Abstract:

This paper compares seemingly similar words from a variety of acting teachers, and shows how it is impossible to draw clear comparisons between words that are often used as synonyms. The paper is a reflection of the journey from believing in translation to recognizing its impossibility. In Chapter 1 we focus on one of the most common elements in actor training, Attention/focus/concentration, and analyze the shades of meaning in those words and the difficulty of talking about them in isolation. In Chapter 2 we look at the way in which semiotic analysis can explain the words resistance to equiva

Abstract:

Stemming from previous studies on flexible LDPC decoders, this thesis work has been mainly focused on the development of flexible turbo and LDPC decoder designs, and on the narrowing of the power, area and speed gap they might present with respect to dedicated solutions. Additional studies have been carried out within the field of increased code performance and of decoder resiliency to hardware errors. The first chapter regroups several main contributions in the design and implementation of flexible channel decoders. The first part concerns the design of a Network-on-Chip (NoC) serving as an

Abstract:

The growing popularity of a class of linear block codes called the low-density parity-check (LDPC) codes can be attributed to the low complexity of the iterative decoders, and their potential to achieve performance very close to the Shannon capacity. This makes them an attractive candidate for ECC applications in communication systems. This report proposes methods to systematically construct regular and irregular LDPC codes.A class of regular LDPC codes are constructed from incidence structures in finite geometries like projective geometry and affine geometry.

Steady-state visual evoked potential (SSVEP)-based brain-computer interfaces(BCIs) have been widely investigated.

In addition to CCA algorithms, convolutional neural networks(CCNs) also improve the performance of SSVEP-based BCIs by generalizing well on the frequency features of the EEG signals.

When a demanding video decoding task requires more CPU resources then available, playback degrades ungracefully today: The decoder skips frames selected arbitrarily or by simple heuristics, which is noticed by the viewer as jerky motion in the good case or as images completely breaking up in the bad case.

Many research papers have investigated the performance of NC-aided networks such as throughput and outage capacity. However, the analysis of NC in practical systems where NC is combined with other techniques such as channel coding is still immature to fully understand its potential performance.

Abstract:

The Low-Density Parity-Check (LDPC) codes, which were invented by Gallager back in 1960s, have attracted considerable attentions recently. Compared with other error correction codes, LDPC codes are well suited for wireless, optical, and magnetic recording systems due to their near- Shannon-limit error-correcting capacity, high intrinsic parallelism and high-throughput potentials. With these remarkable characteristics, LDPC codes have been adopted in several recent communication standards such as 802.11n (Wi-Fi), 802.16e (WiMax), 802.15.3c (WPAN), DVB-S2 and CMMB.

Low-density parity check (LDPC) codes have experienced tremendous popularity due to their capacity-achieving performance. In this dissertation, several different aspects of LDPC coding and its applications to magnetic storage are investigated. One of the most significant issues that impedes the use of LDPC codes in many systems is the error-rate floor phenomenon associated with their iterative decoders. By delineating the fundamental principles, we extend to partial response channels algorithms for predicting the error rate performance in the floor region for the binary-input AWGN channel. We

Le calcul quantique tolérant aux fautes est un ensemble de techniques dont le but est d'effectuer des calculs quantiques de manière fiable en utilisant des composants bruités. Dans ce contexte, l'utilisation de codes correcteurs quantiques maintient le nombre d'erreurs présentes dans le système en dessous d'un seuil tolérable. L'un des principaux problèmes de ce domaine est d'évaluer le coût minimum (en mémoire et en temps) nécessaire pour transformer un calcul quantique idéal en un calcul tolérant aux fautes. Dans cette thèse, nous montrons que la famille des codes expanseurs quantiques assoc

碩士<br>國立雲林科技大學<br>電機工程系<br>107<br>This thesis mainly analyzes the performance of successive cancellation list (SCL) decoder and CRC aided-successive cancellation list (CA-SCL) decoder for polar code.，SCL decoder can be considered as the improved version of a successive cancellation (SC) decoder. Since SC decoder requires the estimate of previous information bits when dealing with current ones, serious error propagation will occur under erroneous decision. SCL decoder has been focused on the improvement on the drawbacks of SC. Besides the operations carried out in SC decoder, SCL calculates the

碩士<br>中原大學<br>電機工程研究所<br>90<br>Abstract In this thesis, the main ideas are investigating the performance of turbo codes applying SOVA (Soft Output Viterbi Algorithm) in wireless communication systems. Comparing with MAP (Maximum A Posteriori Algorithm), the advantage of SOVA is providing a low complexity decoder. We propose four methods to improve the performance of SOVA decoding. The simulation results verify that these methods improve the performance of original SOVA.
