Abstract: The present invention relates to a code division multiple access (CDMA) communication system, more particularly to an arrangement and a method in a receiver (10) to simplify and improve signal processing in the demodulator (11) of the receiver (10) by means of reducing the long term dynamic range of received signals and, thus, reducing the number of bits needed for coding of said signals. This is accomplished by a signal processing means (16) in the signal input paths in front of the demodulator (11), said means (16) including at least an improved digital AGC-unit (161), which scales incoming signal samples to a common and constant power level, and including a subsequent quantizer unit (162), which transforms the scaled signal samples to samples using a reduced number of bits. Due to this, the transmission bandwidth in the receiver unit is reduced and the signal processing in the demodulator is less complex.
