Sliced polar codes
A variation on channel polarization coding is presented. In standard channel polarization coding the code length is an integral power of two. Our scheme allows modifying the code at the graph definition level to an arbitrary blocklength. Working at the graph definition level of the code enables the utilization of the newly produced codes for every decoding scheme that utilize the graph definition of the code with a substantial saving in operations and storage resources of the decoder at hand. This saving is of major potential for solid state storage where information length of interest is commonly integral power of two and high coding rate is usually considered. About 45% hardware resources are estimated to be saved in various decoder architectures at hand.
