Call for Papers
Diversity is a powerful technique to mitigate channel fading and to improve
robustness to cochannel interference in a wireless network. Space-time wireless
systems traditionally use multiple colocated antennas at the transmitter and
receiver along with appropriate signal design (also known as space-time coding)
to realize spatial diversity in the link. Typically this diversity can augment
any frequency and time diversity available to the receiver. Multiple antennas
also offer the ability to use spatial multiplexing to dramatically increase the
data rate.
A recent development in this area aims at dispensing with the need for
colocated antennas. Popularly known as the cooperative diversity
technique, this uses the antennas at multiple user terminals in a network in the
form of a virtual antenna array to realize spatial diversity in a distributed
fashion. Such techniques create new challenges in the design of wireless
systems.
The purpose of this call for papers is to address some of these challenges
such as new protocols for cooperative diversity, cross-layer design, cooperative
multiplexing, space-time coding for distributed antennas, cooperative channel
estimation and equalization, selecting the right users for participating in a
cooperative network, modulation specific issues like OFDMA and CDMA, and
distributed space-time processing for sensor networks.
Papers on the following and related topics are solicited for this special
issue:
- New protocols for cooperative diversity systems
- Cross-layer protocol design
- Signal design for distributed space-time systems
- Cooperative channel estimation and equalization
- Cooperative MIMO systems
- Distributed space-time processing for sensor networks
- Power allocation in distributed space-time systems
- Fast algorithms and efficient architectures for virtual MIMO receivers
- Energy efficient relay network architectures
