Patent ID: 6862314

Claim:
Receiver for detecting information symbols transmitted according to a CDMA technique, according to which CDMA technique the information symbols are spread with different spreading codes and scrambled with different scrambling codes, on the transmission side, the receiver comprising: a plurality of despreading units ( 44 , 45 ) for despreading an input data bitstream with said different spreading codes, said input data being supplied to the despreading units ( 44 , 45 ) by means of a delay line ( 42 , 43 ), and a set of k descrambling units ( 46 , 47 , 48 , 49 ) per despreading unit ( 44 , 45 ), k being an integer larger than 1, respectively k descrambling units ( 46 , 47 , 48 , 49 ) being supplied with the output signal of one despreading unit ( 44 , 45 ); whereby said k descrambling units are supplied with respective ones of k scrambling codes; whereby the output of each despreading unit is divided into a plurality of parallel streams and each one of said parallel streams is passed to a respective set of k descrambling units.
