This test document specifies test methodologies and performance criteria for the RF performance evaluation of WiFi mobile converged devices. The scope of testing includes Handheld, self-contained Wi-Fi/Mobile Module, Access Point, Notebook and Tablet devices that support IEEE 802.11a, 802.11b,802.11g or 802.11n [2] as well as cellular technologies. Support for IEEE 802.11 standards must be confirmed through Wi-Fi Alliance baseline certification—that is, devices tested using this test plan must first be Wi-Fi CERTIFIED for IEEE 802.11a, 802.11b, 802.11g or 802.11n [4]. Cellular technologies include GSM, CDMA, UMTS (WCDMA), LTE and TD-SCDMA. The purpose of this document is to define the test methodology for the RF testing of Wi-Fi mobile converged devices and to specify the test conditions for each test case. The testing covers client devices and access points and specifies conducted as well as radiated tests.

The Keysight Technologies, Inc. eDP 1.4 electrical performance and characterization (EP&C) software for Infniium Series oscilloscopes (see Table 2) provides you with a fast and easy way to verify and debug your eDP interface designs for embedded systems. The eDP 1.4 electrical test software is designed to be uniquely flexible to handle the wide variety of confgurations that are possible in embedded systems and pose characterization challenges. It offers the standard tests that are recommended as well as other informative tests, so it functions equally well as a validation tool. It displays the measurement data results in a flexible report format, and the report also provides a margin analysis that shows how closely your device passed or failed each test.

Shadesmar 指针。 使用系统共享内存传递消息的IPC库。 通信模式是类似于ROS和ROS2的publish-subscibe或RPC。 所需的软件包：Msgpack 注意：Pre-alpha软件。 产品特点 多个订阅者和发布者。 多线程RPC支持。 使用循环缓冲区在进程之间传递消息。 比使用ROS时使用网络堆栈更快。 分散的，没有。 允许传递序列化消息（使用msgpack ）和原始字节。 无需为消息定义外部IDL文件。 使用C ++类作为消息定义。 发布-订阅 发布者： # include # include int main () { shm::memory::DefaultCopier cpy; shm::pubsub::Publisher pub ( " topic_name " , &cpy); const uint32_t data_size = 1024 ; void *data = ma

Non-orthogonal multiple access (NOMA), an emerging technology to improve system capacity and spectrum efficiency, has attracted significant attention. In this study, the authors propose a NOMA-based downlink cooperative cellular system, where the base station communicates with two paired mobile users simultaneously through the help of a half-duplex amplify-and-forward relay. The outage performance of the system is investigated and closed-form expressions for their respective exact and asymptotic outage scheme are derived. Furthermore, they study the ergodic sum rate of the two paired users and the upper bound of the ergodic sum rate is obtained. By comparing the NOMA with conventional multiple access (MA) via numerical simulations, they have shown that NOMA can obtain the same diversity order with conventional MA, and achieve nearly the same sum rate with conventional MA. Furthermore, NOMA can offer better spectral efficiency and user fairness since more users are served at the same time, frequency, and spreading code.
