Diversity in Cooperative Networks. Edition No. 1
VDM Publishing House, Nov 2008, Pages: 180
Recently, there has been much interest in modulation
techniques to achieve transmit
diversity motivated by the increased capacity of
multiple-input multiple- output (MIMO)
channels. It is affordable to equip base stations
with more than one antenna, but it is
difficult to equip the small mobile units with more
than one antenna. In such a case,
transmit diversity can only be achieved through user
cooperation leading to what is known
as cooperative diversity. Cooperation provides a new
dimension over which higher diversity
orders can be achieved.
In this thesis, we consider the design of protocols
that allow several terminals to cooperate
via forwarding each others' data, which can increase
the system reliability by achieving
spatial cooperative diversity. We consider the
problem of how to achieve and where to
exploit diversity in cooperative networks?
