Abstract
There is described a multi-mode unrolled decoder. The decoder comprises a master code input configured to receive a polar encoded master code of length N carrying k information bits and N−k frozen bits, decoding resources comprising processing elements and memory elements connected in an unrolled architecture and defining an operation path between the master code input and an output, for decoding a polar encoded code word, at least one constituent code input configured to receive a polar encoded constituent code of length N/p carrying j information bits and N/p−j frozen bits, where p is a power of 2, and at least one input multiplexer provided in the operation path to selectively transmit N/p bits of one of the master code and the constituent code to a subset of the decoding resources.
