This paper investigates the characteristics of the shadowed fading observed in off-body communications channels at 5.8 GHz. This is realized with the aid of the κ–μ/gamma composite fading model, which assumes that the transmitted signal undergoes κ–μ fading, which is subject to multiplicative shadowing. Based on this, the total power of the multipath components, including both the dominant and ...

Unintentional attacks on watermarking schemes lead to degrade the watermarking channel, while intentional attacks try to access the watermarking channel. Therefore, watermarking schemes should be robust and secure against unintentional and intentional attacks respectively. Usual security attack on watermarking schemes is the Known Message Attack (KMA). Most popular watermarking scheme with stru...

Comprehensive knowledge of the channel and accurate channel models are essential in the optimized system design. In the Wireless Body Area Network (WBAN) applications, use of Ultra Wideband (UWB) transmission as well as close presence of human body, bring their own major challenges in the channel modeling. Several channel models have been proposed and numerous channel measurement campaigns have...

Coherent states of the quantum electromagnetic field, description ideal laser light, are prime candidates as information carriers for optical communications. A large body literature exists on their quantum-limited estimation and discrimination. However, very little is known about practical realizations receivers unambiguous state discrimination (USD) coherent states. Here we fill this gap outli...

Medical applications have driven many areas of engineering to optimize diagnostic capabilities and convenience. In the near future, wireless body area networks (WBANs) are expected widespread impact in medicine. To achieve this impact, however, significant advances research needed cope with changes human body’s state, which make coherent communications difficult or even impossible. paper, we co...

The space-air-ground integrated network (SAGIN) has drawn increasing attention for its benefits, such as wide coverage, high throughput 5G and 6G communications. As one of the links, space-air communications between multiple unmanned aerial vehicles (UAVs) Ka-band orbiting low earth orbit (LEO) satellites face a crucial challenge in tracking 3D dynamic channel information. This paper exploits s...

The performance of dual heard pulse interval modulation (DH-PIM) employing least mean square error equaliser (LMSE) in diffuse infrared indoor environment is presented. The work is based on the ceiling bounce channel model and the Monte Carlos simulation. A 3-tap LMSE equaliser is used and results are compared with unequalised DH-PIM and with DH-PIM employing linear zero forcing equaliser (L-ZF...
