摘要：In a spread spectrum receiver, a despread section despreads received signalsELI and ELQ through correlation of spread signals PnI and PnQ. An integration sectionintegrates I-phase correlation data PELI and Q-phase correlation data PELQ. A lead/lagaddition section adds, to I-phase integration data PELICc, lead/lag information
representing whether the signal output from the integration section is in a lead phase ora lag phase. A delay circuit delays, by one symbol, Q-phase integration data PELQCc andI-phase lead/lag information added integration data PELIa. A lead/lag level differenceoutput section outputs a level difference TAC between lead phase and lag phase.Further, a timing control section controls the phase of the entire loop so as to eliminatethe level difference, thus tracking synchronization of the spread signals.
