Optimal LLR Clipping Levels for Mixed Hard/Soft Output Detection
Abstract—Consider a communications system where the detector generates a mix of hard and soft outputs, which are then fed into a soft-input channel decoder. In such a setting, it...

Detecting common elements of types
: We describe an algorithm approximatingthe following question: Given two types t1 and t2, are there instances (t1) and (t2) denoting a common element? By answering this question w...
