In this paper we introduce a new multistage filter design to implement a decimation filter for WCDMA applications. Here we use a low pass filter to design our decimation structure. Among all the window techniques the worthy window for any application is the Kaiser window and in filtering methods linear phase equiripple FIR filter dominates the remaining filters. So, in this paper we choose Kaiser Window and equiripple technique for the design of decimation filter. For these two filters performance analysis is done in terms of pass band ripples, length of filter, number of multipliers, number of adders, number of states, multiplications per input sample, Additions per inputs sample are compared with respect to single stage filter design. For single stage filter design the order of the filter is very high so, our attempt is to try various exhaustive combinations of multistage design and prove which design is the worthy multi stage approach among all the combinations by considering the parameters like filter order, complexity and multiplication rate at the output.
