1. A signal transmission device, comprising:
- a plurality of reception processors configured to;
handle respective channels of a plurality of channels;
handle multichannel transmission based on a division of frequency bands to be used for a communication,wherein the communication occurs on separate frequencies for transmission and for reception,wherein a total number of the plurality of channels is equal to or greater than three,wherein, based on a full-duplex two-way communication that is applied in any combination of two channels of the plurality of channels, one of the plurality of reception processors includes a first trap circuit configured to suppress a signal component of at least a low frequency side or a high frequency side of a first channel, wherein at least the low frequency side or the high frequency side to be suppressed has a lesser attenuation degree in a gain frequency characteristic with respect to a self channel of the one of the plurality of reception processors, andwherein the one of the plurality of reception processors includes an amplifier, wherein the amplifier is configured to have frequency selectivity for the self channel and amplify a received signal.

Abstract
There is provided a signal transmission device including reception processing units for respective channels, so as to enable multichannel transmission by dividing frequency bands. The total number of channels is equal to or greater than three. When full-duplex two-way communication is applied in any combination of two channels, one of reception processing unit include a signal suppressing unit configured to suppress a signal component of a channel other than a self channel.
