摘要:
The present invention provides an optical communication method, comprising: performing modulation on the obtained bit stream data to generate modulated signals; performing differential encoding on the modulated signals to generate differentially encoded signals; converting the differentially encoded signals into electrical signals; and mapping the electrical signals onto optical carriers to generate optical signals for transmission. With the present invention, it is possible to enhance the system's capability of resisting inter-carrier interference without decreasing spectrum efficiency, hence improving the tolerance of existing optical communication systems towards laser linewidth, fast-changing PMD, optical fiber nonlinearity, inter-channel interference and other damages, greatly enhancing system performances.

An insulator is disclosed, which includes an insulating surface. A part of the insulating surface is applied with a conductive coating having a specific resistivity. A conductive coating region having the specific resistivity and a nonconductive coating region are configured that: in a dry environment, no continuous conductive channel exists between upper and lower fittings of the insulator. The value of the leakage current that can be caused by the conductive coating region having the specific resistivity on the insulating surface enables the insulating surface to reach an ice-proof temperature in an icing climate condition. Also, a power transmission apparatus in which the insulator is adopted is disclosed. In an icing climate condition, the conductive coating can achieve the function of increasing the value of the leakage current on the surface of the insulator, so as to prevent the ice formation.

The combinational computing method includes the steps of: receiving a first setting relating to multiple groups of input data and a second setting relating to a combinatorial mode among multiple groups of input data, obtaining the data combination of the multiple groups of input data according to the first setting and the second setting, and performing a desired calculating operation on the data combination.
摘要:
A method, an apparatus and a system for authorizing a policy and charging control rule are provided. The method includes: receiving a resource allocation request message, where the resource allocation request message indicates that a resource is allocated on a designated bearer; sending ARP information of the designated bearer to a PCRF; and receiving QoS of PCC rule authorized by the PCRF according to the ARP information of the designated bearer, and performing bearer binding according to the QoS of the authorized PCC rule. In the present invention, the PCRF acquires the ARP information of the designated bearer, so that the PCC rule authorized by the PCRF can be bound to the designated bearer, and the user equipment on the designated bearer can be successfully allocated the resource.
摘要:
A co-processor system and a method for loading an application to a local memory of a co-processor system. In the method, re-locatable code and descriptive data are copied from a loading region to a non-loading region. An executable image to be loaded is loaded using the re-locatable code copied to the non-loading region according to the descriptive data. The local memory includes a loading region and a non-loading region, the loading region stories a loader and descriptive data of an executable image to be loaded of the application, and the loader includes re-locatable code. A system is provided for carrying out the steps of the method. In accordance with the system and method of the present invention, flexibility of co-processor system application development is improved without occupying additional storage space.
