摘要：
Single Carrier Transmission (SCT) is a competing technique for Orthogonal Frequency Division Multiplexing (OFDM) in Broadband Wireless Systems (BWS). Recent developments in Frequency Domain Equalization (FDE) using Decision Feedback Equalization (DFE) have greatly improved the system based on the SC technique, this caused SCDFE to be selected as a candidate technique for the forthcoming BWS. This paper concentrates the growth of DFE design from scratch till its present form used in SCT and thus restricts our survey to the development of DFE for SCT. A new SCT-DFE modified model is also presented and compared with OFDM, both simulated for WLAN system. This presented equalizer structure performs better than OFDM and improves its performance when the number of iterations is increased. SC-LE and SCDFE both supersede the performance of OFDM.
