Design of Microstrip Lowpass Filter in Combination with Defected Ground and Defected Microstrip Struosed here to design of a lowpass filter with elliptic roll-off. The unit cell of DGS unit consists of one rectangular slot and two square shaped slots connected by two thin slots underneath the microstrip line on the ground plane. The passband insertion loss has been improved to 0.2 dB using High–Lo

Adaptive Power Control Scheme for the Cognitive Radio System Based on Receiver Sensitivityf assigned licensed spectra; though some tradeoffs exist to protect the licensed primary user communication and to enhance the throughput of unlicensed secondary cognitive user. Through spectrum sensing and power control scheme, this issue can be addressed well as it allows the cognitive user to acc

Performance Analysis of RTS/CTS Protocol in Accessing Control Channel in Distributed Cognitive Radioe. For simultaneous sharing of channels by primary users (PUs) and secondary users (SUs), the white space has duration of approximately 50 ms. In distributed cooperative sensing, the SUs perform RTS/CTS protocol with distributed coordination function (DCF) for accessing common control channel to sha

Identification of Protein Coding Region of DNA Sequence Using Multirate Filternsform (DFT) technique is most popular method for period-3 peaks identification for long time which generates various harmonics; generally known as 1/f noise along with sharp peaks, which may lead to false predication of coding region. Previous researchers used different types of filter to suppress
