Abstract
A symbol sequence in a received DS-CDMA signal is decoded in an efficient manner in order to reduce the processing needs in a receiver when, e.g., processing acquisition indicators (AI) in a UMTS system. The decoding comprises iterative calculation of a hard-decision vector, using a decision threshold having a value based on the probability of each ternary alphabet element of each symbol in the hard-decision vector.
