ABSTRACT:
A communication apparatus, a signal component demultiplexing apparatus, and a filter apparatus to reduce a load of FFT processing in a receiver in multi-carrier communication. The receiving apparatus provides a signal component demultiplexing apparatus before an FFT circuit and extracts only the required symbol series. The signal component demultiplexing apparatus has hierarchically arranged branching circuits each including a symbol delay circuit, a phase offset adjustment circuit, an adder circuit, and a subtractor circuit, one symbol string being output from the adder circuit and another symbol string being output from the subtractor circuit.
