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

Abstract

The invention relates to an E-band wireless transmission signal generating device, which converts an Ethernet frame into a media access frame through a high-speed Ethernet interface, and connects it to a digital baseband processing module; the digital baseband processing module completes data encoding, and converts the encoded data Mapped to digital symbols, the data is encapsulated into an E-band frame structure, and then the sending filter module completes shaping filtering and rate conversion, and is connected to the digital intermediate frequency module; the digital intermediate frequency module converts the digital baseband signal into a digital intermediate frequency signal and inputs it to the DAC and RF front-end to generate E-band wireless transmission signals and transmit them by E-band antennas. The invention is not only compatible with multiple modulation modes, but also satisfies the requirement of high-speed 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...
