ABSTRACT:
A plurality of generator polynomials are prepared for error correction and stored in a table by assigning a specific table number to each generator polynomial. Each generator polynomial provides a different error correction capability so that a different number of error correction bits are added to each set of transmission data. For radio communication, an electric field intensity is first measured, and in accordance with this electric field intensity, a generator polynomial to be used at that time for error correction calculation is determined. It is therefore possible to change the number of error correction bits in accordance with the environment at that time and to perform efficient error correction. For example, if a base station is in a near area, an error rate is small so that the number of addition bits is reduced.
