Degree Optimization and Stability Condition for the Min-Sum Decoder
Kapil Bhattad, Vishwambhar Rathi, Ruediger Urbanke
The min-sum (MS) algorithm is arguably the second most fundamental algorithm in the realm of message passing due to its optimality (for a tree code) with respect to the {\em block…
On the Distortion SNR Exponent of Some Layered Transmission Schemes
Kapil Bhattad, Krishna R. Narayanan, Giuseppe Caire
We consider the problem of joint source-channel coding for transmitting K samples of a complex Gaussian source over T = bK uses of a block-fading multiple input multiple output (MI…
An MSE Based Ttransfer Chart to Analyze Iterative Decoding Schemes
Kapil Bhattad, Krishna Narayanan
An alternative to extrinsic information transfer (EXIT) charts called mean squared error (MSE) charts that use a measure related to the MSE instead of mutual information is propose…
A Decision Feedback Based Scheme for Slepian-Wolf Coding of sources with Hidden Markov Correlation
Krishna R. Narayanan, Kapil Bhattad
We consider the problem of compression of two memoryless binary sources, the correlation between which is defined by a Hidden Markov Model (HMM). We propose a Decision Feedback (DF…

Minimal Network Coding for Multicast
Kapil Bhattad, Niranjan Ratnakar, Ralf Koetter +1
We give an information flow interpretation for multicasting using network coding. This generalizes the fluid model used to represent flows to a single receiver. Using the generaliz…
