This paper aims to investigate sufficient conditions for the recovery of sparse signals via the orthogonal matching pursuit (OMP) algorithm. In the noiseless case, we present a novel sufficient ...

Representation of signals: Fourier analysis, fast Fourier transforms, orthogonal expansions. Transformation of signals: linear filters, modulation; band-limited signals; sampling; uncertainty ...

MicroSD cards are the smallest memory cards commercially available and are used in a host of devices such as mobile phones, tablet PCs, digital audio players, digital cameras and other electronic ...

As more high-speed amplifier applications deal with communication systems, wired or wireless, a brief introduction and overview of orthogonal frequency division multiplex (OFDM) is necessary. With a ...

Orthogonal frequency division multiplexing (OFDM) has become attractive for many current and emerging commercial applications because it provides a combination of data throughput, scalability, and ...

Wavelets provide new capabilities for analyzing real-time signals. This introductory article provides an overview and presents the basic mechanisms involved in wavelets. In many signal processing ...
