A new achievable rate region for the interference channel
A new achievable rate region for the general interference channel which extends previous results is presented and evaluated and the capacity of a class of Gaussian interference channels is established.
A unified achievable rate region for a general class of multiterminal source coding systems
A unified treatment of a large class of multiterminal noiseless source coding problems including all previously studied situations is presented. A unified achievable rate region is established for
Identifiability of hidden Markov information sources and their minimum degrees of freedom
The identifiability problem is completely solved by linear algebra, where a block structure of a Markov transition matrix plays a fundamental role, and from which the minimum degree of freedom for a source is revealed.
Exponential-type error probabilities for multiterminal hypothesis testing
Multiterminal hypothesis testing is considered, subject to the exponential-type constraint alpha /sub n/ >
Noise Thresholds for Discrete LDPC Decoding Mappings
For decoding low-density parity-check (LDPC) codes on discrete memoryless channels, a method to quantize messages and to find message-passing decoding functions for the variable and check nodes is developed and noise thresholds close to those of belief propagation are obtained.
A dichotomy of functions F(X, Y) of correlated sources (X, Y)
The necessary and sufficient condition for the set of all achievable rates to coincide with the Slepian-Wolf region whenever the probability density p(x, y) is positive for all (x,y) is established.
The strong converse theorem for hypothesis testing
The authors present the answer to a so-called converse problem by giving the explicit form of the power exponent. This strong converse should be regarded as completing a weak converse previously
A Further Consideration on the HK and the CMG regions for the Interference Channel
We present a simplified form of the HK (= HanKobayashi) achievable rate region for the general interference channel by using Fourier-Motzkin algorithm, as well as a simplified form of the HK region
