A rate R=5/20 hypergraph-based woven convolutional code with free distance 120 Abstract-A rate R = 5/20 hypergraph-based woven convolutional code with overall constraint length 67 and constituent convolutional codes is presented. It is based on a 3-partite, 3uniform, 4-regular hypergraph and contains rate R c = 3/4 constituent convolutional codes with overall constraint length 5. Although the code construction is based on low-complexity codes, the free distance of this construction, computed
