Construction of short-length LDPC codes with good, both waterfall and error-floor, behavior is still an attractive research problem. Recently proposed construction algorithms in this field are based on remarkably simple ideas, but yet, their effectiveness can still be questioned. In this paper we investigate a novel measure of goodness of a given LDPC code, namely its ACE spectrum, based on a previously introduced ACE metrics associated with each cycle in LDPC code graph.
