WebThe spread function for CCK is chosen from a set of M nearly orthogonal vectors by the data word. CCK uses one vector from a set of 64 complex (QPSK) vectors for the symbol and thereby modulates 6 bits (one of 64) on each 8 chips spreading code symbol. Two more bits are sent by QPSK modulating the whole code symbol. WebUMTS uses variable spreading and power levels to provide different user data rates. In FDD mode 10 msec frames are used The number of chips per bits is called the Spreading Factor (SF) and define the data service required for the user:the data service required for the user: Tbit = SF x Tchip For UMTS: Bit Rate x SF = 3.84 Mchips/s (Chip Rate)
