Extension of nested arrays with the fourth-order difference co-array enhancement [PDF]
2016 IEEE International Conference on Acoustics, Speech and Signal Processing (ICASSP), 2016 To reach a higher number of degrees of freedom by exploiting the fourth-order difference co-array concept, an effective structure extension based on two-level nested arrays is proposed. It increases the number of consecutive lags in the fourth-order difference coarray, and a virtual uniform linear array (ULA) with more sensors and a larger aperture is ...

A New Nested Array Configuration With Increased Degrees of Freedom
IEEE Access, 2018 In this paper, a new linear array configuration based on the concept of two-level nested array is proposed. Specifically, the proposed array configuration consists of two uniform linear arrays (ULAs) plus a separate sensor with appropriate spacing apart.

IEEE Access, 2020 In practice, there are many circular and non-circular signals due to multipath propagation and various modulations. Conventional direction-of-arrival (DOA) estimation in a mixture of circular and non-circular signals cannot distinguish two kind of ...

, 2016 Orthogonal Arrays allow us to test various levels of each factor and balance the different factors so that we can estimate interactions as well as first order effects. There is a trade-off between how well we can sample different levels of each factor and how many interactions we are able to estimate.

Evaluating Spatial Resolution and Channel Capacity of Sparse Cylindrical Arrays for Massive MIMO
IEEE Access, 2017 How to design antenna arrays plays an important role in wireless communications, especially when there are hundreds of antennas. In massive multiple-input and multiple-output (MIMO), if the number of antennas and RF chains are increasing, the channel ...

Statistical Nested Sensor Array Signal Processing
, 2015 Source number detection and direction-of-arrival (DOA) estimation are two major applications of sensor arrays. Both applications are often confined to the use of uniform linear arrays (ULAs), which is expensive and difficult to yield wide aperture ...

Underdetermined direction-of-arrival estimation using super nested array
The Journal of Engineering, 2019 Among various sparse-arrays, super nested array (SNA) is found to be more attractive because it can achieve large degrees-of-freedom (DOFs) and alleviate the mutual coupling. This article address the problem of direction-of-arrival (DOA) estimation under
