This paper investigates the performance of a Low-Density Parity Check codes (LDPC)-coded system transmitted over A WGN channels using octal partial response Continuous Phase Modulation (CPM). The system provides an attractive option for spectral efficient communications systems. The CPM modulator can be decomposed into a ring continuous-phase encoder (CPE) followed by a memoryless modulator (MM), where the CPE is as the same algebra as convolutional code. With a pragmatic approach, The LDPC codes are designed through the use of the proposed analysis technique based on extrinsic information transfer (EXIT) charts. We propose a belief propagation (BP)-based iterative decoding algorithm at the ..
