Performance comparison of message passing decoding algorithms for binary and non-binary low density parity check (LDPC) codes
Uzunoğlu, Cihan; Yücel, Melek D; Department of Electrical and Electronics Engineering (2007)
In this thesis, we investigate the basics of Low-Density Parity-Check (LDPC) codes over binary and non-binary alphabets. We especially focus on the message passing decoding algorithms, which have different message definitions such as a posteriori probabilities, log-likelihood ratios and Fourier transforms of probabilities. We present the simulation results that compare the performances of small block length binary and non-binary LDPC codes, which have regular and irregular structures over GF(2),GF(4) and GF...
Performance analysis of elliptic curve multiplication algorithms for elliptic curve cryptography
Özcan, Ayça Bahar; Yücel, Melek D; Department of Electrical and Electronics Engineering (2006)
Elliptic curve cryptography (ECC) has been introduced as a public-key cryptosystem, which offers smaller key sizes than the other known public-key systems at equivalent security level. The key size advantage of ECC provides faster computations, less memory consumption, less processing power and efficient bandwidth usage. These properties make ECC attractive especially for the next generation public-key cryptosystems. The implementation of ECC involves so many arithmetic operations; one of them is the ellipt...
Performance evaluation of similarity measures for dense multimodal stereovision
Yaman, Mustafa; Kalkan, Sinan (SPIE-Intl Soc Optical Eng, 2016-05-01)
Multimodal imaging systems have recently been drawing attention in fields such as medical imaging, remote sensing, and video surveillance systems. In such systems, estimating depth has become possible due to the promising progress of multimodal matching techniques. We perform a systematic performance evaluation of similarity measures frequently used in the literature for dense multimodal stereovision. The evaluated measures include mutual information (MI), sum of squared distances, normalized cross-correlat...
