在已有的端点效应评价指标的基础上,给出了端点效应有效数据的定义.基于此定义,引入了信号分解序列的量化评价指标,进一步提出了基于有效数据的端点效应评价指标.通过调幅调频仿真信号分别对端点效应有效数据和基于有效数据的端点效应评价指标进行了说明和验证,结果表明,端点效应有效数据的提出是合理的,基于有效数据的端点效应评价能够有效地减少计算所需的信号容量,提高端点效应评价精度.

On the basis of the old end effect evaluating indicator,the definition of the end effect valid data is defined.And the quantity evaluating indicator for the signal decomposition sequence is imported.Then the valid-data-based evaluation of end effect is proposed.A AM&FM signal is introduced to the study.Applied the end effect valid data and the valid-data-based evaluation of end effect to the simulation signal respectively,the result shows that,the end effect valid data is defined rationally,and the valid-data-based evaluation of end effect can reduce the data capacity for computation and improve the evaluation precision.
