An encoding method in a mobile communication system, for receiving 4 input information bits,
encoding the 4 input information bits with different, walsh codes of length 16, and outputting a coded
symbol stream having 24 coded symbols using a coded symbol stream having 16 coded symbols
obtained by XORing the encoded input information bits by an XOR operator. The encoding method
comprises repeating the coded symbol stream having 16 coded symbols once, and thus outputting a
coded symbol stream having 32 coded symbols; and puncturing 0 th , 1 st , 2 nd , 3 rd , 4 th , 5 th , 6 th and 16 th
symbols from the 32 coded symbols, and thus outputting the coded symbol stream having 24 coded
symbols.
