PA (Product Accumulate) codes achieve perfomance near the Shannon limit for BPSK, have low encoding and decoding complexity, and have flexible rate adaptivity for all rates above 1/2. In this paper, we propose a new method of application of PA codes to multilevel modulation with multilevel coding and BICM-ID(Bit Interleaved Coded Modulation with Iterative Decoding). First, to adjust code rate flexibly, we investigate perfomances of PA codes and GPA (Generalized Product Accumulate) codes that have two different single parity check codes as component codes, and we show a procedure to design PA codes or GPA codes with different component codes for wide range of code rate. Next, we identify labeling methods that give the lowest decoding error probability for BICM-ID and multilevel coding. Computer simulation demonstrates that multilevel coding systems and BICM-ID systems with PA codes or GPA codes designed with our procedure give performances near the Shannon limit. |
