RECEPTION APPARATUS

摘要

A reception apparatus includes an intermediate frequency converter, an analog-to-digital converter, a plurality of noise removing units, and a controller. The intermediate frequency converter converts 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 spectrum spread signal. The analog-to-digital converter discretizes the plurality of intermediate frequency signals and outputs a plurality of discretization signals. The plurality of noise removing units remove a noise other than a normal thermal noise included in the plurality of discretization signals from the plurality of discretization signals. The controller detects the noise included in the plurality of discretization signals and sets assignment of the plurality of noise removing units to the plurality of discretization signals based on a detection result thereof.
