Interfeference Alignment on MIMO X channel with Synergistic CSIT


The achievable degree of freedom (DoF) boosting has been
demonstrated on a single-input single-output (SISO) X channel
by using outdated and instantaneous channel state information
at transmitter (CSIT) synergistically, in contrast to
that of using completely outdated CSIT. However, the means
by which the DoF gain can be obtained in a multiple-input
multiple-output (MIMO) system remains unclear. This paper
proposes an interference alignment scheme with synergistic
CSIT for MIMO X channel. We show that the achievable

A JOINT DESIGN APPROACH FOR SPECTRUM SHARING BETWEEN RADAR AND COMMUNICATION SYSTEMS


Diagram for Coexisting Radar and Communication Systems

A joint design approach is proposed for spectrum sharing between MIMO radar and MIMO communication systems. Radar transmit precoding and adaptive communication transmission are adopted, and are jointly designed to maximize signal-to-interference-plus-noise ratio (SINR) at the radar receiver subject to the communication system meeting certain rate and power constraints. We start with the design of a system in which knowledge of the target information is used. Such design can be used to benchmark the performance of schemes that do not use target information.

Radar Precoding for Spectrum Sharing Between Matrix Completion Based MIMO Radars and A MIMO Communication System


The paper investigates a new framework for spectrum sharing between a MIMO-MC radar (MIMO radar using matrix completion) and a MIMO communication system, based on radar transmit precoding. The radar transmit precoder is jointly designed with the communication codewords so that the SINR at the radar receiver is maximized while meeting certain rate and power constraints at the communication system. By shaping the transmit beam, the proposed approach results in enhanced SINR at the receive antennas.
