Recently, sparse arrays such as nested array and coprime have attracted much attention in the field of signal processing. In this letter, we develop a symmetric (SCA) whose sensor locations satisfy nesting property, so it can be used dense subarray array. Based on observation, propose new named array, which achieve same number uniform degrees freedom (uDOFs) prototype while mutual coupling effect is at level arrays. Moreover, an improved (ICNA) proposed by rearranging some sensors SCA to...
Recently, direction of arrival (DOA) estimation for non-circular (NC) sources has attracted great attention in array signal processing since NC signals can provide more information to generate the virtual difference and sum (diff-sum) coarray. In this paper, we propose a generalized vectorized noncircular MUSIC (GVNCM) method, which solve underdetermined DOA problem when coarray are discontinuous. Based on GVNCM algorithm, an extended transformed nested strategy is proposed by splitting...
Recently, the concept of difference and sum coarray has attracted increasing interest in direction arrival estimation field because it can generate enhanced degrees freedom. In this paper, we propose an improved transformed nested array design strategy by relaxing constraints on dense subarray array. Then, three conditions are given for to ensure continuity coarray. Based strategy, develop a novel configuration named coprime (CTNA) whose is structure, closed-form expressions sensor positions...
The common and differential mode (CM/DM) method indicates that when the odd impedance of a dual-antenna system are same, two antennas achieve best isolation. In this paper, broadband MIMO antenna based CM/DM is proposed. By transforming magnetoelectric dipole (ME) prototype with feed into dual antenna, can be obtained. replacing electric folded adjusting parameters appropriately, bandwidth DM broadened. final achieves isolation more than 15dB in about 44% bands S11 less -8dB, gain band...
