Robust frequency-domain precoders

IEEE Communications Letters, 2001
This letter introduces a novel class of linear precoders which explicitly add algebraic redundancy in the frequency domain. A procedure for designing robust precoders of the above form for transmission through unknown channels is derived. Such precoders guard against the adverse effects of narrowband interference and frequency selective fading channels.

The frequency domain

2002
We are familiar with systems that are dynamic, that is, systems whose output signals vary with time. Examples are shown in Figure 14.1.

Frequency domain representations of surfaces

SMC'98 Conference Proceedings. 1998 IEEE International Conference on Systems, Man, and Cybernetics (Cat. No.98CH36218), 2002
We present "surface frequency" representations, which describe how Cartesian positions on a surface vary with the intrinsic position along the surface. These representations are constructed using optimized coordinate values, individual sample weights, and an iterative transform algorithm.

Texture Transfer in Frequency Domain

2011 Sixth International Conference on Image and Graphics, 2011
Texture transfer has been extensively studied in literature recently. Most of the techniques are either structural or statistical, with an emphasis on utilizing texture synthesis algorithms. In this paper we address texture transfer in an alternative way, that is, to extract texture information in frequency domain, and then apply it to the target image.

Frequency domain Nonlinear Optics

Nonlinear Optics, 2017
Frequency-domain Nonlinear Optics (FNO) merges the simplicity of linear optics with the power of nonlinear optics. Employing FNO, we demonstrate pulse shaping in the deep UV and amplification of two-cycle infrared pulses to 2.5 TW.

Frequency domain testing of ADCs

IEEE Design & Test of Computers, 1996
Aimed at design and test engineers making the transition from strictly digital devices to devices with both digital and analog content, this tutorial introduces frequency domain analysis for the testing of mixed-signal devices. The author describes dynamic testing of analog-to-digital converters using Fourier analysis, including coherent sampling ...

Analysis and Synthesis in the Frequency Domain

1997
This chapter begins with a brief discussion of the Nyquist stability criterion and recalling the important concepts of gain and phase margins. Next, the feedback specification for single-input single-output system is discussed, together with various representations of the unstructured uncertainty, robust performance, and robust stability.

Life in the Frequency-Phase Domain

2016
The concept of autopoiesis --- a living system as a network of processes that continuously produces the very components constituting that network --- has remained without a computable formalization since its introduction by Maturana and Varela in 1973.
