Video streaming performance on wireless networks is choppy. The culprit is the unpredictable wireless medium, whose fluctuations results in fluctuating throughput and bit errors. Current video codecsâ€¦ (More)

A method intended to characterize enclosed computational electromagnetic domains in terms of interaction and response of a defined set of surface excitations is described. The finite-element methodâ€¦ (More)

We study the problem of interpolating all values of a discrete signal f of length N when d <; N values are known, especially in the case when the Fourier transform of the signal is zero outside someâ€¦ (More)

Consider a unitary (up to scaling) submatrix of the Fourier matrix with rows indexed by <tex>$\mathcal{I}$</tex> and columns indexed by <tex>$\mathcal{J}$</tex>. From the column index setâ€¦ (More)

We study the problem of finding unitary submatrices of the discrete Fourier transform matrix. This problem is related to a diverse set of questions on idempotents on ZN , tiling ZN , differenceâ€¦ (More)
