MITSE - MIMO Techniques for 3G System and Standard Evolution

Wireless System Development

Data rates as well as quality of service requirements for rich user experience in wireless communication services are continuously growing. More and more devices will be connected to the global ubiquitous information network. The last, and often also the furthest connection will essentially always be wireless. At the same time more and more applications require high data rates to provide multimedia services. This will require high capacity, improved coverage and flexibility from future wireless communication systems and networks. The data rate goals of evolving systems require vast improvements in all the layers of wireless networks and also new paradigms, like cross-layer design. One of the main capacity boosters at the physical layer is the use of multiple antennas in both/either the transmitter and/or the receiver.

Towards Utilization of Multi-Antenna Techniques

The use of multiple antennas in both the transmitter and the receiver results in a so-called multiple-input-multiple-output (MIMO) radio channel as opposed to the conventional single-input-single-output (SISO) radio channel. Obvious compromises include single-input-multiple-output (SIMO) and multiple-input-single-output (MISO) channels. Application of multiple antennas provides the potential to increase the capacity of the wireless channel significantly. Multiple antennas can be utilized within a single link in the form of either diversity, beam-forming or spatial multiplexing (often called layering). A multiuser system-level approach enables even more options due to multiuser diversity and opportunistic scheduling.

MITSE Project

MITSE is a B3G cellular communication system research project. The scope and content of the project covers future development and evolution of 3G cellular communication systems known as 3G Long-Term Evolution and IMT-A. The main emphasis is on MIMO transmission schemes and receiver algorithms and architectures as well as computation solutions needed by them in multiuser OFDM(A) and SC-FDMA systems.

Impact

MITSE-project has produced novel adaptive transmission schemes and MIMO receiver algorithms and their implementation solutions. Algorithms can be utilized in MIMO-OFDM systems such as LTE/LTE-A and Mobile WiMAX.
