    Abstract: PURPOSE: A method and an apparatus for transmitting/receiving data by using a satellite channel are provided to use low cost analog device in a terminal by providing excellent transmission performance under a weak communication environment. CONSTITUTION: When receiving bit data, the encoding unit performs channel encoding through an e-BCH(extend BCH) code. An interleaver(103) interleaves the encoded data through the encoding unit. A modulation unit(105) modulates interleaved data through a CPM(Continuous Phase Modulation) method which use 4 symbols, and a transmission unit(107) transmits the modulated data to a primary center.
