“…For example, the loss of data packets during transmission through the internet from satellites can be viewed as a nonuniform sampling problem. The nonuniform sampling problem has been studied in recent years [7,8,12,16,17,20,22,24]. The problems of uniform and nonuniform sampling and reconstruction also have been extended to more general shift-invariant spaces of the form…”

Vector sampling expansions in shift invariant subspaces

“…Recently, multi-input multi-output (MIMO) sampling scheme which is motivated by applications in multi-channel deconvolution and multi-source separation has been investigated in many aspects (see [22,30,31] and references therein). Some example applications include multi-user or multi-access wireless communications and space-time coding with antenna arrays or telephone digital subscriber loops [20], multi-sensor biomedical signals [39], and multi-channel image restoration [14].…”

Least Sampling Density from High Order Sampling

“…But the determinate of the matrix of the coefficients doesn't vanish, this system is sovable uniquely. [4] …”
