METHOD AND DEVICE FOR DETERMINING DELAY IN SAMPLING SIGNAL RECEIVED BY CELLULAR COMMUNICATION SYSTEM Russian patent published in 2001 - IPC

FIELD: time-division multistation-access cellular communication systems. SUBSTANCE: method used for recovering system clock synchronization with or without framing involves estimation of indirect components including information on delay in sampling complex linear vector using maximal similitude criterion and fetching of sampling delay from estimated indirect components. For fetching sampling delay use is made of optimal procedure and three suboptimal ones which are easier to calculate. These procedures are given in description of invention which also describes device implementing proposed method. Sampling delay for frame synchronization in synchronization recovery involves, in addition, a number of sampling intervals determined by maximal amplitude of signal in set of samples calculated from estimated indirect variables and sampling delay. EFFECT: improved frame synchronization, facilitated recovery of synchronization in communication system. 19 cl, 6 dwg
