BeamformingVirtual phased arraydeconvolution algorithmBeamforming techniques using phased microphone arrays are one of the most common tools for localizing and quantifying noise sources. However, the use of such devices can result in a series of well-known disadvantages regarding, for instance, their ...
Antennas that can operate across multiple communication standards have remained a challenge. To address these limitations, we propose a Field-Programmable Radio Frequency Surface (FPRFS), which is based on manipulating current flow on its surface to achi
In this paper, a robust STAP beamforming algorithm is proposed for GNSS receivers to maintain beamformer performance in high dynamic environment. On the one hand, due to the fast motion of the GNSS receiver, the DOA estimates for the desired GNSS signals are not accurate, which will result ...
To keep the overhead low, Janus spreads the checkpoints using the greedy Algorithm 1. Initially, Janus adds checkpoints right after the invocation of helper functions marked by the vendors as long lasting and thus potentially unsafe, if used often (line 2). Next, it uses the static analysis...
These large arrays at UE are particularly suitable for UL-dominant scenarios. Our preliminary field trial (also under 300 to 400 m ISD) shows that a 16–32 antenna array is required at UE to guarantee a targeted UL data rate of 30 Mbps. With obvious benefits from using large arrays at ...
This method shows better performance than the Bartlett beamformer as it can distinguish between angles with small separation, and it also suppresses the side lobes levels. One drawback of the Capon method is the expensive calculation for the inverse matrix for large antenna arrays [139]. The Cap...
An iterative synthesis technique based on a successive fast Fourier transform (SFFT) is proposed in [37] to obtain a low SLL for large planar antenna array. It is shown that this algorithm is applicable to a planar array with one-thousand elements. Although the simplicity of the algorithm ...

For a class of convex optimization problems, a coordinate descent algorithm was presented in Friedman et al. (2007), which is a one-at-a-time coordinate-wise descent algorithm, and can be generalized to solve the 2D fused Lasso or even higher dimensional cases. To handle large-scale fused ...
large-diameter (>20 mm) beam incident on the FP ultrasound sensor head, the acoustically sensitive element of which is a thin film polymer FP interferometer (FPI). Since the FPI is transparent in the 560–1,300 nm wavelength range (Supplementary Fig.1), the excitation beam passes ...
