| The Spread-spectrum technique is a kind of technology of information transmission. It spreads the spectrum by using the code unrelated with the information and makes its bandwith much wider than that required. In the paper, we analyzed characteristics of the pseudo-random sequence based on the spread spectrum communication. The related knowledge of m sequence and Gold sequence were introduced. First, basic theory of spread spectrum communication, working principle and category of spread spectrum system were briefly expounded. Secondarily, the properties, principle, hardware circuit and self-correlated and related randomicity of m sequence and Gold sequence were investigated in detail. Finally, we proved that these properties theory on the basis of application of Matlab simulation produced m sequence and Gold sequence and verify their properties. The related images were obtained and compared using simulated program of m sequence and Gold sequence at the same time. |
