Item An initial design of an OFDM transceiver(2010-05) Thacker, Corey McKinney; Abraham, Jacob A.; Chang, HenryThe initial design of an OFDM transceiver is described and the simulations using MATLAB’s Simulink Software and other FGPA based tools are presented. All components of a modern OFDM system were implemented in Simulink to provide an understanding of the various components of an OFDM system, provide a proof of concept in the design, and measure the theoretical performance of the system. In an effort to build the transceiver, the FFT and randomizer components were implemented in verilog and were successfully simulated using ModelSim Altera Starter Edition 6.5b. A commercially available OFDM core, which did not include forward error correction, was simulated to measure the performance of an OFDM system within Altera Stratix III devices and determine the overall logic utilization for OFDM modulation and demodulation. The goals of this report are to describe in detail the general effort made by the author to build an OFDM transceiver and serve as a driver for its eventual FPGA implementation.Item System-level design and analysis of an embedded audio signal processing application(2016-05) Dollo, Philippe Marc; Sun, Nan; Akinwande, DejiIn this report, a design is proposed for an embedded system that implements an audio beamforming application. This design provides the key considerations for both the analog front-end, and the digital signal processing that would be included on-chip. The analog portion of the design implements a multi-order delta-sigma ADC, and the digital portion of the design implements a digital decimation filter and a beamforming filter. The objective of the project is to develop a system that could be used in a real-world implementation, with design decisions which attempt to account for system-wide specifications, rather than focusing on block-level performance alone.
