Polar codes under cyclic redundancy check-aided successive cancellation list (CA-SCL) decoding can outperform the turbo codes and the LDPC codes at the cost of high complexity and decoding delay. In order to reduce the decoding complexity, in this paper we propose a hybrid parity-check and CRC aided SCL decoding scheme for polar codes. Simulation results under the binary input additive white Gaussian...
An encryption method based on Turbo codes is proposed in this paper. In the scheme, two measures are adopted to encrypt information: Firstly, binary pseudo random sequence generated by Logistic chaotic mapping is used to encrypt the first output of Turbo codes, at the same time to control the generated matrix of the second and third output; Secondly, the output of interleaver is controlled by the...
In this paper, a scheme of modulation diversity with multiple turbo codes is studies. Rotation of the signal constellation together with in-phase and quadrature channel interleaving is known to prove good performance gains over fading channels for multi level modulation methods. Recently it has been shown that multiple turbo codes with very simple sub-codes outperform conventional 2-parallel turbo...
