CLOCK FREQUENCY ERROR DETECTING DEVICE |
摘要 |
A clock frequency error detecting device includes a system storage portion which stores a synchronization system based on at least one of several types of frame synchronization signals included in a received signal in which a frame synchronization signal in each frame includes a part obtained by shifting of a frame synchronization signal of another frame by a symbol by using a predetermined rule; a pattern matching portion which performs pattern matching between the received signal and the synchronization system; a symbol counter which outputs a symbol number; a timing detection portion which detects the frame synchronization signal of each frame based on a pattern matching processing result and to output the symbol number at the detection timing; and a frequency error detection portion which detects a change of the symbol number and to detect a clock frequency error of the symbol period based on the detection.
