OSM OAM

We have performed filtering of long data sequence using overlap-add(OAM) and overlap save (OSM) method.These techniques are block processing techniques. Because input data sequence is divided into small blocks on which operation is performed. This operation in OAM is linear convolution and circular convolution in OSM.OSM and OAM are used to find the output of  FIR filter.

    Discrete convolution of very long signals can be efficiently calculated using these methods.However the disadvantage of these methods is they introduce group delays in the system.
