Problems solved by technology
[0007] However, the current E-band wireless transmission system architecture still has no standards to follow. There are a series of speed and efficiency problems in the generation of E-band signals, encoding methods, high-speed filtering, and radio frequency signal generation. They only stay in the experimental research stage and can be realized. Signal generating equipment is still very scarce

The invention relates to E-waveband wireless transmission signal generating equipment. An Ethernet frame is converted into a media access frame through a high-speed Ethernet interface, and is connected to a digital baseband processing module; the digital baseband processing module is used for finishing data coding, mapping the coded data into a digital character, encapsulating the data into an E-waveband frame structure and finishing shaping filtering and rate conversion through a transmission filtering module, and is connected to a digital medium-frequency module; and the digital medium-frequency module is used for converting a digital baseband signal into a digital medium-frequency signal, inputting the digital medium-frequency signal into a DAC (Digital-to-Analog Converter) and a radio frequency front end, generating an E-waveband wireless transmission signal, and transmitting the E-waveband wireless transmission signal through an E-waveband antenna. The E-waveband wireless transmission signal generating equipment is compatible with a plurality of modulation ways, and meets the requirement of high-rate transmission.
Description
technical field [0001] The invention relates to the technical field of E-band high-speed wireless transmission, in particular to an E-band wireless transmission signal generation device. Background technique [0002] Microwave is a common wireless communication technology. It has the characteristics of long transmission distance, large capacity, quick deployment, and strong damage resistance. It is widely used in the relay and backhaul of communication systems. With the popularity of smart mobile terminals and the vigorous development of mobile Internet in recent years, wireless data services have shown explosive growth. The conventional spectrum resources from 6GHz to 38GHz have been exhausted, and microwave communication will expand to higher frequency bands. The E-band microwave frequency band will be the main solution for cellular wireless backhaul in the future. [0003] The E-band is the microwave frequency spectrum resource with the largest channel spacing released s...
