A Note on Scaling in Randomly Rotated Quantization and Its Connection to the CDEF +1 Pythagorean Relation
Uri Erez
Quantization schemes based on randomized rotations have recently received renewed attention, including the roles of MMSE and unbiased reconstruction scalings. In this note, we poin…
Lower Bounds on Mutual Information for Linear Codes Transmitted over Binary Input Channels, and for Information Combining
Uri Erez, Or Ordentlich, Shlomo Shamai
It has been known for a long time that the mutual information between the input sequence and output of a binary symmetric channel (BSC) is upper bounded by the mutual information b…
An Orthogonality Principle for Select-Maximum Estimation of Exponential Variables
Uri Erez, Jan Østergaard, Ram Zamir
It was recently proposed to encode the one-sided exponential source X via K parallel channels, Y1, ..., YK , such that the error signals X - Yi, i = 1,...,K, are one-sided exponent…
Incremental Refinements and Multiple Descriptions with Feedback
Jan Østergaard, Uri Erez, Ram Zamir
It is well known that independent (separate) encoding of K correlated sources may incur some rate loss compared to joint encoding, even if the decoding is done jointly. This loss i…
Super-Nyquist Rateless Coding for Intersymbol Interference Channels
Uri Erez, Gregory W. Wornell
A rateless transmission architecture is developed for communication over Gaussian intersymbol interference channels, based on the concept of super-Nyquist (SNQ) signaling. In such…
On General Lattice Quantization Noise
Tal Gariby, Uri Erez
The problem of constructing lattices such that their quantization noise approaches a desired distribution is studied. It is shown that asymptotically is the dimension, lattice quan…
