| Abstract: | Based on the characteristics of received sample data in the TD-SCDMA system, this paper combines the processes of polynomial regression reasonably and chooses the optimum partial sample data according to it. Traditional polynomial regression is not suitable for mobile system u-nit-processing timely for its large calculation. This paper proposes a common arithmetic that is suitable for mobile system, analyses correlated parameters' effect on the fitted model, and points out the ways of minimizing the whole calculation and he aspects needed to be improved. Research proves that the proposed method can enhance the probability of choosing the optimum partial sample data. |
