Research of Single-Carrier Frequency Domain Equalization on DTTB

The frame structure in Chinese DTTB standard is introduced,and a channel estimation algorithm with a better performance is given according to the cycle characteristics of the signal frame head.Analyzing the advantages and disadvantages of traditional equalization algorithm for SC system,an equalization algorithm that is joint frequency domain equalization and time domain decision feedback is put forward.At last,simulation is realized according to U1 channel,and simulation results are analyzed and summarized.
