Abstract
In this article, we introduce Fa-C-D controlled frame and characterize Fa-C-D dual of Fa-C-D controlled frames in L^2(R^+) and addresses Fa-C-D controlled frames in the setting of subspaces of L^2(R^+). We also establish the connection between Fa-C-D controlled frames and C-D controlled frames and the connection between subspaces with Fa-C-D controlled frames and orthogonal projections.
