Chip rate in wcdma
WebThe WCDMA air interface is a direct spread technology. This means that it spreads encoded user data at a relatively low rate over a much wider bandwidth (5 MHz), using a … WebThe chip rate in WCDMA is 3.84Mcpsleading to a carrier bandwidth of5MHz. This chip rate gives the chip duration of0.26 s, so the WCDMA receiver can resolve and combine the multipath components with time difference of larger than0.26 s. WCDMA uses two code types; Spreading code or Channelisation code which

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 WebWCDMA (Wideband Code Division Multiple Access) is the radio access scheme used for third generation cellular systems that are being rolled out in various parts of the ... The chip rate may be extended to two or three times the standard 3.84 Mcps to accommodate data rates higher than 2 Mbps. The 200 kHz carrier raster has been chosen to
