    In this study, we provide comparative analysis of the so-called “threshold conditions” for conditional (deterministic, CML) and unconditional (stochastic, UML) maximum likelihood estimation. Specifically, we analyze SNR and sample support values where the accurate UML and CML DoA estimation starts to rapidly divert from the Cramér-Rao bound (CRB) due to the onset of severely ...

  • Aspects of threshold region mean squared error prediction: Method of interval errors, bounds, Taylor's theorem and extensions

    Publication Year: 2012, Page(s):13 - 17

    The method of interval errors (MIE) predicts mean-squared error (MSE) performance at low signal-to-noise ratios (SNR) where global errors dominate. It is algorithm specific and enabled by an estimate of asymptotic MSE performance and sidelobe error probabilities. Parameter bounds are adequate representations of the asymptotic MSE in absence of signal model mismatch, but Taylor theorem can account ... View full abstract»

  • Lower bounds on the MSE for mixed far-field and near-field sources direction-of-arrivals

    Publication Year: 2012, Page(s):18 - 22
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (303 KB) | HTML iconHTML

    Fundamental limits in terms of mean square error for source localization by an array of sensors are investigated. The context is the case of a far-field source and a near-field source for which few results are available. Particularly, in order to characterize the SNR threshold exhibited by estimators in such scenario, lower bounds other than the Cramér-Rao bound are studied. View full abstract»

  • On the resolvability of closely spaced targets using a colocated MIMO radar

    The resolvability of two closely spaced targets is an important performance measure in a MIMO radar problem. In this paper, we investigate the minimum signal-to-noise ratio, commonly referred to as the signal-to-noise ratio threshold, required to resolve a known target from an unknown target using a colocated MIMO radar. Toward this goal, we conduct a generalized likelihood ratio test w.r.t. the s... View full abstract»

  • Understanding the impact of phase noise on active cancellation in wireless full-duplex

    Practical designs of wireless full-duplex are made feasible by reducing self-interference via active and passive methods. However, extending the range to long-range communication remains a challenge, primarily due to residual self-interference even after a combination of active cancellation and passive suppression methods is employed. In this paper, we study the factor that limits the amount of ac... View full abstract»

  • Hardware phenomenological effects on cochannel full-duplex MIMO relay performance

    In this paper, the performance of cochannel full-duplex multiple-input multiple-output (MIMO) nodes is considered in the context of models for realistic hardware characteristics. Here, cochannel full-duplex relay indicates a node that transmits and receives simultaneously in the same frequency band. It is assumed that transmit and receive phase centers are physically distinct, enabling adaptive sp... View full abstract»

    Recent work has shown the possibility of implementing full-duplex wireless radios using commodity hardware. We discuss the possibility of extending full-duplex designs to support multiple input, multiple output (MIMO) systems. We explore how such a design could lead to a rethinking of wireless networks. We discuss various applications of full-duplex radios and the gains possible with those applica... View full abstract»

  • Analog and digital self-interference cancellation in full-duplex MIMO-OFDM transceivers with limited resolution in A/D conversion

    We analyze the performance of full-duplex MIMO-OFDM transceivers with subtractive self-interference cancellation in analog and/or digital domain, i.e., before and/or after analog-to-digital converters (ADCs). In particular, the non-ideal ADCs are modeled by assuming uniform b-bit quantization which allows us to derive closed-form expressions for the signal to interference and noise ratio when incl...

    This paper considers the broadcast channel with an energy harvesting transmitter equipped with an inefficient energy storage device. For this setting, the optimal offline power policy that maximizes the average weighted sum rate of the system is derived. It is observed that this policy has a double threshold structure, with piecewise constant thresholds determined by the energy harvesting process.... View full abstract»

    We study the capacity regions of two-way and multiple-access energy harvesting communication systems with one-way wireless energy transfer. In these systems, energy required for data transmission is harvested by the users from nature throughout the communication duration, and there is a separate unit that enables energy transfer from the first user to the second user with an efficiency of α...

    A broadcast model in which the transmitter sends confidential and common messages to two receivers is considered. It is assumed that the common and confidential data is stored in buffers prior to transmission and the transmitter operates under constraints on buffer violation probability. Under such constraints, effective capacity formulation is employed to determine the throughput. Moreover, energ... View full abstract»

    Future low cost wireless networks are expected to provide high data rates with low power consumption. A dense deployment of distributed small-cells, within the existing network infrastructure, is one of the candidate solutions to achieve this goal. Unfortunately, the aggregate signal resulting from the transmission of these multiples small cells can be considered as an electromagnetic (EM) polluti... View full abstract»
