Abstract

SC-FDE (Single Carrier Frequency-Domain Equalization) modulations are known to be suitable for broadband wireless communications due to their robustness against severe time-dispersion effects and the relatively low envelope fluctuations of the transmitted signals. In this paper we consider the use of SC-FDE schemes in broadcast and multicast systems with SFN (Single Frequency Network) operation where we do not have perfect carrier synchronization between different transmitters. We study the impact of different CFO (Carrier Frequency Offset) between the local oscillator at the receiver and the local oscillator at each transmitter. We also propose receiver structures able to reduce the performance degradation caused by different CFO at different transmitters. Our receivers can be regarded as modified turbo equalizer implemented in the frequency-domain, where a frequency offset compensation is performed before the iterative receiver.
