.5555.03 2.219E-9
