Clipping-Based Iterative PAPR-Reduction Techniques for FBMC

OFDM 2012; 17th International OFDM Workshop 2012 (InOWo'12), 2012

Orthogonal Frequency Division Multiplexing (OFDM) is the most favored modulation technique in multicarrier wireless communications. Recently, the Filter Bank Multicarrier (FBMC) modulation scheme has drawn attention due its low Adjacent Channel Leakage Ratio (ACLR), which makes it especially suitable for Cognitive Radio (CR) applications. In multicarrier schemes the large dynamic range of the signal is a common problem, both FBMC ...

  • Clipping-Based Iterative PAPR-Reduction Techniques for FBMC

    Orthogonal Frequency Division Multiplexing (OFDM) is the most favored modulation technique in multicarrier wireless communications. Recently, the Filter Bank Multicarrier (FBMC) modulation scheme has drawn attention due its low Adjacent Channel Leakage Ratio (ACLR), which makes it especially suitable for Cognitive Radio (CR) applications. In multicarrier schemes the large dynamic range of the signal is a common problem, both FBMC and OFDM signals have high Peak-to-Average Power Ratio (PAPR). If nonlinear distortions are present, this large PAPR can lead to spectral regrowth causing harmful interference in the neighboring frequency bands. In this paper clippingbased PAPR-reduction schemes aided to reduce the PAPR of FBMC signal are presented. A comparison is given for both transmitter and receiver oriented methods. Index Terms - FBMC, PAPR-reduction, Clipping, Iterative.

  • Fuzzy adaptive signal predistorter for OFDM systems

    This work develops an adaptive High Power Amplifier (HPA) predistorter that applies the fuzzy logic and fuzzy set theory. As Volterra and Fourier series models or Neural Networks, a fuzzy logic system (FLS) is a nonlinear function approximated and we demonstrate its ability to compensate the nonlinear distortions for orthogonal multicarrier transmitters and relay stations. When compared with Volterra or Fourier Series predistorters, the main features of the fuzzy predistorter are low computational complexity and simple design. The good performance of the proposed predistorter is compared with that of a Fourier Series predistorter via simulations applied to the DVB (Digital Video Broadcasting) standard.

  • Multi-Input Distortion Analysis of Nonlinear Integrated Circuits

    In this work we present a method for the multi-input distortion analysis of nonlinear integrated circuits. For this purpose we adopt the method of series reversion to obtain an approximative solution of the network equations arising by means of the modified nodal analysis. The proposed method determines a series expansion of the output signal in terms of the nominal input signal and a distortion signal at an arbitrary input port. From this expansion it is possible to calculate analytical expressions of the spectral components arising from intermodulations between both inputs.

  • New planar distributed devices based on a domain principle

    The spacial aspects of bipolar planar circuits are usually of only incidental interest, and are not considered until the layout stage. The devices that constitute the total circuit require attention to geometry, but electrically can be regarded as point-like elements. Structure and function arise from interconnecting these pre-characterized elements.

  • AMS system simulation techniques

    As integrated circuits become more complex and more difficult to design and verify prior to fabrication, evermore sophisticated simulation techniques are being developed to meet the design challenges, with particular emphasis on behavioral modeling and simulation. This session presents five papers describing new simulation techniques for analog mixed-signal systems.

  • Trends in Wireless Communications

    This chapter includes a summary of the history and recent trends in wireless communications especially on mobile cellular systems. The basic transmission problems and solutions are summarized in the physical and network layers. The fundamental limits define the upper performance bounds for spectral and energy efficiency. Regulation and standardization is needed so that the finite frequency resource is used efficiently, and the systems work together even in different continents. We expect that in the future the radio systems will be more intelligent but the level of cognition will depend on the available energy resources.

  • Write equalization in future tape channels

    The characteristics of advanced write- and nonequalized tape channels have been modeled and evaluated to investigate the impact of the equalization on future tape channels, realizing that several factors regarding write- equalization (WE) should be taken into account. It is found that the use of WE can improve nonlinear distortion in the write process and reduce read- equalizer requirements even for media with a moment (M/sub R//spl delta/) as low as 1 memu/cm/sup 2/, and may therefore continue to offer advantages to future thin metal-particle tape systems.
