Problems solved by technology

However, there is a problem in that if there is a large amount of error, saturation occurs so that error correction cannot be performed in any direction in two dimensions, thereby losing the ability to repeat error correction, which is the best characteristic of two-dimensional error correction

Embodiment Construction

[0018] Embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0019] figure 1 A schematic diagram illustrating a code structure of an error correction coding method using a three-dimensional (3D) Reed-Solomon code according to a first embodiment of the present invention. Such as figure 1 As shown, several pieces of input information are arranged in a 3D data block 10, and the 3D data block 10 is realized by an information symbol array (k1, k2, k3), wherein k1, k2 and k3 are positive integers. In other words, the 3D data block 10 has a (k1, k2, k3) array structure, where k1*k2*k3 information symbols are arranged along the horizontal, vertical and z-axis directions.

[0020] 3D error correction encoding is performed with respect to the 3D data block 10 so that horizontal, vertical, and z-axis error correction parity symbols are added to the 3D data block 10 in the horizontal, vertical, and z-axis directions, respec...

Abstract

The invention relates to an error correction coding method using a three-dimensional Reed-Solomon code. In this error correction coding method, several pieces of input information are arranged in three-dimensional data blocks. Three-dimensional error correction coding is performed on the three-dimensional data block, so that horizontal, vertical and z-axis error correction parity symbols are respectively added to the three-dimensional data block in the horizontal, vertical and z-axis directions.

Description

technical field [0001] The present invention relates to a three-dimensional error correction coding method; in particular, to a three-dimensional error correction coding method, which uses a one-Odd-even parity check in digital information equipment or communication equipment to perform error correction coding on three-dimensional data blocks, thereby improving correction wrong performance. Background technique [0002] One parameter used to determine the quality of digital communication systems is the "Bit Error Rate (BER)". The BER is a parameter for determining the probability of occurrence of erroneous bits in the output of the receiving system. Storage devices such as tapes, disks, compact discs (CDs), digital versatile discs (DVDs) and barcodes, mobile communications devices such as cellular phones and microwave links, satellite communications devices and digital television typically require a BER of 10 -9 or lower. [0003] To increase the BER without increasing th...
