Microwave and millimeter wave communication signal generation method based on frequency doubling mode

Abstract

The invention discloses a microwave and millimeter wave communication signal generation method based on frequency doubling mode. According to the method, a microwave and millimeter wave communication signal generation device is adopted, complexity of generation of microwave and millimeter wave communication signals is reduced through a frequency doubling principle and in combination with a baseband processing algorithm, and thus, the microwave and millimeter wave communication signals are generated. The microwave and millimeter wave communication signal generation method based on frequency doubling mode breaks the traditional frequency mixing mode, builds a frequency doubling scheme to realize communication signal coverage microwave and millimeter wave band communication, greatly reduces complexity of the communication signal generation device, and provides a new means for research and development of future wireless communication systems.

Description

technical field [0001] The invention relates to the field of microwave and millimeter wave communication, in particular to a method for generating microwave and millimeter wave communication signals based on a frequency multiplication method. Background technique [0002] The rapid development of mobile communication has brought infinite convenience to people. 4G communication has been officially commercialized, but the technology will continue to evolve, and 5G communication has been put on the industry's agenda. On February 11, 2015, the IMT-2020 (5G) promotion group held a 5G concept white paper conference in Beijing, focusing on the research results of 5G requirements, technologies, and spectrum. The follow-up focus will enter the standard formulation stage. At present, domestic system manufacturers such as Huawei, ZTE, and Shanghai Bell are doing technical research and drafting standards. Internationally, countries such as Europe, America, South Korea, and Japan are al...

Problems solved by technology

[0005] At present, there are two traditional methods for microwave and millimeter wave communication signal generation devices. One is to directly perform IQ modulation on microwave and millimeter waves. In particular, the 90-degree phase shifter index in the microwave and millimeter wave IQ modulator is difficult to control; another way is to mix the microwave and millimeter wave sine wave signals to generate microwave and millimeter wave communication signals after performing IQ modulation at low frequencies. Advantages Index performance is good, disadvantages are complex structure and high cost
