DPS OFDM Receivers

The goal of this project was to develop a simplified fixed-point OFDM receiver, using Dynamic Precision Scaling (DPS). The fixed-point implementation of the receiver changes during the execution, depending on the channel noise level (SNR) and type.

Energy savings were estimated using a power consumption library, issued from experiments with FPGAs and ARM processors. Preliminary results show that up to 60% of the energy can be saved using this adaptive technique.

This project was part of my Master Thesis at Cairn Team.
