Filed: 1999-06-24
Abstract: PURPOSE: A frame synchronization method using an optimal pilot pattern is provided which the optimal pilot pattern with the length of 2l+1 having the minimum side lobe value can be applied to frame synchronization without any change when the chip rate of 3.8Mcps is used in the upward link and downward link physical channels of a next-generation mobile communication system. CONSTITUTION: In a frame synchronization method using an optimal pilot pattern, code sequences with the slot length of 2l+1 in accordance with an arbitrary chip rate are received. These received code sequences are arranged to correspond to the slot length to perform autocorrelation based on reception positions of the code sequences. Simultaneously, the received code sequences are arranged to correspond to the slot length to carry out cross correlation based on the reception positions of the code sequences. The correlation results are observed to detect frame synchronization.
