LR-FHSS: Overview and Performance Analysis

Performance Analysis of DSSS and FHSS Techniques over AWGN Channel

With the ever-growing advancements in the field of technology, Digital communication systems are becoming increasingly attractive and flexible for a secure form of data communication. Spread Spectrum overcomes the severe levels of interference that are encountered in the transmission of the digital information and rely upon shift register codes. This paper is in accordance with the design of Sp...

DSSS vs. FHSS narrowband interference performance issues

D spread spectrum (DSSS) and frequency-hopping spread spectrum (FHSS) technologies have different physical mechanisms for rejecting narrowband interference. Because of these physical differences, they perform differently in the presence of the same levels of narrowband interference. This is an important case for successful operation in the ISM bands. After presenting the physical mechanisms by ...

Security Analysis of FHSS-type Drone Controller

Unmanned Aerial Vehicles (UAVs), or drones, have attracted a considerable amount of attentions due to their utility to civilian as well as military applications. However, the security issues involved in UAV technology have not been extensively discussed in the literature. As a first step toward analyzing these security issues, we investigate security in drone controllers, especially controllers...

Security Improvement by using Dual Coded FHSS (DC-FHSS)

In this paper a technique is offered for improving the security of data transmission. In today’s technical world the prime objective of wireless communication is to make the transmission not only clear, noise free and time efficient but also to make it well secure from unauthorized interceptors. Frequency hopping is a technique used for this purpose in which the random sequence is used to add w...
