1. 1. Time-based Key for Coverless Audio Steganography: A Proposed Behavioral Method to Increase Capacity

   University essay from Blekinge Tekniska Högskola/Institutionen för datavetenskap

   Author : John Alanko Öberg; Carl Svensson; [2023]
   Keywords : Coverless audio steganography; information hiding; covert communication; effective capacity; behavioral; Täcklös ljudsteganografi; informationsdöljning; hemlig kommunikation; effektiv kapacitet; beteendemässig;

   Abstract : Background. Coverless steganography is a relatively unexplored area of steganography where the message is not embedded into a cover media. Instead the message is derived from one or several properties already existing in the carrier media. This renders steganalysis methods used for traditional steganography useless. READ MORE

3. 2. Examining the Effects of AWGN Jamming on a Tactical Data Link Communication System

   University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

   Author : Noor Schroen; [2023]
   Keywords : Tactical Data Links; VOACAP; HF; AWGN; Jamming; Tactical Data Links; VOACAP; HF; AWGN; Jamming; Tactical Data Links; VOACAP; HF; AWGN; Jamming;

   Abstract : This master thesis investigates the jamming of Tactical Data Links (TDLs). The goal is to make a model that is capable of giving an overview of a communication system under jamming conditions, offering the user a suggestion for the best coding scheme and modulation to use in any given situation.

4. 3. Performance Analysis of STTC-Based MIMO Under Cognitive RadioScenarios

   University essay from Blekinge Tekniska Högskola/Institutionen för datavetenskap

   Author : Sanjana Kankantee; Sai Praneeth Reddy Ganta; [2023]
   Keywords : Space-time trellis coding; MIMO; Cognitive radio; Performance; Bit error rate; Diversity; AWGN; Rayleigh fading; Detection; Spectrum.;

   Abstract : This thesis presents a comprehensive investigation into improving wireless transmission rates and reliability through the implementation of Space Time Trellis Codes(STTC). The study focuses on enhancing the coding gain, diversity gain, and flexible transmission capabilities, which are crucial for Error-Correcting Codes (ECC)in wireless communications. READ MORE

5. 4. Autonomous Landing of an Unmanned Aerial Vehicle on an Unmanned Ground Vehicle using Model Predictive Control

   University essay from Linköpings universitet/Institutionen för systemteknik

   Author : Emil Boström; Erik Börjesson; [2022]
   Keywords : Model predictive control; MPC; Unmanned aerial vehicle; UAV; Unmanned ground vehicle; UGV; Path planning; Vehicle dynamics; Autonomous systems; Autonomous landing; Quadcopter; Gazebo; ROS;

   Abstract : The research on autonomous vehicles, and more specifically cooperation between autonomous vehicles, has become a prominent research field during the last cou- ple of decades. One example is the combination of an unmanned aerial vehicle (UAV) together with an unmanned ground vehicle (UGV). READ MORE

6. 5. Importance Sampling in Wireless Communication Systems with Ultra-Low Error Rates

   University essay from Lunds universitet/Institutionen för elektro- och informationsteknik

   Author : Bharat Maheshwari; Yewen Zhou; [2022]
   Keywords : error region; Monte Carlo; importance sampling; rejection sampling; Kullback-Leibler divergence.; Technology and Engineering;

   Abstract : Simulation mimics the behaviour of real world processes or the system over time. It helps us to understand the impact of modification and the effect of introducing various interventions to a system. READ MORE
