Patent ID: 7333546

Claim:
A coding method in a mobile communication system, for receiving 5 information bits and generating a coded symbol stream comprised of 20 coded symbols, the coding method comprising the steps of: generating 5 coded symbol streams having a length 32 by encoding each of the 5 information bits with a different Walsh code each having a length 32, and generating a coded symbol stream comprised of 32 coded symbols by XORing the 5 coded symbol streams in a symbol unit; and generating a coded symbol stream comprised of 20 coded symbols by puncturing 2 nd , 4 th , 5 th , 6 th , 8 th , 9 th , 10 th , 11 th , 12 th , 13 th , 14 th , and 30 th coded symbols among the 32 coded symbols.
