Motivated by the cell-free and massive MIMO (multiple input multiple outputs) communication scenarios, the number of power amplifiers (PA), digital to analog converters (DAC), etc., is increased. Thus, using coarse quantized transmission reduces the channel's hardware cost and nonlinear effects. More details can be found in the attached file.
In this project, we investigate algorithms for mapping modulated data to coarsely quantized signals and compare their information rates.
The student needs an understanding of information theory and communication systems.
