When mobile-to-base links cannot be precisely coordinated, particularly due to the mobility of the handsets, a different approach is required. Since it is not mathematically possible to create signature sequences that are both orthogonal for arbitrarily random starting points and which make full use of the code space, unique "pseudo-random" or "pseudo-noise" sequences called spreading sequences are used in asynchronous CDMA systems. A spreading sequence is a bin… 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.

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. 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.
