Tone reservation technique combined with active constellation extension for PAPR reduction of OFDM signal
Published 2016-03-01“…To overcome the drawbacks of existing tone reservation(TR) techniques,an efficient TR algorithm combined with active constellation extension (ACE-TR) was proposed for reducing the peak-to-average power ratio (PAPR) of or-thogonal frequency division multiplexing (OFDM) signal.By means of a specially designed iterative procedure and a joint optimization approach for PAPR and bit-error-rate (BER) performances,ACE-TR was able to obtain both an im-proved BER and minimized out-of-band interference while reducing the PAPR effectively.A comprehensive theoretical analysis was presented,and some important results including the bounds of achievable PAPR gain,BER bound,and maximum iteration number were derived.Specifically,by adaptively adjusting the iterative parameters in the optimization approach,more trade-off flexibility between PAPR reduction and BER performance can be offered to satisfy various de-sign requirements.Simulations demonstrate that ACE-TR can dramatically decrease the number of required it ions to reach the desired PAPR with low computation complexity.In addition,the transmitted OFDM symbols using the pro-posed ACE-TR have less in-band distortion and lower out-of-band spectral regrowth than traditional TR algorithms.…”

Synthesis of shared aperture thinned interleaved arrays with elements in concentric rings
Published 2023-02-01“…Among planar array antennas, concentric ring array (CRA) antennas have received considerable interest since it is symmetric and provides invariant beam pattern for 360° azimuthal coverage.In case of limited antenna aperture, there is great value to thinned interleaved CRA with low peak side lobe levels and a narrow main beam.The application of the cubic interpolation and density-weighting method in shared aperture array design was demonstrated by the low peak side lobe level synthesis of CRA.By adopting the Fourier-Bessel transform the relationship between the element’s excitation and array pattern, thinned interleaved problems were formulated as time-frequency synthesis problems.On the basis of the density-weighting method, element excitations of interleaved sub-array were carefully selected in an odd-even manner, which ensured the pattern matching of the generated sub-array.The iterative FFT algo rithm was adopted to thin the concentric ring array.Simulation results show that the proposed algorithm can achieve a favorable thinned and interleaved concentric ring array design with matched power patterns and low peak sidelobe levels.The problem of thinned and interleaved concentric ring arrays is solved, and the design of multi-function shared aperture thinned interleaved arrays with elements in concentric rings is realized.…”
