Blending Bayesian and frequentist methods according to the precision of prior information with an application to hypothesis testing
blended inference confidence distribution confidence posterior hybrid inference maximum entropy
2011/9/30
Abstract: The following zero-sum game between nature and a statistician blends Bayesian methods with frequentist methods such as p-values and confidence intervals. Nature chooses a posterior distribut...
Scaling Behavior of Convolutional LDPC Ensembles over the BEC
Convolutional LDPC Ensembles BEC Information Theory
2011/9/2
Abstract: We study the scaling behavior of coupled sparse graph codes over the binary erasure channel. In particular, let 2L+1 be the length of the coupled chain, let M be the number of variables in e...
Nearly Doubling the Throughput of Multiuser MIMO Systems Using Codebook Tailored Limited Feedback Protocol
Multiuser MIMO Systems Limited Feedback Protocol Information Theory
2011/9/1
Abstract: We present a new robust feedback and transmit strategy for multiuser MIMO downlink communication systems, termed Rate Approximation (RA), and analyze its performance. The new scheme combines...
Interference Focusing for Simplified Optical Fiber Models with Dispersion
Simplified Optical Fiber Models Dispersion Information Theory
2011/9/1
Abstract: A discrete-time two-user interference channel model is developed that captures non-linear phenomena that arise in optical fiber communication employing wavelength-division multiplexing (WDM)...
Influence of Doppler Bin Width on GNSS Detection Probabilities
GNSS acquisition Doppler bin width receiver operating characteristics
2011/9/1
Abstract: The acquisition stage in GNSS receivers determines Doppler shifts and code phases of visible satellites. Acquisition is thus a search in two continuous dimensions, where the digital algorith...
An Interpretation of the Moore-Penrose Generalized Inverse of a Singular Fisher Information Matrix
Cramer-Rao bound constrained parameters singular Fisher information matrix
2011/9/1
Abstract: An interpretation of the Moore-Penrose generalized inverse of a singular Fisher information matrix (FIM) is presented in this paper, from the perspective of Cramer-Rao bound (CRB). CRB is a ...
Interference Networks with General Message Sets: A Random Coding Scheme
Interference Networks General Message Sets Broadcast Channel Mutiple Access Channel
2011/8/31
Abstract: In this paper, the Interference Network with General Message Sets (IN-GMS) is introduced in which several transmitters send messages to several receivers: Each subset of transmitters transmi...
Medium Access Control for Wireless Networks with Peer-to-Peer State Exchange
Medium Access Wireless Networks Peer-to-Peer State Exchange Information Theory
2011/8/31
Abstract: Distributed medium access control (MAC) protocols are proposed for wireless networks assuming that one-hop peers can periodically exchange a small amount of state information. Each station m...

2011/9/30
Abstract: This work presents a systematic study of objective evaluations of abstaining classifications using Information-Theoretic Measures (ITMs).
Measurement Design for Detecting Sparse Signals
Sparse Signals Information Theory Measurement Design
2011/8/31
Abstract: We consider the problem of testing for the presence (or detection) of an unknown sparse signal in additive white noise. Given a fixed measurement budget, much smaller than the dimension of t...
