Digital signal processing takes its place in the field of research as digital systems are taking over the world. The digital filters form the important part of any digital system. Digital filter realizations are improving each day. Commonly designed digital filters use higher order of filter to achieve narrow transition band. One of the applications of narrow transition band filters may be for the user equipment (UE) that uses LTE-Advanced (long Term Evolution) technology. Carrier Aggregation is one among the significant mechanisms of LTE-Advanced. It provides for the wide bandwidth so that the capacity can be increased. Narrow band filters may be used for extracting the desired signal from this wide bandwidth. This paper explores the narrow band FIR filters with the introduction of the small transition band

Filtering Approach

An efficient FFT interpolation scheme, using the concept of multirate digital filtering, is presented in this paper. The method relies on a block representation and employs a parallel implementation. Timing comparisons show that this method is faster than the conventional FFT technique demonstrated by Gold and Rader. In addition, it permits a shorter word length, smaller memory size, and is well suited to seismic data processing. Application of this method to common‐depth‐point trace summation (“stacking”) is illustrated.
