Design And Learning-Based Decoding Of Low-Density-Parity-Check Codes For Multiterminal Communication, Salman Habib

Dissertations

The field of information theory was initiated by Claude Shannon in 1948. According to his most notable work, data can be transmitted reliably over a noisy communication channel with high probability, as long as a suitable coding scheme is employed to protect the data from channel noise. Since then, coding theorists have made numerous attempts to design low-complexity error correcting schemes which achieve the Shannon limit.

In the 1960s, Robert Gallager introduced sparse graph-based low-density-parity-check (LDPC) codes which are practically suitable for various coding applications, mainly due to their low encoding and decoding complexity compared to classical codes (e.g., Reed-Muller …

This study explores four primary English teachers' agentive perspectives about assessment in their schools. Given the challenges brought by the abolition of International Standard School (ISS), the changed status of the school, and the exclusion of English from the 2013 National Education Curriculum (NEC), a teacher-based assessment was the only solution to the unavailability of assessment guidelines and the unsuitability of assessment materials and methods. Employing teacher agency theory, this study examines the agentive sides of the teachers' perspectives as they would represent the teachers' strategic solutions toward the school's emerging problems. The teacher-based assessment was expected to accommodate the …
