摘要:
A signal reception apparatus for DS-CDMA communication system having a complex matched filter for despreading a received signal into I-and Q-components Di and Dq of despread signal. Di and Dq are input to a path selection portion 13 for extracting a phase error in a pilot symbol block of the despread signal. A phase compensation signal is calculated according to the phase error in the portion 13. An information symbol is compensated according to the phase compensation signal. An electrical power is calculated from an average of the phase compensation signal of several slots for selecting paths to be received. The selected paths are combined with phase synchronized by a rake combiner 14.
