Abstract
In this paper the impact of roundoff mechanisms on the performance of message-passing LDPC decoding is studied. It is shown that finite word length introduces error by means of two mechanisms, each of which is analyzed. The impact and behavior of the two mechanisms are clarified by experimental results.
