Abstract
An apparatus for determining a bit index for a parity bit of a polar codeword is disclosed. Each index of a polar codeword may have an associated weight and an associated reliability value. The apparatus may compare the weights and reliability values of a group of bit indices in parallel to determine a bit index of the group associated with the lowest weight and highest reliability value. Additional groups may be processed until all of the bit indices of the polar codeword have been examined and the bit index with the lowest weight and highest reliability value is identified.
