Abstract: In this paper, the signal decomposition and synthesis technique based on FIR filters have been studied, the different data extension methods included in convolution procession have been investigated in detail, the problem involved in conventional symmetric extension method has been reported, the new symmetric extension method has been given. The experimental results show the new method performs better than the conventional methods. -
