Polar codes are a recently proposed family of provably capacity-achievingerror-correction codes that received a lot of attention. While theirtheoretical properties render them interesting, their practicality compared toother types of codes has not been thoroughly studied. Towards this end, in thispaper, we perform a comparison of polar decoders against LDPC and Turbodecoders that are used in existing communications standards. More specifically,we compare both the error-correction performance and the hardware efficiency ofthe corresponding hardware implementations. This comparison enables us toidentify applications where polar codes are superior to existingerror-correction coding solutions as well as to determine the most promisingresearch direction in terms of the hardware implementation of polar decoders.
