CAWE-ACNN Algorithm for Coprime Sensor Array Adaptive Beamforming. [PDF]
Sensors (Basel)This paper presents a robust adaptive beamforming algorithm based on an attention convolutional neural network (ACNN) for coprime sensor arrays, named the CAWE-ACNN algorithm. In the proposed algorithm, via a spatial and channel attention unit, an ACNN model is constructed to enhance the features contributing to beamforming weight vector estimation and

Passive beamforming with coprime arrays
IET Radar, Sonar & Navigation, 2017 Coprime arrays have been recently proposed as effective sparse configurations suitable for radar beamforming and angle‐of‐arrival estimation applications. In this study, a new approach for passive beamforming using coprime arrays is presented. In particular, a new detection strategy is proposed, which outperforms the coprime processors presently ...

Results and conjectures on simultaneous core partitions [PDF]
, 2013 An n-core partition is an integer partition whose Young diagram contains no hook lengths equal to n. We consider partitions that are simultaneously a-core and b-core for two relatively prime integers a and b.

Enhance Degrees of Freedom for Coprime Array Using OptSpace Algorithm
IEEE Access, 2019 Coprime arrays, consisting of two subarrays with a co-prime number of physical sensors, can effectively resolve the direction-of-arrival (DOA) estimation when the number of sources exceeds the sensors. However, the conventional coprime array direction of

Implementing Shor's algorithm on Josephson Charge Qubits [PDF]
, 2004 We investigate the physical implementation of Shor's factorization algorithm on a Josephson charge qubit register. While we pursue a universal method to factor a composite integer of any size, the scheme is demonstrated for the number 21.

DOA estimation of underwater acoustic co-frequency sources for the coprime vector sensor array
Frontiers in Marine Science, 2023 A coprime array with fewer sensors can achieve the same resolution as a uniform linear array. However, when detecting co-frequency targets, there can be prominent false alarms due to overlaps between the main and grating lobes of subarrays.
