A noise suppression apparatus comprising: a complex signal generation unit configured to convert an intermediate frequency signal into a complex signal having a real part and an imaginary part, the intermediate frequency signal being obtained by frequency-converting a reception signal; a noise detection unit configured to detect whether or not variation in level of the complex signal is greater than a predetermined threshold value, to detect generation of noise; and a noise suppressing unit configured to suppress level of the complex signal if the variation in level is greater than the predetermined threshold value.
