    In this paper, we consider cognitive beamforming for multiple secondary data streams subject to individual signal-to-noise ratio (SNR) requirements for each secondary data stream. In such a cognitive radio system, the secondary user is permitted to use the spectrum allocated to the primary user as long as the caused interference at the primary receiver is tolerable. With both secondary SNR constra... View full abstract»

    This paper studies the optimum performance boundaries of a two-hop multi-antenna amplify-and-forward (AF) relay system with a multi-antenna energy harvesting (EH) receiver. The source and relay nodes employ orthogonal space-time block codes for data transmission. When instantaneous channel state information (CSI) is available, we design joint optimal source and relay precoders to achieve different... View full abstract»

    This paper shows, under general input data models, how block memoryless equalizers should be formulated considering reduced-redundancy transmissions for superfast detection. We propose linear and DFE-based, both multicarrier (MC) and single-carrier-frequency-domain (SC-FD) transceivers, along with efficient methods for the equalizer calculation, in a unified manner. We argue that, under a one-tap ... View full abstract»

    Consider transceiver designs in a multiuser multi-input single-output (MISO) downlink channel, where the users are to receive the same data stream simultaneously. This problem, known as physical-layer multicasting, has drawn much interest. Presently, a popularized approach is transmit beamforming, in which the beamforming optimization is handled by a rank-one approximation method called semidefini... View full abstract»

    We present a novel two-stage methodology for locating a Chemical, Biological, Radiological, or Nuclear (CBRN) source in an urban area using a network of sensors. In contrast to earlier work, our approach does not solve an inverse dispersion problem but relies on data obtained from a simulation of the CBRN dispersion to obtain probabilistic descriptors of sensor measurements under a variety of CBRN...

    This paper studies the convergence rate of a continuous-time dynamical system for l1-minimization, known as the Locally Competitive Algorithm (LCA). Solving l1-minimization problems efficiently and rapidly is of great interest to the signal processing community, as these programs have been shown to recover sparse solutions to underdetermined systems of linear equations and co...

  • A Class of Quantizers With DC-Free Quantization Noise and Optimal Immunity to Nonlinearity-Induced Spurious Tones

    Fractional- N phase-locked loops (PLLs) typically use noise-shaping coarse quantizers to control their instantaneous output frequency. The resulting quantization noise and its running sum inevitably get distorted by non-ideal analog components within the PLL, which induces undesirable spurious tones in the PLL's output signal. A recently proposed quantizer, called a successive requantizer, has bee... View full abstract»

    In this paper, we analyze spectrum sharing on broadcast primary frequency bands. We employ protection regions (with size defined by protection distances) around the broadcast transmitter service contours for meeting the primary system outage constraints, hence implementing the Federal Communications Commission's regulations. For the unlicensed nodes distributed in a Poisson Point Process, it is sh... View full abstract»

  • \ell _{p} -MUSIC: Robust Direction-of-Arrival Estimator for Impulsive Noise Environments

    A family of algorithms, named ℓp-MUSIC, for direction-of-arrival (DOA) estimation in impulsive noise is proposed. The ℓp-MUSIC estimator adopts the ℓp-norm (1 ≤ p 2) of the residual fitting error matrix as the objective function for subspace decomposition, rather than the Frobenius norm that is used in the conventional MUSIC method.

  • Time-Frequency Representation of MIMO Dynamical Systems

    Many deterministic and random physical signals can be modeled as the output of a multi-input-multi-output (MIMO) dynamical system. Since physical signals are typically nonstationary, their frequency content changes with time. To understand this time variation, we transform the MIMO system to the time-frequency domain. The result is a time-frequency MIMO dynamical system, whose input and output are... View full abstract»

  • Adaptive Processing With Signal Contaminated Training Samples

    We consider the adaptive beamforming or adaptive detection problem in the case of signal contaminated training samples, i.e., when the latter may contain a signal-like component. Since this results in a significant degradation of the signal to interference and noise ratio at the output of the adaptive filter, we investigate a scheme to jointly detect the contaminated samples and subsequently take ...

    We revisit the problem of non-coherent signal detection in multipath scattering by exploring the effect of bandwidth and signaling duration on detection performance in doubly selective rich and sparse multipath. We begin with a general sampled representation of multipath channels that allows us to quantify the independent degrees of freedom (DoF) in non-uniform and sparse channels as a function of...

    Complex Gaussian signals in engineering applications are typically noncircular, that is, they have rotation dependent distributions. However, current complex valued particle filters (PFs) have assumed (implicitly or explicitly) circular signal distributions, which for noncircular signals leads to suboptimal performance. In this correspondence, we employ a recent development in the so-called augmen... View full abstract»

    We consider the counting rate estimation of an unknown radioactive source, which emits photons at times modeled by an homogeneous Poisson process. A spectrometer converts the energy of incoming photons into electrical pulses, whose number provides a rough estimate of the intensity of the Poisson process. When the activity of the source is high, a physical phenomenon known as pileup effect distorts... View full abstract»

    We show how to use a discrete-variable factor graph for learning non-linear continuous functions from examples. The paper proposes a scheme for embedding soft quantization in a probabilistic Bayesian graph. The quantized input variables are grouped into a compound variable that is mapped through a stochastic matrix into the discrete output distribution. Specific output values are then obtained thr...

    This paper focuses on the sparse estimation in the situation where both the the sensing matrix and the measurement vector are corrupted by additive Gaussian noises. The performance bound of sparse estimation is analyzed and discussed in depth. Two types of lower bounds, the constrained Cramér-Rao bound (CCRB) and the Hammersley-Chapman-Robbins bound (HCRB), are discussed. It is shown that ... View full abstract»

    Many existing engineering works model the statistical characteristics of the entities under study as normal distributions. These models are eventually used for decision making, requiring in practice the definition of the classification region corresponding to the desired confidence level. Surprisingly enough, however, a great amount of computer vision works using multidimensional normal models lea... View full abstract»
