Analysis of Polarization-adjusted Convolutional Codes (PAC): A Source-Channel Coding Method

Polarization-adjusted convolutional (PAC) code improves the error-correction ability of polar codes by concatenating a convolutional transform with polar transform. In this paper, we establish a source-channel coding framework to develop the theory of the optimal rate assignment for PAC codes. In the source-channel coding model, each column of the convolutional matrix corresponds to a source encod...
