<p>Despreading of the received signal (on 101) in a CDMA system is provided using code coefficient sequences which are derived (in 104) from those utilized by the system users to encode their respective symbols. Each derived code coefficient sequence (on 103) is a function of the correlation between a different user's code coefficient sequence (105-1...105-n) and the code coefficient sequences of all other users. Advantageously, this technique substantially reduces interference effects and is suitable for use in the despreader (102) of differentially or non differentially coded CDMA systems. <IMAGE></p> |
