“…The Wide-Band or Ultra-Wide Band applications such as the multimedia services based generally on wireless sensors systems [1]- [5]. Several techniques are proposed in literature especially for digital communication based on two systems: narrow-band and multi-carrier [6]- [8]. This last are developing different technique in transmitter and receiver like Modulation, MAC protocol, Equalization, Filtering, Fading, Multi-path, and Non-Line-Of-Sight (NLOS) [7] [9].…”

In last few years, several recent developments concern a new proposed techniques of communication for WSN (Wireless Sensors Network) using a complex methods and technics. This network is considered a future platform for many applications like: medical, agriculture, industrial, monitoring and others. The challenge of this work consists in proposing a new design of transceiver for WSN based on IDWPT (Inverse Discrete Wavelet Packet Transform) in emitter and DWPT (Discrete Wavelet Packet Transform) in receiver for mono and multi users using AWGN Channel. We will propose in this paper, a new concept of impulse radio communication for multiband orthogonal communication for UWB (Ultra-wideband) applications. The main objective of this work is to present a new form of pulse communication adapted to low throughput short-range applications and is scalable according to the type of use but also the number of sensors.

“…Developing a new ratio fuze is an important way to improve the anti-jamming performance of the fuze. With the rapid development of industrial electronics technology, lots of new fuzes are designed constantly [7][8][9]. Pseudo-random frequency hopping (PRFH) fuze [7,[10][11][12][13][14][15], is a product which applies pseudo random theory [16][17][18] and frequency hopping communication technology into the radio fuze.…”

To solve the problems of poor fixed distance precision and difficult engineering implementation of the pseudorandom frequency hopping fuze, a new signal processing method for the fuze based on signal reconstruction is proposed in this study. First, the transmitted signal is used to generate a set of local reference signals for the matched filter. Then all the local reference signals are applied to coherent integrate with the reflected echo, respectively. Finally, any channel of these correlation peak values exceeding the presupposed threshold can be taken as fixed distance successfully. Furthermore, the relative speed between the missile and target can be approximately estimated by the corresponding channel number. The simulation results show that the method can detect the target precisely, which means that the problem of mismatched filter has been solved. Moreover, the method is easy to be implemented, which can greatly improve real-time property of the fuze, thus it has practical value for engineering application.
