Abstract

A method for encoding information bits using a zipper code. The zipper is associated with a real buffer for receiving the information bits, a first virtual buffer, a second virtual buffer, and two mapping functions φand φ. Each row of the real buffer, a corresponding row of the first virtual buffer, and a corresponding row of the second virtual buffer form a codeword of a component code. The two mapping functions φand φare for mapping each group of c bits in each row of the real buffer to c bits in one or more subsequent rows of the first virtual buffer and to c bits in one or more subsequent row of the second virtual buffer, respectively. The c bits in the first virtual buffer are in different rows thereof, and/or the c bits in the second virtual buffer are in different rows thereof.
