Popis: In view of lack of precision in current techniques for cycle-identification in Loran-C receivers, a new method is presented for use in Loran-C receivers based on delay-locked loop trying to improve the precision of cycle- identification and describe the algorithm of the principles, design process and implementation process. Therefore, applying the DLL cycle-identification algorithm to Loran-C timing receivers, the validity and efficiency of the presented algorithm is demonstrated. Test result shows that the algorithm has higher performance of detecting the standard zero-crossing point of Loran- C pulse signal and the cycle-identification precision can really achieve ,it's performance of the algorithm is better than other cycle- identification techniques, so as to meet the requirement of modern Loran-C digital receiver designing.
