The present disclosure is directed to communication systems and more specifically to communication devices having encoder and/or decoder blocks employing Low Density Parity Check Convolutional Codes (LDPC CCs). According to exemplary embodiments, improved LDPC CC techniques are disclosed to construct the syndrome former of an LDPC-CC code in a systematic way based on desired Rate (b/c), Memory (ms) and Period (T) while achieving specific Degree Distribution (dv and dc), Girth, and ACE constraints (nACE, dACE) for a desired configuration.
