Speeding up the synchronization of pseudorandom signals by a system comprising a convolver and a recirculation-type delay line
Abstract
An algorithm is proposed for the multistage search for pseudorandom signals (PRSs) by a system comprising an acoustoelectronic convolver (AC) and a recirculation-type delay line (RDL). The algorithm is based on the dependence of the maximum output signal of the RDL on the time mismatch between the received PRS and the recirculation period. The noise immunity of the proposed algorithm is evaluated, and it is shown that the proposed AC-RDL system can speed up considerably the synchronization of long-duration PRSs.
