| Abstract: | A serial acquisition algorithm and a parallel acquisition algorithm are introduced in this paper.And the two algorithms are simulated in the case with tone-interference or without interference.From the simulation,it proves that the computation time in parallel algorithms is much less than which in serial algorithm.Acquisition algorithms' performance is analyzed in the case with tone-interference. |
