Problems solved by technology

[0011] However, the types of LDPC codes proposed using this prior art are narrow, and there is little flexibility in designing other types of LDPC codes using this approach
The lack of flexibility is a significant challenge for designing such LDPC codes and / or communication devices implemented using such LDPC codes

Embodiment Construction

[0167] The goal of a digital communication system is to transmit digital data from one location or subsystem to another without error or with an acceptably low error rate. As shown in Figure 1, data can be transmitted over a variety of channels in a variety of communication systems: magnetic media, wireless networks, fiber optics, copper wires, and other media.

[0168] 1 and 2 are schematic diagrams of communication systems 100 and 200 established according to the present invention, respectively. Referring to FIG. 1 , a communication system 100 includes a channel 199 that connects a communication device 110 (comprising a transmitter 112 with an encoder 114 and a receiver 116 with a decoder 118 ) at one end of the communication channel 199 to a communication device at the other end of the communication channel 199 . A device 120 (comprising a transmitter 126 with an encoder 128 and a receiver 122 with a decoder 124) is connected. In some embodiments, both communication device...

Abstract

Construction of LDPC (Low Density Parity Check) codes using GRS (Generalized Reed-Solomon) code. A novel approach is presented by which a GRS code may be employed to generate a wide variety of types of LDPC codes. Such GRS based LDPC codes may be employed within various types of transceiver devices implemented within communication systems. This approach may be employed to generate GRS based LDPC codes particular designed for various application arenas. As one example, such a GRS based LDPC code may be specifically designed for use in communication systems that operate in accordance with any standards and / or recommended practices of the IEEE P802.3an (10GBASE-T) Task Force.

Description

technical field [0001] The present invention relates to communication systems, and more particularly, the present invention relates to the generation of codes that can be used in communication systems to generate coded signals. Background technique [0002] Data communication systems have been continuously developed for many years. In recent years, communication systems using repetitive error-correcting codes are the focus of researchers. One of the most concerned is a communication system using a low density parity check (Low Density Parity Check, LDPC for short) code. In the case of the same signal-to-noise ratio, the error rate of the communication system with repetitive coding is usually lower than that of selective coding. [0003] A continuing and major direction of development in this field is the reduction of the signal-to-noise ratio necessary in communication systems to achieve a specific bit error rate. The ideal goal is to try to study the Shannon's limit in co...
