In this paper, Single Carrier (SC) transmission is considered. The authors focus on SC Frequency Domain Equalization (FDE) receiver and analyze the Signal to Noise Ratio (SNR) of the time domain output signal estimate and then, derive the achievable Bit Error Rate (BER). For the purpose of comparison, they consider optimal Time Domain Equalization (TDE) receiver as a reference. Their analytical results show the relationship between the FDE and optimal TDE. In the high speed data communication, the wireless channel exhibits strong frequency selectivity due to the multi-path delay and therefore, the Inter-Block Interference (IBI) and Inter-Symbol Interference (ISI) are produced at the receiver side.
