摘要: The invention relates to a multipath propagation delay determining means (STU, FIGS. 6, 7 ) for power spectrum (DPS) of CDMA signal transmission between base station (BS) and mobile (MS) on plurality paths (P 1 , P 2 within cell (CL) communication system, comprising an A/D conversion (A/D) converting analog (S S received from at least one antenna (Ant Ant said into digital consisting consecutive radio frames (RF . RFn) including time slots (TS TSm) with complex pilot symbols (PSi) data (Pdi), demultiplexing (PI-DEMUX) extracting (PDi) two (TSk−1, TSk, TSk+1) each frame (RFn) storing them consecutively in memory (BUF) thereof; searching SL) profile (DPS, DPS FIG. 14 (Ant. Ant. the basis extracted stored (PSi, PDi).
