A family of algorithms for blind equalization of QAM signals
We propose blind equalization algorithms that perform similarly to supervised ones, independently of the QAM order. They converge approximately to the Wiener solution, which gener...

SNR measurement based on linearity test for ADC BIST
—Linearity and spectral performance test contributes most cost of ADC test. This paper presents a new method for testing an ADC’s SNR from its linearity test data. The method d...

Decrypting classical cipher text using Markov chain Monte Carlo
In this paper, we present the use of Markov Chain Monte Carlo (MCMC) methods to attack the classical ciphers. We use frequency analysis as our basic tool. First we investigate the...

Interactive Volume Visualization of Complex Flow Semantics
Comprehending results from 3D CFD simulation is a difficult task. In this paper, we present a semantics-based approach to featurebased volume rendering of 3D flow data. We make ...
