ABSTRACT:
The present invention provides a CDMA receiving apparatus capable of corresponding to the service types of data and system conditions flexibly and efficiently, so as to achieve such processing for electric power control, diversity control and the like, requested to have real-time property. A CDMA signal inputted into a memory is searched by searcher units of each reception processing block. Voice data and low-speed data are demodulated immediately by a finger unit for data field and a finger unit for control field, and combined by RAKE-combining units. Data fields of packet data and high-speed data are accumulated in memories for data field and demodulated by finger units for data field successively based on path information stored in memories for path information.
