Optical OFDM Error Floor Estimation by Means of OTDR Enhanced by Front-End Optical Preamplifier [PDF]
Optical time-domain reflectometer (OTDR) enables simple identification and localization of a plethora of refractive and reflective events on a fiber link, including splices, connectors and breaks, and measuring insertion/return loss.

LDPC Error Floor Improvement [PDF]
The error-correcting performance of low-density parity check (LDPC) codes, when decoded using practical iterative decoding algorithms, is known to be close to Shannon limits.

Bit Error Floor Reduction for MQAM Signals in the Presence of Phase Error
We propose a method to form a non-uniform decision boundary (NUDB) for $M$ -ary quadrature amplitude modulation (MQAM) signals to reduce bit error floor (BEF) in the presence of phase error.

Controlling the Error Floor in LDPC Decoding [PDF]
The error floor of LDPC is revisited as an effect of dynamic message behavior in the so-called absorption sets of the code. It is shown that if the signal growth in the absorption sets is properly balanced by the growth of set-external messages, the error floor can be lowered to essentially arbitrarily low levels.

Distributed LT Codes With Improved Error Floor Performance [PDF]
Distributed Luby transform (DLT) codes achieve a significant performance improvement in multi-source relay networks compared with the individual Luby transform (LT) code designed for each source.

Error Floor Analysis of LDPC Column Layered Decoders [PDF]
In this paper, we analyze the error floor of column layered decoders, also known as shuffled decoders, for low-density parity-check (LDPC) codes under saturating sum-product algorithm (SPA). To estimate the error floor, we evaluate the failure rate of different trapping sets (TSs) that contribute to the frame error rate in the error floor region.

Improved decoding and error floor analysis of staircase codes [PDF]
Staircase codes play an important role as error-correcting codes in optical communications. In this paper, a low-complexity method for resolving stall patterns when decoding staircase codes is described. Stall patterns are the dominating contributor to the error floor in the original decoding method.

Trapping Sets of Quantum LDPC Codes [PDF]
Iterative decoders for finite length quantum low-density parity-check (QLDPC) codes are attractive because their hardware complexity scales only linearly with the number of physical qubits.

Radiant floor cooling systems are increasingly used in practice. The temperature distribution on the floor surface and inside the floor structure, especially the minimum and average temperature of floor surface, determines the thermal performance of ...
