• This research focuses on wireless communications
  with the aim of increasing transmission rates for
  multi-hop wireless networks, as well as reducing
  the cost and extending the service life of the
  individual network nodes. It builds on and
  expands the researchers previous work on the
  subject of space-time diversity in wireless
  communications. It extends towards cooperative
  diversity methods in CDMA ad-hoc networks with
  RAKE receivers and MIMO systems.

• Our work is a novel framework of cooperative
  multi-input-multi-output (MIMO) diversity schemes
  in CDMA wireless multi-hop networks, where none
  of the nodes have multiple antennas. Using
  clusters of network nodes to relay wholly or
  partially correlated information to its
  destination both to increase effective rates and
  extend the nodes' service lives are concepts
  which are not fully developed. These proposed
  systems can truly achieve MIMO-type performance
  in a distributed way due to the use of coarse
  transmitter synchronization schemes complemented
  by RAKE receivers.

• A form of combining improved signal to noise
  ratio as well as security for a multi-hop
  wireless network is to use time-reversal
  techniques and antenna arrays at both
  transmitters and receivers. The work develops a
  theoretical foundation for this subject.

• This work takes advantage of temporal and
  spatial focusing properties of time-reversal, so
  as to provide an independent data stream to each
  antenna element.
