The above simulations show that the roughness of the 3D fractal surface can be characterized by the mean slope between the main lobe of function [absolute value of [gamma](k)] and the first two side-lobes, adjacent to the main lobe (see Fig.
Both surface and volume model exhibit relatively good agreement of radiation pattern trace in the main lobe, as seen in Fig.
The azimuth resolution is typically defined as the 3-dB-level width of the main lobe of the SAP.
Next, consider an array with the main lobe steered to 40[degrees] from broadside and apply four-element pattern as before.
This problem is resolved with the proposed window function by the author based on the Elliptical Trigonometry in which we can regulate the shape of the window to obtain a very smooth form within the window function and obtain at the same time a wider main lobe and very small side lobes in magnitude.
where: [DELTA]T = time difference between the time sidelobes and the main lobe
As shown in Figure 2, the main lobe is "twice the bit rate" wide (converted to RF at 1 Hz per bps).
The proprietary technology delivers greater than 30 dB of attenuation at all angles outside of the main lobe.
as the roughness of the fractal surface increases, the emerging slope between the main lobe and the side lobes also increases.
The main lobe width of MOR filter is same as that of the Rectangular filter to preserve the details and edges on the reconstructed images.
The performance of an OFDM system can be degraded due to time synchronization errors, increased amount of inter modulation distortion called high Peak-to- Average Power Ratio (PAPR), phase noise and most importantly high energy side-lobes that are only 15 dB lower than the main lobe [1,2,7-11].
