In this paper, minimum redundancy multiple-input multiple-output (MR-MIMO) arrays - a class of thinned antenna arrays - are discussed. The concepts of MR-MIMO array design and almost difference sets (ADSs) are introduced, and an analytical method based on ADSs is proposed for MR-MIMO array designs. This method can quickly determine the locations of MR-MIMO arrays and require little computational cost...
The multi-antenna configurations used in MIMO (multi-input multi-output) system can greatly improve the transmission reliability and channel capacity. Antenna selection technique can reduce the implementation complexity and hardware cost while maintaining the advantages of MIMO system. Aiming at selecting the optimal antenna subset quickly in the changeable channel environment, a binary particle swarm...
In this paper, the antenna array design problem in minimum redundancy MIMO radars is addressed, which seeks to maximize the virtual array aperture for a given number of transmitting and receiving (Tx/Rx) elements. A hybrid optimization method combining cyclic difference sets (CDSs) with simulated annealing (SA) is proposed for the optimal design of Tx/Rx antenna arrays. Numerical results are also...
