Abstract: A wireless communication device including processing circuitry configured to generate first synchronization signal measurement values by combining sets of correlation values, the sets of correlation values being based on a reception signal, and each of the sets of correlation values having a number of correlation values equal to a first accumulation count, determine whether a valid synchronization signal measurement value is detected among the first synchronization signal measurement values based on a criterion, determine a frequency corresponding to the first valid synchronization signal measurement value as a synchronization frequency in response to determining the valid synchronization signal measurement value is detected, determine a second accumulation count in response to determining the valid synchronization signal measurement value is not detected, generate second synchronization signal measurement values based on the second accumulation count, and perform an initial access operation for synchronization with a base station using the synchronization frequency.

Abstract: An operating method of a terminal performing a cell search using first and second memories for buffering input samples includes detecting a first primary synchronization signal (PSS) group from a first input sample group while buffering the first input sample group in the first memory in a first interval. While buffering a second input sample group in the second memory in a second interval following the first interval, the method detects a second PSS group from the second input sample group, and a first secondary synchronization signal (SSS) group corresponding to the first PSS group from the first input sample group. While buffering a third input sample group in the first memory in a third interval following the second interval, the method detects a third PSS group from the third input sample group, and a second SSS group corresponding to the second PSS group from the second input sample group.
