Abstract:
1. A method for allocating bits to sub-channels for data transmission in a wireless communication system, the method comprising the steps of: (a) setting a number of bits allocated to all sub-channels to an initial value; (b) calculating a number of sub-channels required for bit allocation; (c) determining an encoding detection sequence for each subcarrier in a state in which the initial value is set; (d) calculating a weight vector for all subcarriers according to the encoding detection sequence; (e) determining a sub-channel with a least 2-Norm value from among all sub-channels by using the calculated weight vector; (f) selecting the sub-channel with the least 2-Norm value for bit allocation; and (g) allocating K bits to the selected sub-channel, wherein steps (e), (f) and (g) are repeated until a number of selected sub-channels for the bit allocation satisfies D where D
