Full Spark Frames

Alexeev, Boris, Cahill, Jameson, Mixon, Dustin G.

Understand

Finite frame theory has a number of real-world applications.

  • In applications like sparse signal processing, data transmission with robustness to erasures, and reconstruction without phase, there is a pressing need for deterministic constructions of frames with the following property: every size-M subcollection of the M-dimensional frame elements is a spanning set.
  • Such frames are called full spark frames, and this paper provides new constructions using the discrete Fourier transform.
  • Later, we prove that full spark Parseval frames are dense in the entire set of Parseval frames, meaning full spark frames are abundant, even if one imposes an additional tightness constraint.
