The azimuth azimuth is a polar angle on the x-y plane, and a positive value indicates that the viewpoint is rotated counterclockwise.The line of sight starts at the center of the frame and points to the camera.MATLAB uses azimuth and elevation angles to define the line of sight.These angles are measured in a three-dimensional coordinate system with the origin at the center of the frame.

FPGA implementation partitioning based on deliverable’s objective and tradeoffs.
Using 802.11ax baseband design, this presentation demonstrates a workflow for wireless system design that utilizes MATLAB ®, Simulink ® modeling, and embedded and HDL coders as a unified tool set for rapid prototyping. We discuss software vs. Today’s SDR hardware and software tools will need to be enhanced to enable new wireless capabilities as well as implementation optimizations that can address the strict TSN requirements. The development of wireless TSN technologies is still in the initial exploratory research stage, but as research and standards evolve, new experimentation platforms, especially SDR-based, will be required to validate the research in practice. For instance, several latency optimizations were developed using this platform, including parallelization techniques for binary convolutional codes, low-latency streaming Fourier transforms, and tightly pipelined transmit and receive processing chains. This SDR platform enables the development of techniques to optimize latency in FPGA and application-specific implementations. We have recently demonstrated an 802.11ax baseband experimental implementation (with select features) on an Intel Arria 10 FPGA platform integrated with an off-the-shelf analog front end. Next-generation Wi-Fi being defined by the IEEE 802.11ax Task Group introduces several features and capabilities that can significantly improve the support for industrial automation applications. This presentation introduces a wireless platform for experimental work in the Wi-Fi physical layer.
However, in order to experiment with time synchronization and other TSN features that control latency and reliability over the wireless medium, it is fundamental to have access to lower level MAC and PHY layer implementations. Feasibility demonstration using hardware platforms is a required step before wireless technologies can be adopted in soft and hard real-time industrial applications. Wireless Time Sensitive Networks (TSN) is an emerging research area, which can enable new applications and services for many industrial automation systems that rely on time-synchronized (and timely) communication among sensing, computing, and actuating devices.
