Description:
We consider the multigenerator system{EmblTnalφl,m,n∈ℤ,l=0,…,r-1}forφ0,…,φr-1∈L2(?)anda0,b0,…,ar-1,br-1〉0, where the parametersb0,…,br-1〉0are not necessary the same. With the help of frame theory, we provide some sufficient or necessary conditions for the system to be a frame forL2(?). Moreover, we present some characterizations for this system to be a Parseval frame.
