Abstract: Digital data signals such as, e.g., turbo-encoded data signals subject to decoding, are processed by producing a plurality of families of metrics for these signals while allowing one or more of these metrics to wrap through a respective independent wrapping operation. A decoder, e.g., a decoder for turbo-encoded digital signals computes differences of metrics selected out of the plurality of families of metrics by excluding differences of metrics derived through independent wrapping operations (e.g., wrapping metrics from different families) and generates signals representative of order relationships of combinations of corresponding unwrapped metrics as a function of said differences.

Abstract translation: 诸如例如经解码的turbo编码数据信号的数字数据信号通过产生用于这些信号的多个度量系列来处理，同时允许这些度量中的一个或多个包围相应的独立包装操作。 解码器，例如用于turbo编码的数字信号的解码器，通过排除通过独立包装操作（例如，来自不同家族的包装度量）导出的度量的差异来计算从多个度量系列中选出的度量的差异，并产生代表 作为所述差异的函数的相应展开度量的组合的顺序关系。
