Study on an anti-jamming method of spread-spectrum communication based on LT codes

Lots of information is missing in poor communication environment and the data receiving terminal cannot recover source data, therefore, this paper proposed a new anti-jamming method of spread-spectrum communication based on LT codes. This method uses the characteristics of information scattered encoding and non-rate transmission of LT codes, through the spectrum of the signals which is the direct sequence spread spectrum broadening coding. In this way it has a good link with anti-flash and anti-jamming capability. Simulation results show that under the strong interference environment, adopting the method of spread spectrum communication based on LT codes can improve the anti-jamming capability of communication system.
