Abstract
Embodiments described herein provide a code generation mechanism (FIG. 3, 301) in a Polar encoder (FIG. 2, 204) to determine a bit type (FIG. 3, 312) corresponding to each coded bit in the Polar code before sending the data bits for encoding (FIG. 3, 303). For example, each bit in the Polar code is determined to have a bit type of a frozen bit, parity bit, an information bit, or a cyclic redundancy check (CRC) bit based at least on the respective reliability index of the bit from a pre-computed reliability index lookup table (FIG. 4A, 411). In this way, the bit type determination can be completed in one loop by iterating the list of entries in the pre-computed reliability index lookup table.
