LT Code Equations
The LT Code equations describe the process of encoding input symbols into an error correcting code that requires no feedback from the receiver. The mathematical process involved the development of LT Codes is important. This thesis address the issue of improving the understanding of the LT Code …

Error Correcting Codes and the Human Genome.
<p>In this work, we study error correcting codes and generalize the concepts with a view toward a novel application in the study of DNA sequences. The author investigates the possibility that an error correcting linear code could be included in the human genome through application and research. The …

Error-Correcting Codes Associated With Generalized Hadamard Matrices Over Groups
… whose elements are ±1. It is well-known that error correcting codes having large minimum distance between codewords can be associated with these Hadamard matrices. Indeed, the success of early Mars deep-space probes was strongly dependent upon this communication technology.</p> <p>The concept …

Quantum codes on Hurwitz surfaces
Ever since the birth of the first quantum error correcting code, many error correcting techniques and formalism has been constructed so far. Among those, generating a quantum code on a locally planar geometry have lead to some interesting classes of codes. Main idea of this thesis stems from …

Coding performance on satellite channels using AX.25 protocol
… insure that data is received correctly, certain error control strategies are employed. In packetized transmission, automatic-repeat-request (ARQ) schemes and error correcting codes have been employed. Currently a combination of both is not employed by the AX.25 protocol. The purpose of this …

Decoding error-correcting codes via linear programming
Error-correcting codes are fundamental tools used to transmit digital information over unreliable channels. Their study goes back to the work of Hamming [Ham50] and Shannon [Sha48], who used them as the basis for the field of information theory. The problem of decoding the original information up …

Fault tolerance issues in nanoelectronics
… is to investigate the problem of transient errors in nanoelectronic devices. Transient error rates for a selection of nanoelectronic gates, based upon quantum cellular automata and single electron devices, in which the electrostatic interaction between electrons is used to create Boolean …

A combined approach for hiding partial information in RSA
… this should be feasible. The second scheme uses error-correcting codes for accommodating the random component. The plaintext is processed with an error-correcting code and deliberately corrupted before encryption. The introduced corruption lies within the error-correcting ability of the code, so …

Complexity and second moment of the mathematical theory of communication
The performance of an error correcting code is evaluated by its block error probability, code rate, and encoding and decoding complexity. The performance of a series of codes is evaluated by, as the block lengths approach infinity, whether their block error probabilities decay to zero, whether …

Verifying quantum proofs with entangled games
… value of a nonlocal game up to constant error, proving the quantum entangled games PCP conjecture of Fitzsimons and Vidick. Our main technical innovations are two constructions of robust self-tests for entanglement: two-player nonlocal games where to succeed with probability E-close to 1, …

Cyclostationary Methods for Communication and Signal Detection Under Interference
… filter is developed and its Minimum Mean Squared Error (MMSE) filter weights are found. The repetition of data symbols and their optimal combining with the TV-FRESH filter creates an effect of improving the Bit Error Rate (BER) at the receiver, similar to an error correcting code. The important …

Coding for emerging archival storage media
… in a rapid stage of research and development. Error Correcting Codes and coding schemes must be designed for these emerging media’s constraints and noise characteristics, similar to the large body of work on coding for communication applications. Unlike communication standards, digital data …
