Single Carrier FDMA又称SC-FDMA或者DFT-Spread-OFDM是3GPP LTE最新提出的适用于上行传输的一种新方案。相对于OFDMA（主要用于下行），其最大的优势在于低峰值平均功率比（即PAPR）。本程序包括OFDMA，SC-FDE（单载波频域均衡）以及SC-FDMA程序，接收端采用经典的ZF和MMSE检测算法，程序短小精悍，相当经典，方便该领域的人学习与研究。

PERFORMANCE ANALYSIS OF OFDM
Orthogonal Frequency-Division Multiplexing (OFDM) — essentially identical to Coded OFDM
(COFDM) — is a digital multi-carrier modulation scheme, which uses a large number of closely-spaced
orthogonal sub-carriers. Ea
