Space division multiple access communication method based on harmonic modulation technology

Abstract

The invention discloses a space division multiple access communication method based on a harmonic modulation technology. According to the method, an adaptive array antenna is adopted to realize spacedivision and form different wave beams in different user directions, and different antenna wave beams are used to provide information access for users in different areas. The same carrier frequency ordifferent carrier frequencies used for serving different areas covered by the antenna beams adopt fundamental frequency and harmonic wave for information transmission. The information transmission process comprises the following steps: firstly, modulating different information, then respectively loading the modulated information on different harmonic components or component combinations, and finally demodulating fundamental frequency and harmonic information received by a receiving end. According to the method, the capability of harmonic information transmission is fully utilized, the utilization rate of the frequency spectrum is greatly improved, potential of the existing frequency spectrum resource is greatly mined and excited, and therefore the existing space division multiple access communication method can be greatly splendid in the upcoming 5G era.

Description

technical field [0001] The present invention relates to the technical field of communication, in particular to a space division multiple access communication method based on harmonic modulation technology. Background technique [0002] Radio spectrum (radiospectrum) generally refers to the general term for radio frequencies that emit radio waves within the frequency range of 9KHz-3000GHz. All radio business is inseparable from radio frequencies, just like vehicles must be driven on the road. [0003] The nature of the radio spectrum makes it a fundamental resource for the telecommunications industry. First, the radio spectrum is limited. Due to the propagation characteristics of radio waves at higher frequencies, radio services cannot use radio frequencies in higher frequency bands indefinitely. At present, humans cannot develop and utilize frequencies above 3000 GHz, although the use of radio spectrum can be based on time, space, frequency and Four encoding methods are u...

In this way, spectrum resources will be wasted

Especially in the current situation where the spectrum resources are so tight (especially in the coming 5G era), the spectrum resources cannot be fully utilized, then the traditional space division multiple access communication method will be eliminated because it cannot meet the current actual needs
