Abstract: The embodiments of the present disclosure disclose a soft bit un-uniform quantization method, apparatus, computer program and storage medium. The soft bit un-uniform quantization method comprises: determining a threshold value; obtaining a quantization step according to the threshold value; obtaining a first data after a QAM demodulating and before a Turbo decoding in a wireless communication system; and performing a soft bit un-uniform quantization on the first data to obtain a quantization result according to the threshold value and the step. According to the present disclosure, the data after the QAM demodulating and before the Turbo decoding may obtain a distinguished Euclidean distance value and thus the performance can be improved greatly.
