Analysis and Optimization of Direct Sequence Spread Spectrum Scheme for an Unmanned Aerial Vehicle PPM Control Signal
Binary pulse-position modulated (PPM) control signal is widely used in remotely controlled unmanned aerial vehicles. It consists of data frames, which contain a synchronizing pulse followed by a number of shorter pulses equal to the number of channels N. In this paper we present analysis and optimization of direct sequence spread spectrum (DS-SS) scheme for PPM control signal protection. That s...
متن کاملRake-like Receiver Structures for Unmanned Aerial Vehicle Direct Sequence Spread Spectrum PPM Control Signal
Direct sequence spread spectrum (DS-SS) technique is widely used in modern telecommunications and it represents the latest advancement in radio control signal protection. One of the most widely used unmanned aerial vehicle (UAV) radio control systems is the binary pulse-position modulated (PPM) control system. In this paper, two structures of rake-like receiver for improvement of DS-SS binary P...

One of the most crucial elements of each country is electricity distribution networks (EDN). Awareness of accidents in EDN could be very important in the conservation and utilization of them. The accurate and periodic inspections can provide a good service to subscribers. The goal of this project is to fabricate a quad rotor, which can do an accurate and a periodic inspection. The design and im...
متن کاملControl, navigation and collision avoidance for an unmanned aerial vehicle
This article reports the development of an unmanned aerial vehicle capable of attitude estimation and stabilization through the implementation of a nonlinear complementary filter and proportional-integral rate controllers. Four infra-red sensors and an ultrasonic sensor are integrated with the main platform for the collision avoidance schemes and for altitude control, respectively. Critical mis...
