US Patent 11290129 Polar encoder, communication unit, integrated circuit and method therefor

A polar encoder kernel, a communication unit, an integrated circuit and a method of polar encoding are described. The polar encoder kernal is configured to receive one or more bits from a kernal information block having a kernal block size of N; and output one or more bits from a kernal encoded block having a block size that matches the kernal block size N; wherein the polar encoder kernal comprises a decomposition of a polar code graph having multiple columns that are processed by a reused single datapath, at least one of said multiple columns contains two or more stages and where each column of the multiple columns is further decomposed into one or more polar code sub-graphs and is configured to process encoded bits one polar code sub-graph at a time.
