Abstract

In this paper we consider the use of SC-FDE (Single Carrier Frequency-Domain Equalization) 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 that are 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, which jointly compensates for the frequency offset and equalizes the received signal. Our performance results show that we can have excellent performance even for strong values of CFO.
