Application of Time Modulation in the Synthesis of Sum and Difference Patterns by Using Linear Arrays
(John Wiley & Sons, Inc., 2006-05)
[Abstract] In this paper, time modulation is applied to a small number of elements of a linear array that radiates either sum or difference patterns, in order to take control over their sidelobe levels. The simulated ...
A comparative study of STBC transmissions at 2.4 GHz over indoor channels using a 2 × 2 MIMO testbed
(Hindawi, 2008)
[Abstract]: In this paper we employ a 2 × 2 Multiple-Input Multiple-Output (MIMO) hardware platform to evaluate, in realistic indoor scenarios, the performance of different space-time block coded (STBC) transmissions at ...
Blind channel identification in Alamouti coded systems: a comparative study of eigendecomposition methods in indoor transmissions at 2.4 GHz
(Wiley, 2008)
[Abstract]: This paper focuses on blind channel estimation in Alamouti coded systems with one receiving antenna working in indoor scenarios where the flat fading assumption is reasonable. A comparative study of several ...
Synthesis of Multiple-Pattern Planar Antenna Arrays with Single Prefixed or Jointly Optimized Amplitude Distributions
(John Wiley & Sons, Inc., 2002-01-05)
[Abstract] Previous work on the generation of multiple radiation patterns by a single linear array antenna with an unchanging excitation amplitude distribution is generalized to planar arrays. The amplitude distribution ...
Measurement Effects on Ø-Symmetric Shaped Patterns Generated by Circular Continuous Apertures
(Institute of Electrical and Electronics Engineers, 2003-10)
[Abstract] Sidelobe-level and ripple behaviors of Ø-symmetric shaped patterns, generated by circular, real and complex, continuous Taylor distributions, is analyzed as a function of measurement distances. This paper reveals ...
Effects of Measurement Distance on Measurements of Symmetrically Shaped Patterns Generated by Line Sources
(Institute of Electrical and Electronics Engineers, 2003-02)
[Abstract] Symmetrically shaped patterns, generated by real continuous linear apertures derived from Taylor distributions, resemble Taylor sum patterns in regard to the distance-dependence of their sidelobe heights. Their ...
Visualizing the 3D Polar Power Patterns and Excitations of Planar Arrays with Matlab
(Institute of Electrical and Electronics Engineers, 2004-04)
[Abstrac] This paper discusses the use of Matlab to create three-dimensional polar plots of the power patterns of planar arrays together with 3D plots of the amplitudes and phases of their excitations. A few lines of Matlab ...
Near Field Quasi-Null Control with Far Field Sidelobe Level Maintenance in Line Source Difference Patterns
(Taylor & Francis, 2003)
[Abstract] A previously developed method to place a quasi-null in a specified angular position of the near-field line source in sum patterns while, simultaneously, the far-field sidelobe level is maintained under a desired ...
