Abstract:
1. A method for encoding N bits of information for a packet data service in a mobile communication system supporting the packet data service, wherein N is a positive integer, the method comprising the steps of: encoding the N bits of information by using a [32, N] second order Reed Muller code, if a [40, N] encoding is used; encoding M bits of information requiring an enhanced error correcting capability from among the N bits of information by using a [8, M] unequal protection code, wherein M is a positive integer smaller than N; and concatenating symbols encoded by the [32, N] second order Reed Muller code with symbols encoded by the [8, M] unequal protection code, thereby outputting a [40, N] codeword comprising 40 encoded symbols, wherein the [32, N] second order Reed Muller code comprises an N number of [32, N] basis sequences from among seven basis sequences each having a length of 32, denoted by:
