Dft beam pattern matlab
WebAn efficient procedure, based on a discrete Fourier transform (DFT) expansion of planar array distributions, is described for synthesizing contoured beams in satellite antenna applications. The DFT provides a global basis set that spans over the entire array, and thus produces highly directional beam patterns to serve as corresponding local basis … WebMay 27, 2010 · In this paper, we demonstrate that when the antenna elements are uniformly spaced as well as linearly arranged, and the channels are spatially correlated, the codewords in a DFT-based …
