    Abstract: A method for mapping a secondary synchronization channel symbol in an OFDM cellular system and a base station using the same remove unclearness between other cells in a mapping proves by setting at least one of two orthogonal code sequences to an index value to add or multiply an arbitrary number to or by the orthogonal code sequence index allocated to a first secondary synchronization channel symbol and performing mapping. A first orthogonal code sequence(301) and a second orthogonal code sequence(302) allocated to the first secondary synchronization channel symbol are cross-mapped and allocated to a second secondary synchronization channel symbol. At least one of two orthogonal code sequences is set to an index value adding or multiply the arbitrary number to or by the orthogonal code sequence index allocated to the first secondary synchronization channel symbol and then is mapped. The arbitrary number is the natural number.

    Abstract: A signal transmission method and an apparatus therefor are provided to reduce the decoding delay time in a terminal, and enable a base station to efficiently manage resources. In a base station, a method for transmitting signals includes the following steps. Transmission information consisting of a plurality of frames is renewed at a transmission information update period. In each frame within the transmission information period, channel coding is performed for the transmission information by using a scrambling code. The channel-coded transmission information is converted into the transmission symbol. The transmission symbol is transmitted. In each of frames within the transmission information period, different scrambling codes are used.

    Abstract: A handover method between wireless communication systems each using a different wireless access technology and a method for transmitting a forward synchronization signal therefore are provided to perform seamless handover by providing a frame structure including an SCH(Synchronous Channel)/P-BCH(Primary-Broadcasting Channel) supporting measurement of handover. An MS(Mobile Station)(500), which communicates with a home base station(S0) acquires information such as the number of transmission antennas of a target base station, and bandwidth information(S1). The MS reports the information to the home base station(S2). The home base station inquires a target base station(520) as to whether the MS can perform handover(S3). If there is available radio resources, the target base station informs the home base station accordingly(S4). The home base station instructs the MS to perform handover(S5). The MS transmits a handover preamble to the target base station(S6). The target base station allocates resources for data communication to the MS(S7). The MS communicates with the target base station with the allocated radio resources to thus complete inter RAT handover(S8).

    Abstract: A wired link tester for checking the performance of a multiple antenna system is provided to configure wired links in response to wireless links for the multiple antenna system, thereby reproducing a status that a signal transmitted from a transmitting antenna is received to all receiving antennas. A wired link tester(120) is connected to a BS1(111), a BS2(112), a terminal(130), and an external computer(140) to configure a test environment. The wired link tester comprises a fast fading reproduction unit(200), a path loss reproduction unit(300), and a control unit(600). The fast fading reproduction unit makes the wired link tester configure 16 wired links in response to 16 wireless links for the maximum 4x4 multiple antenna system, and reproduces a status that a RF(Radio Frequency) signal transmitted from a transmitting antenna is received to all receiving antennas, and changes the characteristics of a variable attenuator and a variable phase shifter according to the control signal of the control unit to reproduce fast fading characteristics. The path loss reproduction unit forms 16 wired links with the fast fading reproduction unit, and changes the characteristics of a variable attenuator positioned at the path loss reproduction unit according to the control signal of the control unit to reproduce path loss characteristics. The control unit prestores a value for reproducing the characteristic of a wireless link and controls the fast fading reproduction unit and the path loss reproduction unit according to the prestored value.
