Approximating Sampled Sinusoids and Multiband Signals Using Multiband Modulated DPSS Dictionaries
Many signal processing problems—such as analysis, compression, denoising, and reconstruction—can be facilitated by expressing the signal as a linear combination of atoms from a well-chosen dictionary. In this paper, we study possible dictionaries for representing the discrete vector one obtains when collecting a finite set of uniform samples from a multiband analog signal. By analyzing the spec...
متن کاملOptimized amplitude modulated multiband RF pulse design
PURPOSE Multiband pulses are characterized by highly temporally modulated waveforms. Rapid phase or frequency modulation can be extremely demanding on the performance of radiofrequency (RF) pulse generation, which can lead to errors that can be avoided if pulses are restricted to amplitude modulation (AM) only. In this work, three existing multiband pulse design techniques are modified to produ...
متن کاملParallel Imaging with RASER using Multiband Frequency-modulated Excitation Pulses
Introduction: The recently described RASER sequence is a conceptual novelty in MR imaging [1]. Based on frequency-swept excitation, and timeencoding, RASER is a rapid, pure T2-weighted scheme without signal voids, ghosting and distortion artifacts present in conventional echo-planar imaging (EPI). These properties render it attractive for functional imaging (fMRI). However, in the previous impl...
متن کاملMultirate asynchronous sampling of sparse multiband signals.
Because optical systems have a huge bandwidth and are capable of generating low-noise short pulses, they are ideal for undersampling multiband signals that are located within a very broad frequency range. We propose a new scheme for reconstructing multiband signals that occupy a small part of a given broad frequency range under the constraint of a small number of sampling channels. The scheme, ...
متن کاملCompressive Sensing of Analog Signals Using Discrete Prolate Spheroidal Sequences
Compressive sensing (CS) has recently emerged as a framework for efficiently capturing signals that are sparse or compressible in an appropriate basis. While often motivated as an alternative to Nyquist-rate sampling, there remains a gap between the discrete, finite-dimensional CS framework and the problem of acquiring a continuous-time signal. In this paper, we attempt to bridge this gap by ex...
