Single Carrier Frequency Division Multiple Access (SC-FDMA), is a single carrier technique that has recently received much attention as an alternative to orthogonal frequency division multiple access for 4G technology. SC-FDMA has been adopted for uplink transmission technique in 3GPP Long Term Evolution (LTE). For single-carrier systems with frequency domain equalization, Decision Feedback Equalization (DFE) performs better than linear equalization and has much lower computational complexity than sequence maximum likelihood detection. The main challenge in DFE is the feedback symbol selection rule.
