STRUCTURE OF HYBRID SYNCHRONIZATION CHANNEL, METHOD AND APPARATUS FOR TRANSMITTING SIGNAL, APPLYING AND ANALYZING THE SEQUENCE USING THE SAME

摘要

A hybrid synchronization channel structure and a method and an apparatus for transmitting signals, applying and analyzing a sequence using the same are provided to obtain synchronization information of good quality in both of a synchronous network and an asynchronous network, and perform synchronization acquisition by auto-correlation and cross-correlation mostly performed in the synchronous and asynchronous networks, thereby improving accuracy of acquired synchronization information. A primary synchronization channel includes a sequence commonly used in a communication network, and includes a repetitive structure of a sequence in a time domain. A secondary synchronization channel includes a sequence for transmission of information except control information included in the primary synchronization channel. The secondary synchronization channel also includes a repetitive structure of the sequence at the time domain. The repetitive structure is composed by inserting a specific sequence at predetermined periods in a frequency domain.
