    • The objective of the invention is to increase the potential hop density of single frequency TDD radio links by allowing a set of closely located terminals to use a single channel. This is possible when transmission and reception periods of the terminals are synchronized so that the transmit period of any of the terminals in a terminal group does not overlap with the receive period of any of the terminals in the group. Synchronization is achieved by selecting at least one terminal in a hub site as a super master terminal. This terminal gives timing through a common bus to the rest of the terminals in the group These terminals use the received timing for adjusting their own timing i.e. for adjusting the starting moment and ending moment of the transmission and reception periods in such a manner that none of terminals is sending a burst while another terminal is receiving.
    • 本发明的目的是通过允许一组紧密定位的终端来使用单个信道来增加单频TDD无线电链路的潜在跳跃密度。 这在终端的发送和接收周期是同步的情况下是可能的,使得终端组中的任何终端的发送周期与组中的任何终端的接收周期不重叠。 通过将集线器站点中的至少一个终端选择为超级主终端来实现同步。 该终端通过公共总线给组中的其余终端提供定时。这些终端使用接收到的定时来调整它们自己的定时,即用于调整发送和接收周期的起始时刻和结束时刻,使得没有一个 终端正在发送突发,而另一个终端正在接收。

    • This invention relates to data transmission in a microwave link system particularly through point-to-multipoint connections. The arrangement according to the invention utilizes both frequency and time division duplex arrangement to simplify substation structures. In accordance with the invention a substation transmits at different times than it receives, and uses different frequencies for the transmission and reception. The central station, in turn, includes a duplexer unit, whereby it can both transmit and receive simultaneously when the transmission and reception frequencies are sufficiently apart. Such an arrangement achieves advantages of the time division duplex arrangement, such as e.g. an inexpensive substation structure, without the drawbacks related to the time division duplex arrangement.
    • 本发明涉及微波链路系统中的数据传输,特别是通过点对多点连接。 根据本发明的装置利用频率和时分双工布置来简化变电站结构。 根据本发明,变电站在与其接收的不同的时间进行发送,并且使用不同的频率进行发送和接收。 中央站又包括双工器单元,当发送和接收频率充分分开时,它可以同时发送和接收。 这种布置实现了时分双工布置的优点,例如, 廉价的变电站结构,没有与时分双工布置相关的缺点。
