Synchronizing device and synchronizing method

摘要

The synchronization acquisition apparatus calculates a correlation value for each search code group using at least two search codes assigned to the search code group beforehand and identifies the search code group first. Then, the synchronization acquisition apparatus calculates a correlation value using at least two search codes that have the array pattern corresponding to the identified search code group and detects frame timing. At this time, at least two search codes are assigned to each search code group in such a way that these search codes do not overlap among search code groups.
