Abstract:
1. An apparatus for constant amplitude encoding of a transmission signal, the apparatus comprising: an encoding module sequentially performing horizontal encoding and vertical encoding on an input signal, wherein the encoding module includes: a horizontal encoding unit performing horizontal encoding on the input signal by using a certain [n,k] code; and a vertical encoding unit receiving the signal which has been encoded by the horizontal encoding unit and performing vertical encoding on the received signal by using a [4,m] odd parity code, n being the number of bits to be encoded in a horizontal direction, k being the number of bits of information to be encoded, and m being a value for determining the horizontal encoding; and a spreading and multiplexing module for spreading the signal which has been encoded by the encoding module and multiplexing the spread signal in a vertical direction to output a data stream having a constant amplitude, wherein the encoding module and the spreading and multiplexing module are incorporated in one or more processors.
