    摘要： A method and pre-corrector for correcting signals in radio frequency links are provided. The method comprises: obtaining, in a time division order, a set of pre-distortion vectors for the respective radio frequency links by using one and the same set of pre-distortion vector obtaining means based on difference in arrival time of cyclic delay frames in the respective radio frequency links of a multiple input multiple output (MIMO) system; and correcting a subsequent signal in the respective radio frequency links by using the set of pre-distortion vectors corresponding to that radio frequency link. With the present invention, it is only required to scan a frame header once to generate an error vector table for the input signal across the entire dynamic range of power. The device can be reused by utilizing the cyclic delay frame structure, so as to achieve high linearity of a radio frequency header.

    摘要： A link fault handling method and a data forwarding apparatus are provided herein. The method includes: A first data forwarding apparatus keeps a neighboring relation with a second data forwarding apparatus after a link between the first data forwarding apparatus and the second data forwarding apparatus fails intermittently. The link between the first data forwarding apparatus and the second data forwarding apparatus fails intermittently in this way: A first fault detecting module in the first data forwarding apparatus receives no fault detection message from the second data forwarding apparatus at a preset time of receiving the message, but receives the fault detection message from the second data forwarding apparatus in an intermittency period after the preset time of receiving the message.

    摘要： A method for advertising routing information by a routing device includes: checking whether a routing device is active; by the routing device, generating routing information, and marking the routing information with a check result; and advertising the routing information. With the present invention, a route attribute of routing information is set, so that the routing information can reflect the active or standby state of the active routing device and standby routing device; after the routing information is advertised, the routing of a remote routing device is affected. Thus, the remote routing device always selects the active routing device to forward packets, which ensures the reachability and connectivity of the network.

    摘要： The invention discloses an antenna, which comprises a reference ground, a first radiation branch and a second radiation branch. The reference ground comprises a first grounding point and a second grounding point; the first radiation branch is connected to the reference ground via the first grounding point; the second radiation branch is connected to the reference ground via the second grounding point; wherein a slot is formed between the first radiation branch and the second radiation branch, and a distributed capacitance for coupling a signal is formed by coupling the first radiation branch and the second radiation branch via the slot; a connecting point is a feeding point via which one end of the second radiation branch for coupling the signal is connected to a radio frequency (RF) feed line, the feeding point arranged between the first grounding point and the second grounding point. The antenna of the present invention has advantages as follows: since a coplanar wave-guide coupling structure is used between the antenna resonant branches, which is equivalent to a capacitance loading, and a field loaded by the distributed capacitance is mainly concentrated in the air, thus a power loss caused by a resistor in a device after a lumped parameter capacitor is loaded is avoided. Therefore, the resonant frequency of the antenna and the size of the antenna are reduced.

    摘要翻译： 本发明公开了一种天线，其包括参考接地，第一辐射支路和第二辐射支路。 参考地包括第一接地点和第二接地点; 第一辐射支路通过第一接地点连接到参考地; 第二辐射支路经由第二接地点与基准接地连接; 其中在所述第一辐射支路和所述第二辐射支路之间形成狭缝，并且通过经由所述槽将所述第一辐射支路和所述第二辐射支路耦合而形成用于耦合信号的分布电容; 连接点是用于耦合信号的第二辐射支路的一端连接到射频（RF）馈电线的馈电点，馈电点布置在第一接地点和第二接地点之间。 本发明的天线具有以下优点：由于在天线共振分支之间使用共面波导耦合结构，其等同于电容负载，并且由分布电容负载的场主要集中在空气中， 因此避免了在加载集总参数电容器之后由器件中的电阻器引起的功率损耗。 因此，天线的谐振频率和天线的尺寸减小。
