RECEIVER AND RECEPTION METHOD

摘要

PROBLEM TO BE SOLVED: To manufacture a pilot aid rake receiver with an inexpensive conjugate pilot multiplier by avoiding the performance of the rake receiver from being lost with respect to a code division multiple access CDMA receiver. SOLUTION: Fingers of a CDMA receiver have N sets of rake receiver fingers 407-1-407-N that output an information transmission signal Ii (n) and a conjugate pilot estimate value Pi (n) corresponding to thereto, N sets of multipliers 502-1-502-N and an N×N switch 500. The N×N switch 500 is placed between the N sets of rake receiver fingers 407-1-407-N and the N sets of multipliers 502-1-502-N and transfers the information transmission signal Ii (n) and the conjugate pilot estimate value Pi (n) from any of the N sets of rake receiver fingers 407-1-407-N to any of the N sets of multipliers 502-1-502-N.
