Claim:
1. A wireless communication apparatus including a plurality of input ports and a plurality of output ports, the wireless communication apparatus inputting, for each input port, an analog signal with a plurality of signals multiplexed thereon by a frequency division multiplexing method, the wireless communication apparatus comprising: an Analog-to-Digital (A/D) converter circuit that is provided for each input port and converts the analog signal that has been input to a digital signal; a demultiplexer circuit that is provided for each input port, inputs the digital signal obtained by conversion by the A/D converter circuit, and separates the digital signal that has been input into the plurality of signals; a prestage rearrangement circuit that is provided for each input port, inputs the plurality of signals from the demultiplexer circuit, and rearranges channels of the plurality of signals that have been input to be output as a plurality of prestage rearranged signals; a switch circuit including a per-channel processing circuit having a configuration in which a block that performs a switching process may be separated for each at least one channel, the per-channel processing circuit inputting at least one of the plurality of prestage rearranged signals output from the prestage rearrangement circuit corresponding to a channel of the per-channel processing circuit as a signal before switching, applying the switching process to the signal before the switching that has been input, and outputting the signal before the switching with the switching process applied thereto as a switched signal, the switch circuit outputting switched signals output from the per-channel processing circuits as a plurality of switched signals for each output port; a poststage rearrangement circuit that is provided for each output port, inputs the plurality of switched signals output from the switch circuit for each output port, and rearranges channels of the plurality of switched signals that have been input to be output as a plurality of poststage rearranged signals; a multiplexer circuit that is provided for each output port, inputs the plurality of poststage rearranged signals output from the poststage rearrangement circuit, and multiplexes the plurality of poststage rearranged signals that have been input, by the frequency division multiplexing method; and a Digital-to-Analog (D/A) converter circuit that is provided for each output port and converts the digital signal obtained by multiplexing by the multiplexer circuit to an analog signal.
