Layer decoding of LDPC codes for DVB-S2

Abstract (in Japanese) (See Japanese page) 
(in English) In the most common form of message-passing decoding, the LDPC decoder are performed by so-called two-phase message-passing algorithm(TPMP). For TPMP, the messages are updated iteratively at two different phases, first check node and then variable node.
In this paper, the layer decoding algorithm is applied for DVB-S2 to reduce the iteration number compared to TPMP. This paper shows in detail how to exploit the partly parallel layer schedule for DVB-S2. Simulation results show that the layer decoding performs well based on the proposed layer schedule, which sustains the partly parallel structure and fasts the convergence speed almost 2 times than TPMP.
