INITIAL ACQUISITION AND FRAME SYNCHRONIZATION IN SPREAD SPECTRUM COMMUNICATION SYSTEM |
摘要 |
A device for rapidly performing initial acquisition and frame sync of a received signal for a receiver in a CDMA communication system. To this end, the base station multiplies a spreading sequence for a pilot channel by a sync pattern which maintains the same value for a sequence of a short period and for one period of this sequence but has different value at a boundary of one short sequence period. A mobile station initially calculates the spreading sequence of the short period and the correlation value to perform initial acquisition, and despreads N-chip duration around a boundary of the one short spreading sequence period to detect the multiplied pattern, thereby to acquire sync of a data frame.
