WebWCDMA is a step further in the CDMA technology. It uses a 5 MHz wide radio signal and a chip rate of 3.84 Mcps, which is about three times higher than the chip rate of CDMA2000 (1.22 Mcps). The main benefits of a wideband carrier with a higher chiprate are: • Support for higher bit rates • Higher spectrum efficiency thanks to improved phonology articleWebWCDMA uses a fixed transmission chip rate of 3.84Mcps in order to approximately use the 5MHz 9. frequency bandwidth of the channel. ... If every bit of information is multiplied by the spreading code with a chip rate of 3.84Mcps, it means that the bandwidth of the information signal is spread along the bandwidth used by the chip ... phonology anthropology definition

"WebThe chip rate of WCDMA is 3.84 Mcps. Thus, the occupied bandwidth after the RC ﬁlter is 1.22 × 3.84 = 4.68 MHz. If oversampled by a factor of 4, the rate is 4.68 × 4 =15.36 Mqcps. 2.2.5 Multipath Propagation.
