Abstract:
1. A method for receiving a data stream transmitted via at least one data transmission path comprising the steps of: receiving the data stream with a receiver; determining a power delay profile for the received data stream, the power delay profile indicative of peak values of received power in a plurality of transmission path positions; detecting at least one peak value in the power delay profile with a peak detector; determining a data transmission path profile based upon the at least one peak detected, the data transmission path profile comprising at least one shadow transmission path, wherein the data transmission path profile is determined by counting the number of occurrences of detected peaks in the plurality of transmission path positions over a predetermined period, by comparing the number of occurrences counted to a predetermined threshold number of occurrences, by setting to zero each of the plurality of data transmission paths that do not exceed the predetermined threshold, and by determining the data transmission path profile based upon the plurality of data transmission paths that are not set to zero; suppressing the at least one shadow transmission path in the data transmission path profile; and setting data transmission paths in the receiver based upon the suppressed data transmission path profile.
