This repository contains the implementation of a Frequency-Hopping Spread Spectrum (FHSS) communication system developed as part of the EE430 Digital Signal Processing course at METU. The project ...

Because the chip rate is higher than the symbol rate, the spectrum of the modulated signal is extended; 2) Frequency hop-ping spread spectrum, that is, carrier frequency hopping in a symbol time, so ...

We analyze the probability of no uplink collision under two DtS-IoT settings: 1) unconfirmed ALOHA over a single channel, e.g., long-range wide-area network (LoRaWAN) class A with long-range chirp ...

These operate in the same unlicensed 2.4 GHz ISM (Industrial, Scientific and Medical) radio band as does Bluetooth. To improve performance in these environments, a technique known as Adaptive ...

Frequency hopping sequences (FHS) are crucial in wireless communication systems, particularly in environments where interference is prevalent. These sequences allow for the rapid switching of ...

And due to the fact that most nodes will have multiple paths for the data, there should be an extremely low probability of missing data. The use of Frequency Hopping Spread Spectrum (FHSS) techniques ...

To reduce the required power cost of strong signal, a new design method for anti-interception waveform is proposed, which combines the strong signal masking technology with the variable parameter ...

The U.S. Air Force is arming its fleet of F-15 Eagle fighter jets with a new aircraft targeting sensor engineered to function in a challenged, or “radar-denied” environment. The Legion ...

Szenes legacy is such that Agent Peggy Carter in the Marvel Cinematic Universe’s Agent draws inspiration from real-life ...

The most reliable way to prevent hackers from spying on your nursery is to use of the best non-Wi-Fi baby monitors. Here are ...

They are the result of studies undertaken by Radiocommunication Study Groups on: the use of a vast range of wireless services, including popular new mobile communication technologies: the management ...

On Shanghai's Bund, it's a relief to see the waterfront thronged with people. Last time I stood here – back in February 2020, in the first days of the Covid-19 pandemic – I was entirely alone.
