In this paper, the equilibrium issue exists in the single carrier mobile digital TV signal processing is discussed first, and in order to improve the balance performance, how to make equalizer switch automatically between blind equalization algorithm and decision oriented algorithm is researched.Otherwise the architecture of adaptive switch between blind equalization mode and decision oriented mode based on single carrier receiving is also given.In this paper, the equalizer mode switching algorithm with double expected threshold is put forward, and the expected output error is used to control the switching between two equalizer modes.It guarantees the smooth switch of equalizer mode and reduces the convergence error.The simulation results show that with a suitable expected threshold, compared with predecessors of switching algorithm, the algorithm put forward in this paper can enhance the performance in some way.
