Splitting a signal into N filtered channels subsampled by N is an important problem in digital signal processing. A fundamental property of such a system is that the original signal can be perfectly recovered from the subsampled channels. It is shown that ...
Frequency-modulated chirp pulses, for exciting multiple-quantum coherences over large bandwidths, can be considered as an alternative to composite pulses to combat the effects of large offsets and tilted effective fields. Refocusing of the phase dispersion ...

In this paper, we describe linear turbo equalizers (TEQ) and investigate their practical application to underwater acoustic communications. Owing to the ability to achieve a good performance-complexity trade-off, linear TEQ is a good candidate for long rev ...
We propose a stochastic Forward-Douglas-Rachford Splitting framework for finding a zero point of the sum of three maximally monotone operators, one of which is cocoercive, in a real separable Hilbert space. We characterize the rate of convergence in expect ...
It is shown by simulation and expt. that frequency-modulated "chirp" pulses are very effective for exciting multiple-quantum coherences over large bandwidths. Chirp pulses can be considered as an alternative to composite pulses to combat the effects of l ...
We study an iterative, locally quadratically convergent algorithm for solving Toeplitz systems of equations from [R. P. Brent, F. G. Gustavson and D. Y. Y. Yun. ''Fast solution of Toeplitz systems of equations and computation of Pade approximations'', J. A ...
The potential for identifying aircraft using one or more radar range profiles, in conjunction with a correlator, is investigated. Two types of filters are described which maximize the expected value of certain correlation peaks. The effectiveness of one ty ...
In NMR pulse experiments transverse magnetization is excited by irradiating the nuclear spin system with a two pulse sequence of a first RF chirp pulse and a second RF chirp pulse, generated after a defocusing time interval tau . The pulse duration of the ...
In this study, we report that intercalation of tin into montmorillonite clay (Sn‐MMT) boosts catalytic activity for the synthesis of polyoxymethylene dimethyl ethers, a promising diesel fuel additive. This increase in activity is attributed to the formatio ...
