Source Codes as Random Number Generators
—A random number generator generates fair coin flips by processing deterministically an arbitrary source of nonideal randomness. An optimal random number generator generates asy...

Impact of Correlation on Linear Precoding in QSTBC Coded Systems with Linear MSE Detection
— In this paper, we study a wireless multiple-input multiple-output system in a Rayleigh flat-fading environment with correlation among the transmit antennas. We assume that the...

Formulations and Reformulations in Integer Programming
Creating good integer programming formulations had, as a basic axiom, the rule “Find formulations with tighter linear relaxations”. This rule, while useful when using unsophist...

Linear Joint Source-Channel Coding for Gaussian Sources through Fading Channels
Abstract— We consider the linear coding of a discrete memoryless Gaussian source transmitted through a discrete memoryless fading channel with additive white Gaussian noise (AWGN)...

Progressive fractal coding
Progressive coding is an important feature of compression schemes. Wavelet coders are well suited for this purpose because the wavelet coefficients can be naturally ordered accord...
