Chip rate in wcdma

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. WebSep 25, 2010 · The chip rate of a WCDMA system is 3.84 Mcps. Spreading factors range from 256 to 4 in the up link. Thus, the respective modulation symbol rates vary from 960K symbols/s to 15K symbols/k. 1. The modulation symbol rates refers to the data signal, before it's being spread?
