[matlab] beylkin-sar-spie DL : 0: Many synthetic aperture radar (SAR) image formation algorithms require the computation of a multidimensional Fourier transform of irregularly-sampled or unequally-spaced data samples. We apply a recently developed algorithm, the unequally-spaced FFT (USFFT),2 to SAR image formation and compare its accuracy and complexity to a conventional algorithm. We find that the USFFT algorithm allows comparable accuracy to traditional approaches at a slightly reduced computational cost. We briefly discuss extensions of the USFFT algorithm to multiresolution SAR imaging

[matlab] ZigBeeIEEE DL : 0: The implementation was built on Matlab/Simulink using fundamental components in Simulink to demonstrate how reliably complex modulation schemes can be built, cost effectively and efficiently [5]. The design of ZigBee transmitter using MSK modulation is shown in the Figure 1. Here we map input data bits to 8-chip PN sequences to be transmitted and results in a chip rate of two mega chips per second. After that, resultant chip sequence is send to the serial to parallel converter. It is used here to separate the odd and even bit indexed chips. Following this bipolar data formatting is performed and signal modulated with a 2.4 GHz carrier on the In Phase and QuadraturePhase data stream and adds it to get the required transmitter output signal.

[matlab] 7213211Dijkstra_router DL : 0: Abstract—We propose two novel energy-aware routing algorithms for wireless ad hoc networks, called reliable minimum energy cost routing (RMECR) and reliable minimum energy routing (RMER). RMECR addresses three important requirements of ad hoc networks: energy-efficiency, reliability, and prolonging network lifetime. It considers the energy consumption and the remaining battery energy of nodes as well as quality of links to find energy-efficient and reliable routes that increase the operational lifetime of the network. RMER, on the other hand, is

[matlab] COST231 Models DL : 0: The COST 231 model [1-2] is a semi-empirical path loss model, resulting from the combination of Walfisch-Bertoni [3] and Ikegami [4] models. It is recommended for macro-cells in urban and suburban scenarios, showing very good results for path loss calculations for base station antennas located above the average roof height. However, the prediction errors increase significantly as transmitter antenna height approaches the roof height, reaching a very poor performance for transmitters located below that level. The COST 231 model has a frequency range between 800 MHz to 2000 MHz. Compared to previous models such as Okumura-Hata, the calculation procedure is more detailed, and includes four additional parameters, namely: • height of buildings • width of the roads • building separation • road orientation with respect to the direct radio path. The basic propagation loss, Lb, is calculated as the sum of three components: the free-space loss, L0, the roof-to-street loss, Lrts, produced in the street where the receiver is located, as result of the diffraction on the next rooftop; and the multiscreen diffraction loss, Lmsd, produced by multiple diffractions on the building rooftops along the direct propagation path. The model also distinguishes LOS and NLOS situations.

[matlab] easy one 2 DL : 0: The need for variable speed of an ac induction motor arises in certain industrial applications and this is often difficult to achieve because induction motors are of fixed speed. The available control techniques such as variation of supply voltage, variation of number of poles, are characterized by low efficiency and high maintenance cost. The improvement in power electronics technology through advancements in semi-conductor electronic devices with increased reliability and reduced cost led to the development of modern solid-state variable frequency motor drive which is an electronic device capable of controlling the speed of an induction motor by varying the frequency with increased efficiency, reliability and low maintenance cost
