GENERATION DEVICE FOR TRANSMISSION SEQUENCE, SYNCHRONIZER OF TRAINING SEQUENCE, ESTIMATION DEVICE OF CHANNEL SPACING, METHOD AND SYSTEM

摘要

PROBLEM TO BE SOLVED: To provide a generation device of transmission sequence, synchronizer of training sequence, estimation device of channel spacing, method and system.SOLUTION: The synchronizer of training sequence includes: a delay correlation processing part that performs, in parallel, auto-correlation calculation of different delay amount for a reception sequence including periodical training sequence and acquires a plurality of parallel correlation sequences; a superposition processing part that performs superposition operation for the plurality of parallel correlation sequences and acquires a synchronization correlation sequence; and a synchronization extraction part that performs extraction of a synchronization position for the synchronization correlation sequence and acquires a synchronization position of the training sequence. The synchronizer of training sequence can improve noise resistance of the training sequence.SELECTED DRAWING: Figure 3
