In fifth generation wireless networks, the escalating teletraffic and energy consumption has
necessitated the development of green communication techniques in order to further …

One of the challenging issues for Orthogonal Frequency Division Multiplexing (OFDM)
system is its high Peak-to-Average Power Ratio (PAPR). In this paper, we review and …

Orthogonal frequency division multiplexing (OFDM) is a modulation technique which is now
used in most new and emerging broadband wired and wireless communication systems …

We present the joint maximum likelihood (ML) symbol-time and carrier-frequency offset
estimator in orthogonal frequency-division multiplexing (OFDM) systems. Redundant …

The distribution of the peak-to-average power ratio (PAPR) in strictly band-limited
orthogonal frequency-division multiplexing (OFDM) signals is studied. Assuming that the …

Relying on basic tools such as eigensignals of linear time-invariant systems, linear and
circular block convolution, and fast Fourier transforms (FFTs), this article develops a …

Zero padding (ZP) of multicarrier transmissions has been proposed as an appealing
alternative to the traditional cyclic prefix (CP) orthogonal frequency-division multiplexing …

A companding technique is proposed to reduce the peak-to-average-power ratio of the
orthogonal frequency division multiplexing (OFDM) signal in this paper. The probability …

Channel estimation for mobile OFDM systems requires transmission of pilot tones. This
paper addresses the important issue of selecting these pilot tones, so as to achieve a good …

Multicarrier Modulation with Low PAR: Applications to DSL and Wireless provides the first
comprehensive formulation of the PAR problem for multicarrier modulation and proposes …
