• Communication technology of satellites has been developing with the advancement of terrestrial communication technology. The p urpose of this paper is to apply an advanced terrestrial technology to satellite communication. Because LEO small satellites are very sensitive to power budget, reducing power consumption of satellites through effective power control is important. Therefore this paper will introduce methods for improving communication reliability through a novel power control technique and through a well-known spread spectrum used by mobile communication industry. An object distinction method described in this paper uses frequency spread spectrum technique with a Walsh code as its spread code (PN code). This paper will examine generation a method of spread code, a method of modulation and demodulation, and a possible method to a reliable communication while reducing power consumption of LEO small satellites.
