    摘要： An enhanced bypass mode simulcast radio communication system (200) includes a plurality of transmit/receive (T/R) sites (2101, 2102, 2103) configured to participate in a simulcasting communication session responsive to a control point system (201). A site controller (211) is responsive to determination of a timing malfunction at a first one of the T/R sites. In response, the site controller is configured to automatically terminate participation of the malfunctioning T/R site in the simulcasting communication session and perform further actions to cause the malfunctioning site to transition to a multisite mode of operation involving a network switching center (202). The simulcast system automatically adjusts its site timing to compensate for the loss of the T/R site in bypass.

    摘要： A transmission system to transmit an information signal in a single-frequency network (SFN) includes a plurality of transmitters to transmit the information signal to at least one receiver, wherein at least one transmitter of the transmission system is adapted to transmit the information signal (IS) with a time offset, wherein the time offset varies over time, thereby the information signal (IS) transmitted by the at least one transmitter is received with a second time offset by the at least one receiver, in order to enhance the reception quality and minimize a signal cancelation.

    摘要翻译： 本发明涉及单频网（SFN）中的发射机，传输系统，传输方法和位移单元。 根据第一方面，本发明提出提供一种传输系统以在包括多个发射机（1）的单频网络（SFN）中发射信息信号以将所述信息信号发射到至少一个接收机，其特征在于， 传输系统的至少一个发射机（1）适于以时间偏移（4,6,7）传输所述信息信号（IS），其中时间偏移随时间变化，从而传输所述信息信号（IS） 由所述至少一个接收机以第二时间偏移接收所述至少一个发射机（1），以便增强接收质量并最小化信号消除。
