چکیده
Abstract A novel equalizer for single carrier Digital Television Terrestrial Broadcasting system is proposed. Because of the state-of-art equalization normally uses frequency domain DFE scheme, herein, we suggested combining with a maximum ratio combing (MRC) receiver diversity block and accordingly a frequency domain maximum ratio combing decision feedback filter (FD-MRC-DFE) structure is obtained. The theoretically optimal filter coefficients are also presented. Field test of Chinese Digital Television Terrestrial Broadcasting (DTTB) single carrier system adopting this method was carried out to validate its performance. The performance promotion is proved by the test result which shows that the proposed mechanism has practical value to apply in reality receiver.
