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...
