J-Shield is a robust filter on Javad GNSS antennas that blocks out-of-band interference (Figure 1). In particular, J-Shield blocks signals that are near the GNSS bands, including the proposed Ligado ...

The article presents an overlapping covert communication scheme based on the dynamic adjustment of the spread spectrum factor within a predefined range under a chaotic multi-tone framework, aiming to ...

Interference filters are frequently employed in transmissive configurations where the light passes through the filter to produce a specific effect (band-pass, long-pass, short-pass, among others).
