Vlsi design of reconfigurable filter for high speed application

The design of future multi-standard systems is very challenging. Flexible architectures exploiting processing commonalities of the different set of standards cohabiting in the device offer promising solutions. This paperpresents a graphical approach for the optimization of multi-standard Software Defined Radio (SDR) systems. The potential of our approach for optimizing multi-standard SDR systems is highlighted by considering a realistic example of channelizers for SDR systems. In this paper we compare several channelization techniques. Computational complexity for multi-standards, multichannels channelizers is presented that is to be included for the optimization procedure of flexible systems. Results show that Frequency Response Masking (FRM) technique is most suitable as
