摘要:
A multipath propagation delay determining means (STU) for determining a power delay spectrum (DPS) of a signal on a plurality of propagation paths within a cell of a CDMA communication system, comprising A/D conversion means for converting a CDMA multipath signal received from at least one antenna (Ant1, Ant2) into a signal (S1, S2) consisting of consecutive radio frames including consecutive time slots with complex pilot symbols and data symbols, demultiplexing means for extracting complex pilot symbols and data symbols from at least two consecutive time slots of each radio frame and for storing them consecutively in memory means; and a searching means (S1...SL) for determining a power delay profile (DPS) on the basis of said extracted and stored complex pilot symbols and said data symbols.
