A frame synchronization algorithm based on delay-Doppler domain was proposed for orthogonal time frequency and space (OTFS) modulation systems with a single pilot structure. The signal sparsity and the relative position change of the pilot in the del

We consider a Low Earth Orbit (LEO) satellite hosting a 5G base station transmitting to a handheld device in L-band or S-band. This link is critical because it is characterized by a very low Signal-to-Noise Ratio and significant Residual Frequency Of

In this paper, a deep-learning-based frame synchronization blind recognition algorithm is proposed to improve the detection performance in non-cooperative communication systems. Current methods face challenges in accurately detecting frames under hig

Display field communication (DFC) is a spectral domain-based, unobtrusive display-to-camera (D2C) communication method in which a commercially available digital display serves as the transmitter and an off-the-shelf camera serves as the receiver. The

The efficient and cost-effective suppression of atmospheric turbulence effects in free-space optical (FSO) communication poses a significant challenge. To address this challenge, a carrier frequency offset estimation (FOE) scheme based on frame-synch
