On the impact of phase noise and frequency offsets in block transmission CDMA schemes
Block transmission techniques, with appropriate cyclic extension and employing FDE techniques (frequency-domain equalization), are appropriate for high data rate transmission over severe time-dispersive channels. However, these techniques may require accurate carrier synchronization and very stable oscillators, especially when employed in the uplink transmission of CDMA-based systems (code division multiple access) with large blocks. In this paper, we study the impact of phase noise and frequency offsets on the uplink of CDMA-based block transmission systems.
