We present an optimal sidelobe blanker (SLB) detector for Swerling-1 and Swerling-0 targets and compare the performances of the suggested detector with the classical Maisel SLB structure. The optimal SLB detector depends on the signal to noise ratio (SNR) and jammer to noise ratio (JNR) values and may not be practical for implementation in many applications. The goal of this work is to compare the Maisel structure with the optimal detector which utilizes additional information on target and jammer and assesses the performance gap between two systems. Numerical results show that the performance of Maisel SLB structure is close to the optimal detector under very practical conditions.

On localization and tracking using received signal strength measurements /
Yılmaz, Alptekin; Yılmaz, Ali Özgür; Orguner, Umut; Department of Electrical and Electronics Engineering (2015)
In this study, first, some received signal strength (RSS) based localization techniques, including maximum likelihood estimation (MLE), multidimensional scaling (MDS) and weighted least squares (WLS), are investigated and compared to each other via a simulation study within the perspective of a collaborative localization scenario. MLE using RSS measurement model, called RSS-MLE is known in the literature to be significantly biased. An important observation of this work is that the aforementioned bias can be...
On the Eigenstructure of DFT Matrices
Candan, Çağatay (Institute of Electrical and Electronics Engineers (IEEE), 2011-03-01)
The discrete Fourier transform (DFT) not only enables fast implementation of the discrete convolution operation, which is critical for the efficient processing of analog signals through digital means, but it also represents a rich and beautiful analytical structure that is interesting on its own. A typical senior-level digital signal processing (DSP) course involves a fairly detailed treatment of DFT and a list of related topics, such as circular shift, correlation, convolution operations, and the connectio...
On the Implementation of Optimal Receivers for LFM Signals using Fractional Fourier Transform
Candan, Çağatay (2008-05-30)
We present a novel receiver structure for the detection and parameter estimation of linear frequency modulated signals. The proposed structure is based on the relations between the fractional Fourier transform and the ambiguity function. It has been shown that the optimal ML receiver, which is the peak detector in the ambiguity plane, can be implemented at a reduced search complexity with the proposed method. The proposed method uses two 1-dimensional search operations in two different fractional Fourier do...
On event signal reconstruction in wireless sensor networks
Atakan, Baris; Akan, Oezguer B. (2007-05-18)
In Wireless Sensor Networks (WSN), the effective detection and reconstruction of the event signal is mainly based on the regulation of sampling and communication parameters used by the sensor nodes. The aim of this paper is to understand the effect of these parameters on the reconstruction performance of event signal in WSN. Theoretical analysis and results show that with proper selection of sampling and communication parameters, the event signal can be satisfactorily reconstructed at the sink. Furthermore,...
