1. 1. Automation of ultrasonic Time-of-Flight technique for saw log classification using signal processing

   University essay from Uppsala universitet/Signaler och System

   Author : Sean Chuong Le Hoang; [2015]
   Keywords : Time-of-Flight; ultrasonic; saw log;

   Abstract : The thesis project is aimed to automate ultrasonic Time-of-Flight (ToF) technique for saw log classification using signal processing. The ToF technique works in such a way that ultrasonic tone-burst pulses are sent into a saw log, and then the ToF that the pulses take for the propagation is measured and used to calculate the sound speed and further, the Modulus of Elasticity (MoE).

3. 2. On The Performance Of Two-Way Amplify-And-Forward Relay Networks

   University essay from Blekinge Tekniska Högskola/Sektionen för ingenjörsvetenskap

   Author : Le Nam Hoang; [2010]
   Keywords : two-way relay; amplify-and-forward; symbol error rate; average sum-rate; outage probability;

   Abstract : The new paradigm of cooperative communications is a promising resolution to carry out MIMO technique. In this thesis work, we study the performance of cooperative relay networks in which the transmission from a source to a destination is assisted by one or several relaying nodes employing amplify-and-forward (AF) and decode- and-forward (DF) protocols.
