Cdma Receiving Device, and Path Searching Method
摘要:
Upon receiving an instruction to open a radio link, a path management unit (154) designates, for one radio link, a spreading code number for a common pilot channel and a spreading code number for an individual channel to a spreading code generator (153). The spreading code generator (153) generates spreading codes for the respective channels and sends them to a correlator (151). The correlator (151) outputs the correlation values between a reception signal (IQ signal), the common pilot channel, and the individual channel. A delay profile unit (152) generates delay profiles concerning the common pilot channel and individual channel by in-phase-adding and power-adding correlation values from the correlator (151) for each channel. The path management unit (154) detects path timings from both the delay profiles concerning the common pilot channel and individual channel, and assigns path timings TM to finger units (141) in descending order of reception power. This improves the stability of reception quality.
