Abstract: The light extraction efficiency of a typical light-emitting diode (LED) is improved by incorporating one-dimensional ZnO nanorods. The light extraction efficiency is improved about 31% due to the waveguide effect of ZnO sub-microrods, compared to an LED without the nanorods. Other shapes of ZnO microrods and nanorods are produced using a simple non-catalytic wet chemical growth method at a low temperature on an indium-tin-oxide (ITO) top contact layer with no seed layer. The crystal morphology of a needle-like or flat top hexagonal structure and the density and size of ZnO microrods and nanorods are easily modified by controlling the pH value and growth time. The waveguide phenomenon in each ZnO rod is observed using confocal scanning electroluminescence microscopy (CSEM) and micro-electroluminescence spectra (MES).

Abstract: The present invention relates to an apparatus and method for variable fast Fourier transform. According to an embodiment of the present invention, two n-point fast Fourier transform (FFT) processors are used to generate two n-point FFT output data or one 2n-point FFT output data. The one 2n-point input data is alternately input to the two n-point FFT processors. Each of the two n-point FFT processors selects a twiddle factor for the n-point input data or the 2n-point input data and performs fast Fourier transform. A butterfly operation is performed on signals obtained by performing fast Fourier transform on the 2n-point input data signal, and the processed signals are aligned in an output order. According to this structure, it is possible to realize a fast Fourier transform hardware engine that selectively performs multi-frequency allocation in a base station system that supports the multi-frequency allocation.
