Generalized and Differential Likelihood Ratio Tests with Quantum Signal Processing

ICASSP 2019 - 2019 IEEE International Conference on Acoustics, Speech and Signal Processing (ICASSP), 2019
Quantum signal processing invokes the injection of abstract quantum mechanical frameworks into classical signal processing problems. In this work we apply this idea to the notion of optimal likelihood ratio tests within the context of the location verification problem.

Generalized Likelihood Ratios for Testing the Properness of Quaternion Gaussian Vectors

IEEE Transactions on Signal Processing, 2011
In a recent paper, the second-order statistical analysis of quaternion random vectors has shown that there exist two different kinds of quaternion widely linear processing, which are associated with the two main types of quaternion properness. In this paper, we consider the problem of determining, from a finite number of independent vector observations,

On the generalized likelihood ratio test for a class of nonlinear detection problems

IEEE Transactions on Signal Processing, 1993
The authors examine the generalized likelihood ratio test (GLRT) for a certain class of detection problems. This class is characterized by a model which is linear in some parameters and nonlinear in others. They show that the classical asymptotic analysis of the GLRT fails for this class, and demonstrate the existence of ill-behaved cases in this class.

Generalized and Average Likelihood Ratio Testing for Post Detection Integration

IEEE Transactions on Communications, 2007
In the context of spread spectrum communications, this paper investigates the use of likelihood ratio testing techniques for the design of post detection integration (PDI) methods for code acquisition in the presence of phase and frequency uncertainty.

Distributed generalized likelihood ratio tests: Fundamental limits and tradeoffs

2016 IEEE International Conference on Acoustics, Speech and Signal Processing (ICASSP), 2016
This paper focuses on the problem of distributed composite hypothesis testing in a network of sparsely interconnected agents, in which only a small section of the field modeling parametric alternatives is observable at each agent. A recursive generalized likelihood ratio test (GLRT) type algorithm in a distributed setup of the consensus-plus ...

A sequential likelihood ratio test for general hypotheses

Communications in Statistics. Part C: Sequential Analysis, 1982
In statistical inference it is often desired to test a specified funcrion of unkown parameters form an underlying distribution. Sequential procedures utilize information from the already collected observations and allow for a possible eariy termination of experimentation with a concurrent savings in time and cost. In the present work a suitable maximum-

On the generalized Viterbi algorithm using likelihood ratio testing

Proceedings IEEE International Symposium on Information Theory,, 2003
The variable size list decoder (VLD) was first discussed by Forney (1968), which selects more than one candidate message if the message passes the given criterion. Though the list decoder is seldom used for applications, it is well-known that the generalized Viterbi algorithm (GVA) employs the fixed size list decoder (FLD) in its mean process.

Improving the generalized likelihood ratio test for unknown linear gaussian channels

IEEE Transactions on Information Theory, 2003
Summary: We consider the decoding problem for unknown Gaussian linear channels. Important examples of linear channels are the intersymbol interference (ISI) channel and the diversity channel with multiple transmit and receive antennas employing space-time codes (STC).

A Reduced-Rank Generalized Likelihood-Ratio Test

1993
A generalized likelihood-ratio test (GLRT) is proposed for adaptively detecting a low rank signal in the presence of unknown strong low rank interference plus white Gaussian noise. This approach leads to a test which is closely related to the Principal Component Inverse (PCI) method of rapidly adaptive detection and extends the PCI method to the case ...

Generalized Likelihood Ratio Test Performance for Cooperative Radar-Communications

2018 52nd Asilomar Conference on Signals, Systems, and Computers, 2018
The performance of generalized likelihood ratio tests (GLRT) in radar detection is a well-studied subject, as is the performance of a maximum-likelihood decoder for a communication (comm.) receiver. The theoretical analysis of a cooperative radar-comm. receiver, however, remains an open problem.
