Abstract

The invention relates to a receiving method and a receiver using the method. An adapted filter (208) has a sample sequence of predefined length of a received signal. The sample sequence is decorrelated in the adapted filter (208) with a spreading code received from a code generator (210) to form a decorrelation symbol. The sample sequence is processed stepwise onward by sample and the sample sequence is decorrelated at each step. The decorrelated symbols are combined in a combiner (222) for signal detection preferably utilizing an impulse response profile of an impulse block (314).
