ABSTRACT:
With attention focused on the most significant bit (sign indicating positive or negative) of a soft decision value, the present invention provides a method of deciding whether iterations of soft decision decoding of turbo decoding should be terminated or not. A change of a positive
egative bit value included in a soft decision result for each bit of a received codeword is monitored. When the values of the positive
egative bits cease to fluctuate and such a tendency is observed for almost all bits of the received codeword, it is decided that the positive
egative bits have converged. Termination of iterations of soft decision decoding is determined based on the decision result.
