Comparison of Three Interpolation in OFDM Systems
Abstract: Doppler shift and channel induced fading effects are more likely to induce inter carrier interferences (ICI), which are the challenging research area in the orthogonal frequency division multiplexing (OFDM). This paper uses channel estimation for canceling the effects of ICI from the received signals. One dimensional frequency domain comb-type channel estimation are considered because of its low computational complexity and effective tracking ability of the fast fading channel. The channel …

Compare of Static and Dynamic Energy Efficient Clustering Techniques Using Fuzzy Logic in Wireless Sensor Network
Abstract: A wireless device network (WSN) often checks physical or environmental conditions and sends the collected information to a base station (BS) through network. In WSN, clustering is wide used technique for protracting network period of time as clustering is economical technique for reducing energy dissipation. Clustering joins along many device nodes to create cluster and performs election for choosing Cluster Head (CH) for all the clusters. In clustering technique CH …

Digital Pulse Compression Waveform Generation by Using of Digital Matched Filter
Abstract: Digital pulse compression is the technique for detection of the targets through radar. It is done by Matched Filter in signal processing system. The presence of signal with noise is compressed. At some finite interval of time the high peak amplitude of signal with narrow bandwidth gives the idea of the number of targets present away from the radar. Matched filter gives the signal to noise ratio at the receiver …
