AI Technical Summary
Technical Problem
In the existing technology, the design of LP-SS is not defined, resulting in insufficient synchronization accuracy and channel estimation accuracy, and serious inter-symbol interference and inter-carrier interference.
Method used
The LP-SS is designed to occupy multiple OFDM symbols and include a cyclic prefix (CP) in each OFDM symbol to improve synchronization accuracy and reduce interference.
Benefits of technology
By occupying multiple OFDM symbols and including CP, synchronization accuracy and channel estimation accuracy are improved, while inter-symbol and inter-carrier interference is reduced.
