Abstract
Carrier phase often suddenly change while receiver PLL unlock at PSK modulation communication system, it lead to likelihood information sequence which input of LDPC decoder not accurate and decode fail. This paper analyzed the regularity of LLR information after Cycle-Slip happened and combine with MS decode algorithm improved the Anti-Cycle-Slip decode algorithm. It not only raised the ability of Anti-Cycle-Slip, but also alters the conclusion that all check-nodes degree must be odd number, this found provide a more convenient way for LDPC Anti-Cycle-Slip design
