We show that an increase in uncertainty about the probability of being audited (ambiguity) increases tax compliance for ambiguity-averse taxpayers but reduces compliance for ambiguity lovers. Because experimental evidence reveals considerable heterogeneity with respect to ambiguity preferences, we conclude that fostering uncertainty about the probability of being audited may not be an effective...

2. QUADRATIC TIME-FREQUENCY DISTRIBUTIONS AND AMBIGUITY FUNCTION In this paper, the properties Of the recently Proposed B-distribution are investigated. We show that this distribution satisfies most of the desirable properties sought for a time-frequency distribution. Quadratic (also known as Cohen’s) class of time-frequency distributions is defined by the following expression [31: That is, we ...

ambiguity is one of very important techniques in persian rhetoric, but in spite of its importance, it seems there is not enough accuracy in its definition and types.  the present essay tries to redefine the concept of ambiguity. we will begin by analyzing the definitions of ambiguity and amphiboly according to the old and new persian sources; then we presents a new definition and review and ana...

We present a survey on the current status of the constructions of polyphase sequences with low correlation, discrete Fourier transform (DFT), and ambiguity in both time and phase domain, including some new insights and results. Firstly, we systematically introduce the concepts of phase-shift operators and ambiguity functions of sequences, and give a new construction of polyphase sequences from ...

Linear combinations of the carrier phase data which are independent of the ionospheric delays are referred to as ionosphere-free linear phase combinations. In the dual frequency case there exists only one such combination which at the same time ensures the integer estimability of the ambiguities. In the triple-frequency case there is a whole class of such linear combinations. We identify this c...

An algorithm of solving phase ambiguity of multi-baseline direction finding system based on sparse uniform circular array is proposed in this paper. This sparse uniform circular array whose inter-element spacing is larger than half-wavelength distance suffers from cyclic phase ambiguities, which may cause estimation errors. In order to solve the above phase ambiguities, the corresponding virtua...

I have designed, built, and evaluated a passive radiolocation system that uses only signals of opportunity, that is, signals that exist for purposes other than radiolocation. The system estimates the relative position vector between a base station, which is a navigation receiver at a known location, and a rover, which is like the base station but free to move about. The relative position vector...

Existing adaptive algorithms for blind SIMO system identification are implicitly derived for real signals. In this paper, we extend the multichannel LMS algorithm to the complex case. This is useful, for example, in multirate implementations of the algorithms where the subband signals are usually complex. With this algorithm, the channels are identified correctly up to a complex multiplicative ...

Resolving the GPS carrier-phase ambiguities has been a continuing challenge for sub-centimeter-level highprecision GPS positioning. Once the integer ambiguities are fixed correctly, the carrier-phase observations are conceptually turned into sub-centimeter-level high-precision range measurements making it possible to attain high-precision positioning solutions. Consequently, this topic has been...

We explore the possibility of using an emerging tool in statistical signal processing, sequential importance sampling (SIS), for joint estimation and decoding of space-time trellis codes (STTC). First, we provide background on SIS, and then we discuss its application to space-time trellis code (STTC) systems. It is shown through simulations that SIS is suitable for joint estimation and decoding...
