1. 1. Studying Noise Contributions in Nonlinear Vector Network Analyzer (NVNA) Measurements

   University essay from Avdelningen för elektronik, matematik och naturvetenskap

   Author : Tianyang Feng; [2012]
   Keywords : nonlinear measurements; nonlinear vector network analyzer NVNA ; power amplifier; nonlinear systems; noise contributions.;

   Abstract : Noise contribution in nonlinear systems is very different from that in linear systems. The noise effects in nonlinear systems can be complicated and not obvious to predict. In this thesis, the focus was on the noise contribution in nonlinear systems when measuring with the nonlinear vector network analyzer (NVNA). READ MORE

3. 2. Disturbing Sound Cancellation Using System Identification

   University essay from Avdelningen för elektronik, matematik och naturvetenskap

   Author : Tianyang Feng; You Zhou; [2010]
   Keywords : System Identification; MATLAB; Disturbing Sound Cancellation; NMSE; Model;

   Abstract : Disturbing sound sometimes should be cancelled when music has been recorded. In this thesis, MATLAB was used as a tool. System identification was a main method used to find the unknown system. By subtracting the simulated output, disturbing sound was cancelled. READ MORE
