Abstract: Decoding error correcting codes transmitted through multiple wire twisted pair cables with uneven noise on the wires. A novel approach is presented by which the metrics may be calculated for signals received over multi-wire (or alternatively referred to as multi-channel, and/or multi-path) communication channels to exploit an uneven distribution of noise among those wires for improved performance. In addition, this approach may also be performed in combination with employing an amplification factor to modify the metrics employed when performing ECC (Error Correcting Code) decoding. Moreover, when information is known concerning which 1 or more paths (e.g., wires) has an SNR that is different (e.g., lower in some cases) from the others, an even better adapted means of calculating the metrics associated with each of the paths (e.g., wires) may be employed to provide for improved performance with respect to iterative decoding processing of signals encoded using ECCs.

Abstract: A short length LDPC (Low Density Parity Check) code and modulation adapted for high speed Ethernet applications. In some instances, the short length-LDPC code and modulation may be employed within the recommended practices currently being developed by the IEEE 802.3an (10GBASE-T) Task Force. The IEEE 802.3an (10GBASE-T) Task Force has been commissioned to develop and standardize communications protocol adapted particularly for Ethernet operation over 4 wire twisted pair cables. A new LDPC code, some possible embodiments of constellations and the corresponding mappings, as well as possible embodiments of various parity check matrices, H, of the LDPC code are presented herein to provide for better overall performance than other proposed LDPC codes existent in the art of high speed Ethernet applications. Moreover, this proposed LDPC code may be decoded using a communication device having much less complexity than required to decode other proposed LDPC codes existent in this technology space.
