SMIQ Digital Standard W-CDMA (NTT DoCoMo/ARIB 0.0)A mobile station transmitter in line with the ARIB standard is simulated in the UP_IQ_MULT mode.Separate channel types and data sources for I and Q are available in the multiplex mode.Fig. 2-89Uplink signal generation with IQ multiplex and several code channelsAccording to ARIB, DPDCH (Dedicated Physical Data Channel) and DCPCH (Dedicated ControlPhysical Channel) are available as channel types in the uplink. The data rate for modulation data(framed data) of the DPDCH can be selected (16, 32, 64, to 1024 ksymbol/s).The modulation data are not calculated in real time in SMIQ. On the user request, a W-CDMA chipsequence is calculated (STATE = ON) and then stored in the data memory of the data generator (optionSMIQ B11). The sequence length is settable (SEQUENCE LENGTH [FRAMES]), the maximum possiblelength depends on the memory capacity of the data generator.A special multicode mode is available (MULTICODE) for LINK DIRECTION/MULTIPLEX DOWN andUP modes. The data fields Pilot and TPC have the same settings and are spread with the samespreading codes of the MASTER CHANNEL.1125.5555.03 2.151E-9
