Efficient Space-Time Signalling Schemes. Edition No. 1
VDM Publishing House, Aug 2008, Pages: 196
This monograph presents efficient techniques for
communicating over wireless multiple-input multiple-
output (MIMO) frequency-flat block-fading channels.
For coherent systems, in which full channel state
information (CSI) is available at the receiver, but
not at the transmitter, it shows that linear
dispersion codes that are constructed from large
random unitary matrices achieve minimum mean square
error and minimum pairwise error probability.
Furthermore, these codes achieve maximum mutual
information between transmitted and received signals.
For non-coherent MIMO systems, in which no CSI is
available at the transmitter or the receiver, this
monograph addresses the design of Grassmannian
constellations that enable the high signal-to-noise
ratio non-coherent ergodic capacity to be
approached. The design of these consetllations is
based on a perturbation analysis that shows the
appropriateness of using the chordal Frobenius norm
as a design metric. Finally, the monograph presents
a non-coherent detector whose performance is
comparable to that of the maximum likelihood
detector, but it requires significantly less
computational effort.
