A Novel Low-Complexity Precoded OFDM System With Reduced PAPR

Sen-Hung Wang; Chih-Peng Li; Kuan-Chou Lee; Hsuan-Jung Su IEEE Transactions on Signal Processing, 2015

The computational complexity and peak-to-average power ratio (PAPR) of conventional precoded orthogonal frequency division multiplexing (OFDM) systems can be reduced using a T-OFDM precoded system based on the Walsh- Hadamard matrix. The present paper proposes a novel precoding scheme for further reducing the computational complexity and PAPR of T-OFDM. In the proposed scheme, the precoding matrix is combined with an ...


Channel estimation for MIMO-OFDM using complementary codes

Michael D. Zoltowski; Tariq R. Qureshi; Robert Calderbank 2009 IEEE Radio and Wireless Symposium, 2009

We present a pilot-assisted method for estimating the frequency selective channel in a MIMO-OFDM (Multiple Input Multiple Output - Orthogonal Frequency Division Multiplexing) system. The pilot sequence is designed using the DFT (Discrete Fourier Transform) of the Golay complementary sequences. Novel exploitation of the perfect autocorrelation property of the Golay codes, in conjunction with OSTBC (Orthogonal Space-Time Block Code) based ...


Uplink reference signal design for GEO dual-polarized MIMO satellite LTE communication system

Bo Qiang; Lixin Gu; Bin Jiang; Xiqi Gao 2014 IEEE/CIC International Conference on Communications in China (ICCC), 2014

In this paper, we propose a new uplink reference signal (RS) structure and channel estimation scheme for long term evolution (LTE) compatible geostationary earth orbit (GEO) satellite communication systems over dual- polarized multiple-input multiple-output (MIMO) channels. The conventional discrete Fourier transform (DFT) based least square (LS) channel estimator suffers from a spectral leakage, which results in an irreducible inter-antenna interference ...


Interharmonics analysis using Fourier Transform and virtual instrumentation

Anca Miron; M. Chindris; A. Cziker 2009 10th International Conference on Electrical Power Quality and Utilisation, 2009

Interharmonics represent those electrical signals whose frequencies are not integer multiples of the supply fundamental frequency. They correspond to electrical components that are not synchronized with the systems fundamental frequency; due to this fact, they have a more destructive impact than harmonics on the elements of the power system. International organizations like IEC and IEEE International Force Task Committee have ...


On the Statistics of IEC 61000-4-7 Distortion Factors in Power Supply Systems

D. Bellan Instrumentation, Measurement, Computer, Communication and Control, 2011 First International Conference on, 2011

This work deals with the analytical derivation of the statistical properties of the distortion factors defined in the Standard IEC 61000-4-7 regarding harmonics and interharmonics measurements and instrumentation for power supply systems and equipment connected thereto. The statistical characterization is provided in terms of probability density function, cumulative distribution function, and statistical moments by exploiting the properties of noise propagation ...
