WebIn direct sequence spread spectrum technologies such as DSSS and CDMA, it is the number of bits per second (chips per second) used in the spreading signal. A different spreading signal is added... 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…
