<p>The invention relates to a method for determining strength of co-channel signals, and a receiver utilizing the method. The training sequences of the signals to be received are classified into subsets (21), and a channel estimate (22) related to the signal is formed by comparing the training sequences of the received signal to the training sequences of the subset signals. By means of the channel estimate, a strength estimate (23 - 24) is formed for each received signal, the estimate being used to arrange the received signals (27) according to their strength. When the signal strengths are known, it is possible to decrease the effect of the interference signals on the signal to be detected. In a diversity receiver, a correlation result can be formed of the channel estimates of the signals of each subset, excluding the signal to be detected, the result being used in interference elimination.</p> |
