Abstract-- We design a novel class of space-time codes,
called linear diversity-embedding space-time block codes
(LDE-STBC) where a high-rate STBC is linearly superim-
posed on a high-diversity STBC without requiring channel
knowledge at the transmitter. In applying this scheme
to multimedia wireless communications, each traffic type
constitutes a transmission layer that operates at a suitable
rate-diversity tradeoff point according to its quality-of-
service requirements. This, in turn, provides an unequal-
error-protection (UEP) capability to the different infor-
mation traffic types and allows a form of wireless com-
munications where the high-rate STBC opportunistically
takes advantage of good channel realizations while the
embedded high-diversity STBC ensures that at least part
of the information is decoded reliably.
We investigate transceiver design issues specific to LDE-
STBC including reduced-complexity coherent decoding
