RADIO RECEIVING DEVICE AND ANTENNA VERIFICATION METHOD

摘要

PROBLEM TO BE SOLVED: To provide a radio receiving device and an antenna verification method wherein antenna verification is enabled even if the number of pilot symbols of DPCCH is one.

SOLUTION: A rotation part 110 performs rotation of±π/2 to a CPICH-Ant#2 phase estimation and computes phase estimations in which rotationΨis performed, respectively and which are hypotheses of phase rotation which are used by a base station instrument. An addition part 111 adds a CPICH-Ant#1 phase estimation and a phase estimation output from the rotation part 110. An inner product calculation part 112 computes inner product of a DPCCH pilot-Ant#1 phase estimation and output of the addition part 111. A maximum detection part 113 detects the maximum of computed each inner product value and outputsΨcorresponding to the maximum as a phase rotation estimation used in the base station instrument.
