RF Power Amplifier Characterization for Predistortion Linearization

The purpose of this Major Qualifying Project was to develop and evaluate a digital baseband predistortion approach for radio frequency power amplifiers (RFPA). We also aimed to develop a hardware implementation of the system. The predistorter implements a look-up-table (LUT) to restore a baseband signal constellation and is simulated using actual RFPA characteristics. The testing includes the use of MATLAB, a Xilinx Spartan-3 FPGA as a pattern generator, a digital-to-analog converter (DAC), a modulator, an RFPA, and a demodulator

Energy Demonstration Trailer Assessment

The Energy Demonstration Trailer is a mobile showcase of renewable energy and energy efficient technologies. The trailer was developed by the Habitat Research and Development Centre in Namibia, with the intention to enhance awareness of sustainable energy alternatives. Our project involved preparing the trailer for use by expanding the trailer\u27s educational capacities. We conducted three demonstrations with the trailer and assessed its performance and the audience\u27s interactions. Modifications were made to the trailer based on the assessment, along with recommendations for additional improvements
