In this thesis, ldpc codes of shorter length are considered as they offer advantages in terms of latency and complexity, at the cost of performance degradation from the increased number of short cycles in the graph.

ldpc thesis Compared to randomly generated ldpc codes, structured ldpc codes—such as the ldpc code used in the dvb-s2 standard—can have simpler and therefore lower-cost hardware—in particular, codes constructed such that the h matrix is a circulant matrix.
