Paper Abstract
We propose a design procedure for the real, equal-norm, lapped tight frame transforms (LTFTs). These transforms
have been recently proposed as both a redundant counterpart to lapped orthogonal transforms and an
infinite-dimensional counterpart to harmonic tight frames. In addition, LTFTs can be efficiently implemented
with filter banks. The procedure consists of two steps. First, we construct new lapped orthogonal transforms
designed from submatrices of the DFT matrix. Then we specify the seeding procedure that yields real equal-norm
LTFTs. Among them we identify the subclass of maximally robust to erasures LTFTs.
