Efficient code descriptions of rate compatible polar codes are studied. An efficient code description method, so-called the polarization weight sequence that defines multiple codewords, was proposed in 3GPP standardization. We verify the validity of the method for various environments. We assess the performance degradation under successive cancellation (SC) decoding and SC list decoding compared with...
A parameter optimization scheme of block interleaver for polar coding with bit-interleaved coded modulation (BICM) is proposed in this paper. We analyze the characteristics of a random interleaver applied to polar codes with high-order modulation, which is ideal but infeasible to implement. Then we derive the parameter optimization algorithm of block interleaver for polar coding with BICM. The block...
This paper proposes a new architecture Deep Convolutional and Recurrent writer (DCRW) for image generation by adapting the deep Recurrent attentive writer (DRAW) architecture which is a sequential variational auto-encoder with a sequential attention mechanism for image generation. The main difference between DRAW and DCRW is that in DCRW we have replaced RNN in encoder with CNN and after replacement...
In this letter, a new secure information transmission scheme based on polar codes with a pre-shared secret key is proposed. In polar codes, after the channel polarization is induced, good split channels are used to transmit the user message and bad channels are utilized to support the reconstruction of the message by sharing fixed information. If the fixed information in bad channels is secret, an...
The application of polar coding to rate-adaptive asymmetric Slepian-Wolf coding is considered. The encoder transmits the syndrome set which includes high entropy bits to the decoder to achieve the optimal compression. It means that the encoder must know the correlation between two sources and the syndrome set varies according to this correlation. In this paper, we propose polar source coding scheme...
