Abstract

A received is disclosed that is capable of improving reception sensitivity while avoiding an increase in circuit scale. The receiver includes: a multi-phase local oscillation signal generating section that generates a plurality of local oscillation signals of different phases; a phase selection signal generating section that generates a phase selection signal used to select a baseband signal of a predetermined phase based on a detection result of a reception level of a high-frequency signal; and a frequency converter that frequency-converts the high-frequency signal based on the plurality of local oscillation signals, that generates a plurality of baseband signals of different phases, and that selects a baseband signal from among the plurality of baseband signals based on the phase selection signal.

First claim

The invention claimed is:

1. A receiver comprising:
a multi-phase local oscillation signal generator that generates plural pairs of local oscillation signals of different phases;
a phase selection signal generator that generates a phase selection signal used to select a baseband signal of a predetermined phase, the phase selection signal being adjusted so as to increase a reception level of a high-frequency signal; and
a frequency converter that frequency-converts the high-fr…
