Abstract
A polar code decoder includes: processing elements each receiving a pair of input values and applying a first or a second predetermined mathematical function depending on a provided function control signal; a first memory that stores at least one of the outputs from processing elements and a plurality of channel values relating to a received polar code to be decoded; a second memory that stores indices of a plurality of frozen bits each representing a bit within an information-bit vector of the polar code being decoded; and a computation block that receives a plurality of inputs from a portion of the processing elements and generates an output that is can be set to a predetermined frozen value or to a calculated value, depending on whether a current index of the bit being decoded is indicated as frozen or not frozen.
