Abstract

The invention relates to a method for decoding a spread-coded signal. The aim of the invention is to decode a received bit sequence (s(t)) of a first transmission channel (A) which is based on a spread code of a data sequence (di(t)). To this end, said data sequence is correlated with a truncated de-spreading sequence (c'i(t)) derived from the first spread sequence (ci(t)) and then integrated. Additionally, a correction is carried out to compensate for the influence of the second transmission channel (B) on the first transmission channel (A) depending on the knowledge of at least one second transmission channel (B) via which bits are transmitted that are encoded by a second spread sequence that is complementary to the first spread sequence (ci(t)).
