Abstract
Disclosed are systems and methods for transmission and reception of data bits. A plurality of data bits are received. FEC-based encoded data bits are generated in accordance with a zipper code framework incorporating component non-binary codes. The zipper code framework includes a buffer having a virtual buffer and a real buffer. Codewords associated with the FEC-based encoded data bits are stored in rows of the real buffer. A given codeword in a given row of the real buffer is mapped to different rows of the virtual buffer in a quasi-diagonal interleaving manner.

A transmitter comprising:
- a forward error correction (FEC)-based encoder configured to:
- receive a plurality of data bits;
- generate FEC-based encoded data bits in accordance with a zipper code framework incorporating component non-binary codes, wherein:
- the zipper code framework includes a buffer having a virtual buffer and a real buffer, and
- the FEC-based encoder stores codewords associated with the FEC-based encoded data bits in rows of the real buffer;
- and
- map a given codeword in a given row of the real buffer to different rows of the virtual buffer in a quasi-diagonal interleaving manner, the mapping comprising:
- selecting at least a first group of bits from the given codeword stored in the given row of the real buffer and copying the first group of bits in a first row of the virtual buffer such that the first row of the virtual buffer is diagonally adjacent to the given row of the real buffer, and
- selecting at least a second group of bits from the given codeword stored in the given row of the real buffer and copying the second group of bits in a second row of the virtual buffer adjacent to the first row such that the second group of bits is diagonal to the first group of bits.

A receiver comprising:
- a receiver processor configured to:
- receive an analog signal transmitted by a transmitter, and
- process the received analog signal and generate received forward error correction (FEC)-based encoded bits in accordance with a zipper code framework that incorporates component non-binary codes;
- and
- a FEC-based decoder configured to decode the received FEC-based encoded bits in accordance with a non-binary decoding technique, store codewords associated with the received FEC-based encoded bits in rows of a real buffer associated with the zipper code framework, and generate information bits.
