Abstract

The invention provides a micro-frequency hopping method and a micro-frequency hopping multiple access communication system. The micro-frequency hopping method comprises the following steps: performingfrequency hopping on a time domain baseband signal in a frequency domain direction by taking a subcarrier frequency point as a basic unit and taking a sampling point as a basic unit, wherein the micro frequency hopping multiple access system comprises a single-user baseband signal used for micro frequency hopping, and one symbol of the baseband signal only comprises one subcarrier; and carrying out micro frequency hopping on the baseband signal of which one symbol of each user only contains one subcarrier by adopting a preset irrelevant micro frequency hopping pattern among multiple users. According to the micro frequency hopping technology provided by the invention, spectrum resources can be used more efficiently and flexibly, especially conflict-free mFSK micro frequency hopping multiple access communication is realized, the spectrum is truly and effectively utilized, and the networking complexity is simplified.

Description

technical field [0001] The invention relates to a communication technology, in particular to a micro frequency hopping method and a micro frequency hopping multiple address communication system. Background technique [0002] During World War II, the actress "Heidi Lamarr" was inspired by the piano and proposed frequency hopping communication technology, which improved the anti-interference ability and confidentiality of communication. On this basis, various frequency hopping and spread spectrum technologies such as CDMA and OFDMA And so on become the mainstream of modern communication technology, for example, commonly used 4G, WIFI and so on. [0003] However, the time and frequency granularity of the traditional frequency hopping technology is relatively large. For example, 4G OFDMA uses the time-frequency resource block (RB) as the basic unit for frequency hopping, and does not use the frequency hopping technology to its limit. [0004] On the other hand, although the cur...
