  • Pipelined Two-Operand Modular Adders 

    Czyzak, M.; Horiszny, J.; Smyk, R. (Společnost pro radioelektronické inženýrství, 2015-04)
    Pipelined two-operand modular adder (TOMA) is one of basic components used in digital signal processing (DSP) systems that use the residue number system (RNS). Such modular adders are used in binary/residue and residue/binary ...
  • RF MEMS Based Tunable Bowtie Shaped Substrate Integrated Waveguide Filter 

    Ur Rehman, M. Z.; Baharudin, Z.; Zakariya, M. A.; Khir, M. H. M.; Jilani, M. T. (Společnost pro radioelektronické inženýrství, 2015-04)
    A tunable bandpass filter based on a technique that utilizes substrate integrated waveguide (SIW) and double coupling is presented. The SIW based bandpass filter is implemented using a bowtie shaped resonator structure. ...
  • Signal Detection for QPSK Based Cognitive Radio Systems using Support Vector Machines 

    Mushtaq, M. T.; Khan, I.; Khan, M. S.; Koudelka, O. (Společnost pro radioelektronické inženýrství, 2015-04)
    Cognitive radio based network enables opportunistic dynamic spectrum access by sensing, adopting and utilizing the unused portion of licensed spectrum bands. Cognitive radio is intelligent enough to adapt the communication ...
  • A Simplified Scheme of Estimation and Cancellation of Companding Noise for Companded Multicarrier Transmission Systems 

    Peng, S.; Yuan, Z.; You, J.; Shen, Y.; Jian, W. (Společnost pro radioelektronické inženýrství, 2015-04)
    Nonlinear companding transform is an efficient method to reduce the high peak-to-average power ratio (PAPR) of multicarrier transmission systems. However, the introduced companding noise greatly degrades the bit-error-rate ...
  • Statistical Multirate High-Resolution Signal Reconstruction Using the EMD-IT Based Denoising Approach 

    Kizilkaya, A.; Ukte, A.; Elbi, M. D. (Společnost pro radioelektronické inženýrství, 2015-04)
    The reconstruction problem of a high-resolution (HR) signal from a set of its noise-corrupted low-resolution (LR) versions is considered. As a part of this problem, a hybrid method that consists of four operation units is ...
  • Uplink Multiuser MIMO Detection Scheme with Reduced Computational Complexity 

    Cho, S.; Park, S. K. (Společnost pro radioelektronické inženýrství, 2015-04)
    The wireless communication systems with multiple antennas have recently received significant attention due to their higher capacity and better immunity to fading channels as compared to single antenna systems. A fast antenna ...
  • Visible Light Communications towards 5G 

    Zvanovec, S.; Chvojka, P.; Haigh, P. A.; Ghassemlooy, Z. (Společnost pro radioelektronické inženýrství, 2015-04)
    5G networks have to offer extremely high capacity for novel streaming applications. One of the most promising approaches is to embed large numbers of co-operating small cells into the macro-cell coverage area. Alternatively, ...
  • A Wideband Direct Data Domain Genetic Algorithm Beamforming 

    Elkamchouchi, H. M.; Hassan, M. M. (Společnost pro radioelektronické inženýrství, 2015-04)
    In this paper, a wideband direct data-domain genetic algorithm beamforming is presented. Received wideband signals are decomposed to a set of narrow sub-bands using fast Fourier transform. Each sub-band is transformed to ...
  • A Wilkinson Power Divider with Harmonic Suppression and Size Reduction using High-low Impedance Resonator Cells 

    Hayati, M.; Abdipour, A.; Abdipour, A. (Společnost pro radioelektronické inženýrství, 2015-04)
    A miniaturized Wilkinson power divider using high-low impedance resonator cells are designed and fabricated. The proposed power divider occupies 23.7% of the conventional structure circuit area at the operating frequency ...
