Superframes are vector-valued versions of frames which provide a tool
for sending several signals into a single channel (Multiplexing). They
have a rich mathematical structure which has been thoroughly
investigated in the last decade.
Recent advances in time-frequency analysis allow the use of superframes
to solve problems in complex analysis that were previously
out-of-reach, while estimating the lattice density of certain Gabor and
wavelet frames and superframes, as well as of Riesz and super-Riesz
