Abstract
A method and a signal evaluator determine a noise part in a signal mix of a reception signal of a CDMA receiver. An additional spread code with which the reception signal is despread is formed at the reception side in addition to the individual spread codes of the individual CDMA connections. The resulting reference signal is subsequently evaluated and the noise part is determined from the reference signal.
