Error-correction on non-standard communication channels
… errors and latency constraints. In this thesis, low-density parity-check codes and codes related to them are applied to non-standard channels. First, we look at time-varying noise modelled by a Markov channel. A low-density parity-check code decoder is modified to give an improvement of over 1dB. …

Fault-Tolerant Quantum Measurement of Error Syndromes and Logical Operators
… We show that on a generalized surface code family known as 2D compass codes, each stabilizer check can be fault-tolerantly measured witha single ancilla qubit, regardless of the weight of the check. Our result infers that large ancilla blocks are not always necessary for performing …

Near-capacity fixed-rate and rateless channel code constructions
Fixed-rate and rateless channel code constructions are designed for satisfying conflicting design tradeoffs, leading to codes that benefit from practical implementations, whilst offering a good bit error ratio (BER) and block error ratio (BLER) performance. More explicitly, two novel low-density …

On performance analysis and implementation issues of iterative decoding for graph based codes
There is no doubt that long random-like code has the potential to achieve good performance because of its excellent distance spectrum. However, these codes remain useless in practical applications due to the lack of decoders rendering good performance at an acceptable complexity. The invention of …
