The 3rd Generation Partnership Project (3GPP) Long Term Evolution (LTE) standard uses Single Carrier Frequency Division Multiple Access (SCFDMA), scheme for the uplink transmissions and Orthogonal Frequency Division Multiplexing access (OFDMA) in downlink. SCFDMA makes use of single carrier modulation and frequency domain equalization, it is a technique that has similar performance and essentially the same overall complexity as those of OFDM, But in OFDMA high Peak-to-Average Power Ratio (PAPR) is a major drawback. An outstanding advantage of SC-FDMA is its lower PAPR due to its single carrier structure.
