Symmetry-based subproduct codes

Abstract: Recently, a new type of product-like codes, known as half-product codes, have been studied for OTN applications. Motivated by these codes, new classes of symmetry-invariant subproduct codes are proposed and investigated under iterative hard-decision decoding. A subset of the new class of quarter product codes has lower error floors than comparable half-product codes in terms of length, rate and performance.
