Planar Quantum Low-Density Parity-Check Codes with Open Boundaries

open access: yesPRX Quantum
Although high-threshold and low-overhead quantum low-density parity-check (qLDPC) codes, such as bivariate bicycle (BB) codes, can reduce the physical-qubit cost by an order of magnitude compared to the Kitaev toric code, their torus layout remains ...

Systematic Luby Transform Codes and their Soft Decoding [PDF]

open access: yes, 2007
Luby Transform codes (LT) were originally designed for the Binary Erasure Channel (BEC) encountered owing to randomly dropped packets in the statistical multiplexing aided classic wireline-based Internet, where transmitted packets are not affected by the

Reordered static layered schedule for 5G low‐density parity‐check codes

open access: yesElectronics Letters
The error performance of the 5G low‐density parity‐check codes is significantly impacted by the update order of layers. At present, the row degree (RD) and the number of punctured bits (PBs) are widely used to decide the update order of layers. Here, the

Burst-by-burst Adaptive Joint-Detection CDMA/H.26L Based Wireless Video Telephony using TTCM and LDPC Codes [PDF]

open access: yes, 2003
A low bit-rate video coding techniques using the H.26L standard codec for robust transmission in mobile multimedia environments are presented. For the sake of achieving error resilience, the source codec has to make provisions for error detection ...

CONSTRUCTION OF REGULAR LDPC LIKE CODES BASED ON FULL RANK CODES AND THEIR ITERATIVE DECODING USING A PARITY CHECK TREE [PDF]

open access: yesICTACT Journal on Communication Technology, 2011
Low density parity check (LDPC) codes are capacity-approaching codes, which means that practical constructions exist that allow the noise threshold to be set very close to the theoretical Shannon limit for a memory less channel.

A construction of the high-rate regular quasi-cyclic LDPC codes

open access: yesEURASIP Journal on Wireless Communications and Networking, 2019
In this paper, a scheme to construct the high-rate regular quasi-cyclic low-density parity-check (QC-LDPC) codes is developed based on the finite geometry low-density parity-check (LDPC) codes.

Flexible On-line Construction of IRA Codes for Packet Erasure Correction with Application to Aeronautical Communications [PDF]

open access: yes, 2011
In many applications erasure correcting codes are used to recover packet losses at high protocol stack layers. The objects (e.g. files) to be transmitted often have variable sizes, resulting in a variable number of packet to be encoded by the packet ...
