Research and Review on Novel Spread Spectrum Communication Theory

摘要

With the rapid and bursting development of communication science and related technique, spread spectrum communication has been a hot research topic in the computer science and engineering community. Therefore, to follow the trend, in this paper, we conduct research on novel spread spectrum communication theory and corresponding anti-jamming applications. Primarily, multi-band spread spectrum communication is analyzed with theoretical analysis and de-composition, compared with conventional spread spectrum system under the condition of the same bandwidth can obtain higher information transmission rate or spread spectrum processing gain, greatly improving the utilization rate of frequency band, and its spectrum is closer to white noise, which has better resistance to intercept and confidentiality of information. We model our method through limit information transmission rate and the output signal-tonoise ratio increased with the increase of bandwidth according to the index law combined with the state-of-the-art techniques. Compared with other approach, our system outperforms and gains the better performance.
