FRAME SYNCHRONIZATION APPARATUS, SIGNAL ANALYSIS APPARATUS INCLUDING THE SAME, FRAME SYNCHRONIZATION METHOD, AND SIGNAL ANALYSIS METHOD

摘要

To provide a frame synchronization apparatus capable of quickly detecting the start position of a frame conforming to the 5G NR standard with a simple configuration.SOLUTION: A frame synchronization apparatus 30 includes a detection unit 50 that detects one of synchronization signal blocks from an input signal c, a setting unit 60 that sets the next candidate position on the time axis of the type of synchronization signal block detected by the detection unit on the basis of first and second arrangement patterns, a determination unit 70 that determines whether the signal block of the next candidate position in the input signal is the same as the detected type of synchronization signal block each time the next candidate position is set, and a leading position identification unit 80 that identifies the leading position of a frame on the basis of the first and second arrangement patterns when the determining unit determines that the signal block at the next candidate position is not the same as the detected type of synchronization signal block.SELECTED DRAWING: Figure 1
