Abstract

In LTE (Long Term Evolution) system, Primary synchronization effects calculation of physical cell identity and the recognition of full duplex mode directly. This paper presents an improved algorithm based on FFT fast correlation to realize the search for half frame data with the method of combining overlapping and segmented correlation, and make the preceding data cyclic shift to guarantee sequence integrity. The improved algorithm greatly improves the synchronization speed, and can meet the time delay requirements for time-frequency two-dimensional search. Theoretical analysis and experiments show that the algorithm can effectively reduce the amount of calculation and the synchronization time.
