Abstract
A data communications receiver incorporating soft decision error correction decoding and a means to set the amplitude or threshold for quantized soft decisions in a near-optimum manner to a soft decision decoder. In one embodiment the means for setting the amplitude or threshold measures the soft decisions from a quantizer and marks data bits as weak or strong. The gain or threshold is automatically adjusted to achieve a desired fraction if each marking. The desired fraction is chosen as the value that optimizes performance of the soft decision decoder.
