Webthe binary value "1" is mapped to the real value –1. The DPCCH is spread to the chip rate by the channelization code C ch,0, while the n:th DPDCH called DPDCH n is spread to the chip rate by the channelization code C ch,n. One DPCCH and up to six parallel DPDCHs can be transmitted simultaneously, i.e. 0 ≤ n ≤ 6. Σ C ch,1 DPDCH 1 β d C ... WebWhat is Wcdma chip rate? The basis for the physical layer of WCDMA is spreading of the data to be transmitted to the chip rate corresponding to 3.84 Mchip/s using channelization codes. It is also responsible for coding, transport-channel multiplexing, and modulation of the radio-frequency carrier.

5.16: 3G, Third Generation- Code Division Multiple Access (CDMA)

In digital communications, a chip is a pulse of a direct-sequence spread spectrum (DSSS) code, such as a pseudo-random noise (PN) code sequence used in direct-sequence code-division multiple access (CDMA) channel access techniques. In a binary direct-sequence system, each chip is typically a rectangular pulse of +1 or −1 amplitude, which is multiplied by a data sequence (similarly +1 or −1 representing the message Webnetworks with data rates up to about 144kbit/s. 3G networks (UMTS FDD and TDD, cdma2000 1x EVDO, cdma2000 3x, TD-SCDMA, Arib WCDMA, EDGE, IMT-2000 …
