Abstract:
A receiving apparatus comprising: a first mixing unit to output first and second mixed signals each having a first frequency that is a frequency difference between a received signal and a first local oscillator signal, the first and second mixed signals having phases substantially orthogonal to each other; a phase control unit to output second and third local oscillator signals each having a second frequency, the second and third local oscillator signals having a phase difference from each other corresponding to a phase difference between the first and second mixed signals; and a second mixing unit to add a signal obtained by mixing the first mixed signal and the second local oscillator signal, and a signal obtained by mixing the second mixed signal and the third local oscillator signal, to output an intermediate frequency signal having an intermediate frequency that is a difference between the first and second frequencies.
