If the transform size N is a Ramanujan Number and if 2π/N ≅ 2−a, then the cosine functions can be computed by shifts and adds employing Chebyshev type of recursion.

IP in WSNs can eliminate the need of translation gateway and other similar devices used in current WSNs. It allows direct access of a commercial PDA running J2ME application to monitor data. Low-power wireless personal area networks (LoWPANs) conform to the IEEE 802.15.4-2003 standard. In this paper we propose prototype for global homecare monitoring system and design MAC for patient data. Results show the performance biomedical data delivery to the gateway.

In this paper, at first, Switching Constant False Alarm Rate (S-CFAR) processor has been improved to achieve Improved SCFAR in order to fix the false alarm rate not only in homogenous environment only with thermal noise but also in non-homogenous environment, consisting clutter edge and multiple targets in the background Gaussian noise. Then in continue, a new CFAR detector which is composed of an excisior and a Switching CFAR detector, in an environment with K distribution, has been introduced. The new detector is named an Excision Switching CFAR (EXS-CFAR). The equations have been achieved by assuming the targets in Swerling I and closed form. The simulation results confirm that the introduced processors can fix the false alarm rate in both homogenous and non-homogenous environment with less detection loss.
