A Chaotic Pulse Position Modulation Method for Ultra-Wideband Fuze

نویسندگان

چکیده

Abstract This paper presents a composite chaotic binary sequence that can be used for ultra-wideband(UWB) fuze pulse position modulation, which has good randomness under byte-constrained conditions. The feasibility of this UWB modulation is verified by hardware implementation. application with will increase the difficulty recognition jammer and enhance radio resistance to active interference.

Digital Communication Using Chaotic-Pulse-Position Modulation

Utilization of chaotic signals for covert communications remains a very promising practical application. Multiple studies indicate that the major shortcoming of recently proposed chaos-based communication schemes is their susceptibility to noise and distortions in communication channels. In this paper, we review a new approach to communication with chaotic signals, which demonstrates good perfo...

An enhanced pulse position modulation (PPM) in ultra-wideband (UWB) systems

Simplicity, transmission rate, and bit error rate (BER) performance are three major concerns for ultra-wideband (UWB) systems. The main advantage of existing pulse-position modulation (PPM) schemes is simplicity, but their BER performance is poorer than that of an on-off-keying (OOK) modulation scheme, and their transmission rate is lower than that of an OOK scheme. In this research project, I ...

A Planar, Layered Ultra-wideband Metamaterial Absorber for Microwave Frequencies

In this paper, an ultra-wideband metamaterial absorber is designed and simulated. The proposed absorber is planar and low profile. It is made of a copper sheet coated with two dielectric layers. Each unit cell of the metamaterial structure is composed of multiple metallic split rings, which are patterned on the top and middle boundaries of the dielectrics. The designed absorber utilizes differe...

Orthogonal Pulse Based Modulation Schemes for Time Hopping Ultra Wideband Radio Systems

Time hopping ultra wideband (TH-UWB) communication promises to be a viable technique to build a relatively simple, low-cost and 1ow-power transceiver that can be used for short range high speed wireless communication over the multipath channel. The successful deployment of TH-UWB systems strongly depends on the development of pulse waveforms, modulation techniques and system complexity. The TH-...
