Probably the first paper on multiple measurement vector (MMV) model

I uploaded the workshop paper by Prof. B.D.Rao and Prof. K.Kreutz-Delgado, which was presented in the 8th IEEE Digital Signal Processing Workshop, Bryce Canyon, UT, 1998. The workshop paper can be downloaded here.

Probably this is the first paper on the multiple measurement vector (MMV) model. As you can see, the MMV versions of FOCUSS, Matching Pursuit, Order Recursive Matching Pursuit, and Modified Matching Pursuit were all presented in this paper. These contents were fully discussed and extended in their journal paper under the same title (Sparse solutions to linear inverse problems with multiple measurement vectors). But unfortunately, the journal paper was published seven years later!!!
