Polar codes are applied to bit-interleaved coded modulation system with iterative decoding (BIPCM-ID) system. To optimize the iterative decoding performance, conventional polar coding construction is modified by extrinsic information transfer (EXIT) chart methodology. Simulation results show that BIPCM-ID system based on the proposed technique can outperforms BIPCM over 16-ary quadrature-amplitude...
A parallel concatenated coding structure, which can improve the performance of polar codes in finite-length regime, is proposed. In the proposed structure, the encoder is built using two systematic polar codes (SPCs), and the decoder adopts iterative belief propagation decoding algorithm. Numerical results in the binary-input additive white Gaussian noise channel indicate that the proposed coding...
