The 5G goal is to provide data transfer rates per second at any time, anytime, anywhere. Through all things, our lives will have changed. People use data habits are also changing. Network voice and video, data upload and downloads have been solved, the future voice and video data are more clear and fast, the power consumption is lowered, the data interference is reduced, the data is more secure, the network experience is improved, and the current network will be Transmission and carrying capacity makes challenges, which is also the problem that the 5G era will be solved.
Many companies have launched a multi-face study for 5G technology. MIMO, intensive network, new physical layer research, millimeter wave research, and so on. But in any case, in the real physical world, some hypotheses in theoretical research often prove to be a pseudo-proposition, so prototype verification and actual environmental simulation tests have become an increasingly important tool for communication system design. So, how is the role in the Software Radio Architecture (SDR), how will the status? Jin Bains, vice president of research and development of Ni (National Instruments) RF Products, pointed out that with LabVIEW, SDR, it happened to be a heavy-medium tool in the prototype design of communication system.
However, the software radio architecture of the 5G era, in response to the demand of MIMO, intensive networking, etc., is inevitable, there is no need to have multi-process subsystems, facing many challenges, such as because the software radio architecture will contain a general processor module and FPGA real-time Processing modules, this requires different programming skills and technical capabilities, from algorithms to prototypes require too long; and there are many disciplines involved in development, mathematics, simulations, user interfaces, even FPGA, drive, control, modulation, etc. Software tools are complex, and software tools do not apply to system-level design. Therefore, developing a software radio architecture, usually has a longer learning time, and the developed product is also facing limited code multiplex problems, time and cost costs are high.
JIN BAINS pointed out in the Edicon China 2015 theme speech report, before the report, he went to China's Great Wall, and he was very sighing that human beings were greatly created. In the 5G era, as the hardware becomes smaller, the bandwidth is getting higher and higher, and the speed of operation is getting faster, the challenges facing the software in the field of test are also increasingly severe. However, there is a problem that there is a problem that there will be a solution. It will also reflect the greatness of human creativity. The LabVIEW communication system development kit is such a project, which is the same as other test tools like Ni. The next era test pioneer.
Let's take a look, how the LabVIEW Communication System Development Kit gives the challenges faced by the next generation of communication systems.
In order to realize the system, the LabVIEW communication system has a classic design process, avoiding the conventional software radio architecture as a discrete software tool, lengthy design process, and a large amount of time cost issues.
An example in the millimeter wave array is, using the LabVIEW communication system, the entire project continues to have a calendar year, compared to other development tools, more than half of the time saves more than half.
The unified design process is a major feature of the LabVIEW communication system.

Hardware perceived design environment
The design platform can not only correctly compile the algorithm to the FPGA according to the design requirements, but also provide data reference for floating point numbers to fixed-point conversion.
JIN BAINS said that combining FPGA with software, this is a very valuable study, which is more beneficial to the prototype design of the 5G era.
