Pilot signal generating method of nb-iot pilot signal generating device

Abstract

The invention relates to the technical field of Internet of Things communication, and specifically relates to a NB-loT pilot signal generation device and a pilot signal generation method thereof. An output end of a NB-loT pilot baseband generation unit is connected with an input end of an intermediate control unit; the output end of the intermediate control unit is connected with one input end of a mixer; another input end of the mixer is connected with an output end of a first local oscillator unit; the output end of the mixer is connected with one input end of another mixer; another input end of the other mixer is connected with a second local oscillator unit and outputs a radio frequency signal; an output end of another mixer is connected with an input end of a controllable filter unit, an input end of a gain regulation unit and an input end of a fixed gain amplifier unit in sequence; and the output end of the fixed gain amplifier unit outputs a high power radio frequency signal. Compared with the prior art, the frequency coverage range of a NB-loT signal is satisfied through multi-level frequency conversion of a radio frequency channel.

Description

technical field [0001] The present invention relates to the technical field of Internet of Things communication, and in particular to an NB-IoT pilot signal generating device and a pilot signal generating method thereof. Background technique [0002] The Internet of Things market has huge potential and is about to enter a large-scale blowout development. At present, the mass consumer market is becoming more and more saturated, which has led to a slowdown in the profit growth of operators, and it is urgent to seek new profit growth points. According to reports from McKinsey and other institutions, the number of IoT connections and market size will experience a large-scale blowout in the next 5-10 years style development. The Internet of Everything has become an important strategic direction for the active deployment of global operators, technology companies and industry alliances. At present, the cellular network has covered 90% of the world's population and more than 50% o...

Problems solved by technology

The NB-IoT industry is in the accelerated stage of research and development. However, in the process of industrial development, test instruments still lag behind the development of other equipment and systems. Currently, it is difficult to see NB-IoT test instruments that can be seen in the market. And system manufacturers are currently built through a combination of various instruments, so NB-IoT instruments that promote the development of NB-IoT technology have yet to be developed

At present, the NB-IoT (R13) standard formulation work has been frozen, but for NB-IoT to achieve commercial success, early test solutions that are synchronized with standard development are required, which poses greater challenges to measuring instruments
