ABSTRACT:
A communication apparatus includes a transmitter and a receiver, wherein the transmitter further includes: an interleaver that rearranges positions of bits of an information frame; an FEC encoder that performs an error correction encoding to the information frame whose bit positions have been rearranged; and a selector that inserts FEC parity into predetermined positions of the information frame, to thereby generate a transmission signal, whereas the receiver includes: a selector that extracts an information frame part and an FEC parity part from a reception signal; an interleaver that rearranges positions of the bits of the information frame part using the same rule as that used at that transmitter side; an FEC decoder that corrects an error of bits rearranged based on the error correction parity part; and a de-interleaver that reproduces an information frame by returning positions of error-corrected bits to original bit positions.
