Patent ID: 7733837

Claim:
A method for adjusting the number of input bits to a decoder by a range adjuster in a Code Division Multiple Access (CDMA) mobile communication system, the method comprising the steps of: (a) dividing a range that can be expressed with the number of input bits inputted to the range adjuster into three or more sections; (b) counting output values of the respective sections outputted from the range adjuster for a predetermined time; (c) comparing a count output value of a specific section with other count output values of the other sections; and (d) adjusting the number of input bits to the decoder so that a distribution of the count output values of the sections have a predetermined distribution form, wherein the sections to be expressed are adjusted according to the number of input bit values mapped to one output bit value and the number of input bit values mapped to the one output bit value is proportional to the range of the sections to be expressed.
