The coalesced access to the message of variable node. Therein, \(CW_{0} ...CW_{K}\) represent different codewords, \(K + 1\) is the number of codewords decoded at the same time, \(N_{0} ...N_{e}\) represent \(e + 1\) check nodes, \(L_{{v_{i} }}^{k}\) is the message of the i-th variable node in the k-th codeword, \(0 \le i \le g\), \(g + 1\) is the total number of variable nodes, and \(th_{k}\) is the k-th thread, \(0 \le k \le K\).
