Deploying low-resolution (e.g. one-bit) digital-to-analog converters (DACs) is of great importance in the multiple-input multiple-output (MIMO) system equipped with a large-scale antenna array since such hardware architecture brings low-cost and circuit power saving for each antenna. In this paper, problem transmit signal design MIMO 1-bit DACs investigated. To ensure directional transmission, we propose to by minimizing weighted mean-squared error (MSE) between formed beampattern given one....
<para xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink"> The least squares-virtual ESPRIT algorithm (LS-VESPA) is extended to jointly estimate the direction-of-arrival (DOA) and ranges of multiple near-field sources impinging on an array crossed dipoles. utilizes fourth-order cumulants for direct estimation arrival angle range parameters via eigenvalues certain constructed matrices. Compared with several existing algorithms, loss aperture effectively...
With the rapid development in wireless communication technologies, interference has become a main impediment to network performance, making management (IM) critical issue. Interference steering (IS) is emerging as novel way of IM, which can steer spatial feature target subspace by exploiting interactions multiple signals over air avoid disturbance interfered receiver. In reality, there always exists interferences from single or sources. We propose three ways realize IS. The first two them...
A new method for estimating direction of arrival (DOA) the strong and weak signals is proposed in presence array gain phase mismatch. Firstly, mismatch estimated using norm error vector between practical steering theoretical signal, then data covariance matrix calibrated. Secondly, seek vectors are obtained by eigenbeamforming normalization with eigenvalues eigenvectors calibrated matrix. Finally, directions all according to spatial spectrum like MUSIC vector. The has simpler computation...
Wireless networks are usually deployed to cover more overlapping areas, experiencing severe interferences and hence making interference management essential for their viability. Interference alignment (IA) is an effective way of has thus received significant attention. With IA, at least one degree-of-freedom (DoF) should be used place the aligned interferences. However, when multiple from identical transmitter a common destination, IA not applicable under one-DoF cost constraint. If these...
In this paper, we propose a decentralized strategy to find out the linear precoding matrices for two-hop multiuser relay communication system. From game-theoretic perspective, model source allocation process as strategic noncooperative game fixing matrix and interference treating additive colored noise. Alternately, from global optimization prove that optimum follows transceiver Winner filter structure giving set of transmit matrices. Closed-form solutions are finally obtained by using our...
