CDMA receiver, and searcher in a CDMA receiver |
摘要 |
In a searcher of a CDMA receiver comprising an array antenna, a voltage profile generation portion performs correlation computations of received signals for each antenna element and generates received signal voltage profiles; a phase difference estimation portion uses sample data from each voltage profile at the same time to perform correlation calculations among antenna elements and estimates the phase difference among antenna elements at the above time, and similarly estimates the phase differences among antenna elements at each time. An in-phase synthesis portion uses the phase difference estimate at a prescribed time to coordinate the phases of voltage profiles for each antenna element at the above time and performs synthesis, and similarly coordinates the phases of each antenna element voltage profile at other times and performs synthesis; and, a path detection portion detects the path timing of multiple paths based on the synthesized profile obtained by the in-phase synthesis portion.
