Physical Layer: Implement Encryption or Jamming-Resistant Modulation Technique

-
Image
Data Security at the Physical Layer: A Case Study To study the impact of jamming on secure communication, I will explore the following techniques: Basic Encryption: Simple XOR encryption was used to demonstrate the concept of physical layer security. Jamming Simulation: A specific frequency band was targeted for jamming, mimicking real-world interference scenarios. Frequency Hopping: To counteract jamming, the transmission frequency was dynamically changed. Advanced Encryption: AES-128 encryption was employed to enhance the security of the transmitted data. Modulation: QAM modulation was used to map digital data onto analog signals for transmission. Layered Encryption: A layered approach combining symmetric and asymmetric encryption was investigated to provide robust security. Adaptive Modulation: The modulation scheme was dynamically adjusted to optimize performance based on channel conditions. Error Correction: Hamming codes were used to introduce redundancy into the ...

  Hello everyone! 👋Welcome to " Bits and Bytes of Wireless ". 🎯 Today's Topic: Exploring the 5G Technology Core Architecture. Topics Covered 🌀 5G Core Network Functions 📡 5G Core Network Protocols 🎛️ 5G Network Slicing (NS) ☁️ 5G Core Network Deployment and Operations 5G System: High Level This is the big picture of how 5G networks function to provide seamless connectivity and advanced services. 1. Key Components of the 5G System: UE (User Equipment): The end-user device, such as smartphones, IoT devices, or industrial equipment, connects to the 5G network. It communicates with the network through the radio part of 5G, called 5G NR (New Radio). NG-RAN (Next-Generation Radio Access Network): The gNB (5G Base Station) is a critical part of the NG-RAN and is responsible for wireless communication between the UE and the network. The New Radio (NR) supports features like higher frequencies, wider bandwidths, and advanced technologies like beamforming and massive MIMO. 5G...

Interactive Modulation Tutorial with Examples Interactive Modulation Tutorial 1.3.1 Amplitude Modulation (AM) In Amplitude Modulation, the carrier's amplitude changes with the message signal. Formula: $$ s(t) = [1 + m(t)] \cos(2\pi f_c t) $$ Key Concept: Modulation Index The modulation index (m) determines how much the carrier amplitude varies: $$ m = \frac{A_{max} - A_{min}}{A_{max} + A_{min}} $$ Must be ≤ 1 to avoid distortion (overmodulation). Carrier Frequency (Hz) 10 Hz Message Frequency (Hz) 1 Hz Modulation Index 0.5 This plot shows the amplitude modulated signal with the message signal superimposed. Example Calculation: Suppose \( m(t) = 0.5 \sin(2\pi \times 1 t) \) (1 Hz message), and ...
