METHOD AND DEVICE FOR ACCELERATED SEARCH OF BROADBAND SIGNAL

摘要

FIELD: data processing in broadband radio communications and radio navigation. ^ SUBSTANCE: proposed method intended for use where reception of extended-spectrum data signals keyed by simulation-resistant pseudorandom nonlinear derivative sequences is always preceded by synchronization includes concurrent accumulation of periodic mutually correlated function values of signal segments arriving from output of dynamically matched adjustable filters with two standard sampling lines affording generation of random derivative, as well as determination of time step numbers of their mutual shift corresponding to delay synchronism. Then current delay of entire signal being received is found from combination of these time step numbers. Used as dynamically matched adjustable filters in search channels are acousto-electronic convolvers. ^ EFFECT: reduced time and hardware requirement for searching broadband delay signals characterized in high simulation resistance. ^ 2 cl, 9 dwg
