WebCDMA systems use a signal fast chip rate for spreading the spectrum. It has a high time resolution, due to which it receives a different signal from each path separately. The … WebJul 13, 2011 · In general, CDMA is a multiple access technology that was introduced after the TDMA and FDMA. CDMA serves the different users with separate code sequences, while there are other multiple access technologies that use time, frequency, space, and polarisation for user access separation.

WebCDMA (Code Division Multiple Access) is a communication technique that allows multiple users to communicate simultaneously over one frequency. This is achieved through the use of spreading codes, whereby a single data bit is "spread" over a longer sequence of transmitted bits. WebCode division multiple access (CDMA) is a form of spread spectrum communications that is being used for, among other applications, some second-generation cellular phone systems (others use TDMA). The method is also known as S-CDMA, where the S stands for synchronous. S-CDMA is one of the advanced upstream options specified for DOCSIS 2.0.
