Minimum redundancy MIMO array design using cyclic permutation of perfect distance (CPPD)

In this paper, minimum redundancy multiple-input multiple-output (MR-MIMO) arrays - a class of thinned antenna arrays - are discussed. The concepts of minimum redundancy array (MRA) and cyclic permutation of perfect distance (CPPD) are introduced, and an analytical method based on CPPD is proposed for MR-MIMO array designs. This method can quickly determine the locations of MR-MIMO arrays and require little computational cost. Numerical examples are presented, showing the advantages of the proposed method in spatial resolution performance and computational efficiency.
