On the information rate of speech communication
2017 IEEE International Conference on Acoustics, Speech and Signal Processing (ICASSP), 2017The key to the success of speech-based technology is an understanding of human speech communication. While significant advances have been made, a unified theory of speech communication that is both comprehensive and quantitative is yet to emerge. In this paper we approach speech communication from an information theoretical perspective. Without relying

A new interpretation of information rate
IEEE Transactions on Information Theory, 1956If the input symbols to a communication channel represent the outcomes of a chance event on which bets are available at odds consistent with their probabilities (i.e., "fair" odds), a gambler can use the knowledge given him by the received symbols to cause his money to grow exponentially.

Before proceeding to generalizations of the various measures of information, entropy, and divergence to nondiscrete alphabets, we consider several properties of information and entropy rates of finite alphabet processes. We show that codes that produce similar outputs with high probability yield similar rates and that entropy and information rate, like

Information Rates Subject to State Masking
IEEE Transactions on Information Theory, 2006We consider the problem of rate-R, channel coding with causal/noncausal side information at the transmitter, under an additional requirement of minimizing the amount of information that can be learned from the channel output about the state sequence, which is defined in terms of the mutual information between the state sequence and the channel output ...

Information rates of Wiener processes
IEEE Transactions on Information Theory, 1970Summary: Rate distortion functions are calculated for time discrete and time continuous Wiener processes with respect to the mean squared error criterion. In the time discrete case, we find the interesting result that, for \(0 \leq D \leq \sigma ^2 /4\), \(R(D)\) for the Wiener process is identical to \(R(D)\) for the sequence of zero mean independent ...

Information rates in sampling and quantization
IEEE Transactions on Information Theory, 1967A computer-aided analysis of a digital communications system has been conducted. Salient results compare the performance of approximately optimum PCM systems with the rate-distortion function, under the assumptions of Gaussian inputs and mean-square-error distortion measure.

Information rates of autoregressive processes
IEEE Transactions on Information Theory, 1970Summary: The rate distortion function \(R(D)\) is calculated for two time-discrete autoregressive sources--the time-discrete Gaussian autoregressive source with a mean-square-error fidelity criterion and the binary-symmetric first-order Markov source with an average probability-of-error per bit fidelity criterion. In both cases it is shown that \(R(D)\)

Information rates for Poisson sequences
IEEE Transactions on Information Theory, 1973The rate-distortion function of a Poisson sequence, under a single-letter magnitude-error distortion measure is derived and studied. Simple approximations to the rate-distortion curve for low and high distortions are obtained. A useful lower bound to this curve is derived and an upper bound is generated by a simple instrumentable coding scheme.

Increased information rate by oversampling
IEEE Transactions on Information Theory, 1993A noiseless ideal low-pass filter, followed by a limiter, is normally used as a binary data channel by sampling the output once per Nyquist interval. Detectors that sample more often encounter intersymbol interference, but can be used in ways that increase the information rate.
