Abstract: Methods, systems, and devices are described for wireless communications at a wireless device. A wireless device may adaptively select a parity check matrix to increase the reliability of signal transmission by adapting to different channel statistics and channel types (e.g., erasure channels, channels with additive white Gaussian noise, and channels with discrete or continuous alphabets). For example, polarization codes (i.e., codes based on rows of a polarization matrix) may be used to construct parity check matrices on-the-fly given an estimation of dynamic channel conditions or diverse channel structures. The channel may be decomposed into polarized sub-channels corresponding to the polarization codes, and mutual information profiles may be determined for each of the polarized sub-channels. The parity check matrix corresponding to the polarization codes may be constructed based on the mutual information profile of all polarized sub-channels. The wireless device may encode or decode data based on the constructed parity check matrix.

Abstract translation: 描述了无线设备上的无线通信的方法，系统和设备。 无线设备可以自适应地选择奇偶校验矩阵，以通过适应不同的信道统计和信道类型（例如，擦除信道，具有加性白高斯噪声的信道和具有离散或连续字母的信道）来提高信号传输的可靠性。 例如，鉴于动态信道条件或不同信道结构的估计，偏振码（即，基于偏振矩阵的行的代码）可用于构建奇偶校验矩阵。 信道可以被分解成对应于偏振码的极化子信道，并且可以为每个偏振子信道确定互信息曲线。 可以基于所有极化子信道的互信息轮廓来构造对应于偏振码的奇偶校验矩阵。 无线设备可以基于构造的奇偶校验矩阵对数据进行编码或解码。
