  • Patent number: 8848589
    Abstract: A method for transmitting broadcast service data in a single frequency network including a Radio Network Controller and one or more base stations each with a cell including one or more sectors, the method includes: transmitting, by the Radio Network Controller, broadcast service data and a first transmission time to the base station; and transmitting, by the base station, the broadcast service data to each of its sector after the first transmission time, where the broadcast service data is transmitted to adjacent sectors sharing a common station address at different transmission times. Also, the present invention discloses a system and base station for transmitting broadcast service data in a single frequency network. With this technical solution, the phenomenon of fast fading of received signals in the prior art which occurs at adjacent edge zones of adjacent sectors in the same cell of the single frequency network can be avoided, and thus improving performance of receiving the signals.

  • Publication number: 20080317184
    Abstract: The present invention discloses a method for transmitting a synchronization signal in a mobile multimedia system. In the method, a transmitter of the system transmits a synchronization signal sequence at a regular interval. The methods includes: generating a first synchronization signal sequence; generating a second synchronization signal sequence by performing a reversible transform for the first synchronization signal sequence; and transmitting the first and the second synchronization signal sequences in cascade. By the method provided by the present invention for transmitting a synchronization signal in a mobile multimedia system, a channel with wider delay spread can be handled, more precise and stabler synchronization performance can be achieved and the channel estimation module can be helped to get more accurate channel frequency domain response.
