Abstract—To increase throughput efficiency, LDPC (Low Density Parity Codes) codes with various high coding rates are employed in DVB-S3 system. However, the more the coding rate increases, the more performance decreases sharply. This paper proposed a new P-FTN (Punctured-FTN) method which combine a punctured LDPC with FTN (Faster Than Nyquist) method to increase performance while maintain throughput as compared to high coding rates of LDPC codes. Furthermore, this paper present efficient receiver structure suitable for P-FTN with LDPC decoder. As a result of computer simulation, P-FTN method has better performance than the high coding rate LDPC method.

Index Terms—LDPC, high coding rate LDPC, FTN, punctured, P-FTN.
