| Abstract: | This paper analyzes the effect of different threshold comparison decision principle on TMA performance under the circumstances of one-path AWGN channel, using MF acquisition. The simulation result of TMA is offered and discussed. Meanwhile, the application conditions of each threshold setting principle are given to supply reference to design and realization of the acquisition system. |
