  • Apparatus and method for acquiring frame synchronization in a mobile communication system
    Patent number: 7411983
    Abstract: Disclosed is a method for acquiring frame synchronization of a broadcasting channel (BCH) in an asynchronous mobile communication system. The method comprises acquiring system timing through a synchronization channel; performing CRC by demodulating for a predetermined time duration a primary common control physical channel (PCCPCH) based on the system information, re-designating a demodulating duration according to the CRC result, and performing CRC; and acquiring frame synchronization of the BCH when the CRC is consecutively passed at least two times.

  • Apparatus and method for acquiring frame synchronization in a mobile communication system
    Patent number: 7158595
    Abstract: A method for acquiring frame synchronization of a broadcast channel (BCH) in an asynchronous mobile telecommunication system. The method according to the invention includes steps of acquiring a system timing through a synchronous channel (SCH), demodulating a primary common control physical channel (PCCPCH) based on the system timing, checking a cyclic redundancy check (CRC) by decoding a predetermined time interval of the demodulated PCCPCH, and acquiring frame synchronization of the BCH by reference to the CRC checked result.
