The repeated melting and solidification cycles in the laser powder bed fusion (L-PBF) process lead to significant thermal gradients, resulting in notable distortion in the as-built part. Distortion compensation methods, which pre-deform the part desi

Peak limiter-based techniques such as peak canceler (PC) have been investigated as simple solutions for reducing the peak-to-average power ratio (PAPR) in massive multi-input multi-output (mMIMO) orthogonal frequency division multiplexing (OFDM) syst

To improve the robustness of vortex beam transmission and detection in the face of atmospheric turbulence and to guarantee accurate recognition of orbital angular momentum (OAM), we present an end-to-end dynamic compensation technique for vortex beam

Membrane reflectarray antennas with flexible support structures realize low weight and low stowage volume. However, deformation of the reflectarray membrane generally degrades antenna gain. We propose electrical misalignment compensation for 5.8-GHz-

Consumer-level UAVs are often employed for surveillance, especially in urban areas. Within this context, human recognition via estimation of biometric traits, like body height, is of pivotal relevance. Previous studies confirmed that the pinhole mode
