Classical error correcting codes: innovative sampling methods
Estimation of very low BER in LDPC based digital communication systems
The quality of transmission in digital communication systems is usually measured by Frame Error Rate (FER). The time taken by standard Monte Carlo (MC) simulation to estimate the FER increases exponentially with the increase in Signal-to-Noise Ratio (SNR). With PhD student Shahkar Kakakhail (2006-2009, co-advisor David...
Statistical Physics of Spin Models with Long-Ranged Interactions
Algebraically decaying interactions
One of the fundamental question that pertains to spin models governed by long-ranged interactions is the influence of the interaction range on their critical behavior. Two of the most challenging issues when investigating these models by means of stochastic (Monte Carlo) methods are:
the onset of a diversity of phase transitions as the decay parameter is...
