| Abstract: | In this paper a method using quadratic congruential sequences to design regular LDPC code is proposed. The main advantage of this method is that the structure of the encoder is deterministic, rather than having to store the encoder structure graph in memory. Simulation results show that these codes provide almost the same performance of a constrained pseudorandom construction that explicitly avoids cycles of length less than or equal to four. |
