Optimality of LDGM-LDPC compound codes for lossy compression of binary erasure source
We consider the Binary Erasure Source (BES) introduced by Martinian and Yedidia. Based on the technique introduced by Martinian and Wainwright, we upper bound the rate-distortion p...

Using synchronization bits to boost compression by substring enumeration
A new lossless data compression technique called compression via substring enumeration (CSE) has recently been introduced. It has been observed that CSE achieves lower performance ...

Approximating discrete probability distributions with causal dependence trees
Abstract--Chow and Liu considered the problem of approximating discrete joint distributions with dependence tree distributions where the goodness of the approximations were measure...

An achievable rate of large block-fading MIMO systems with no CSI via successive decoding
Abstract--A Rayleigh block-fading multiple-input multipleoutput (MIMO) channel with channel state information (CSI) available neither to the transmitter nor to the receiver is cons...

Spectral entropy-based bit allocation
In transform-based compression schemes, the task of choosing, quantizing, and coding the coefficients that best represent a signal is of prime importance. As a step in this directi...
