Abstract:
1. A reception apparatus, comprising: an intermediate frequency converter configured to convert a plurality of transmission signals in different frequency bands into a plurality of intermediate frequency signals having different intermediate frequencies, the plurality of transmission signals each being obtained by demodulating a spectrum-spread signal; an analog-to-digital converter configured to discretize the plurality of intermediate frequency signals and output a plurality of discretization signals; a plurality of noise removing units configured to remove a noise other than a normal thermal noise included in the plurality of discretization signals from the plurality of discretization signals; and a controller configured to detect the noise included in the plurality of discretization signals and set assignment of the plurality of noise removing units to the plurality of discretization signals, wherein the assignment is performed based on detection of frequencies of the plurality of discretization signals having amplitude greater than or equal to a predetermined value.
