Spread Spectrum Communication Based on Multi-DSP Network and Software Radio

The technology of spread spectrum communication has excellent performance at the spectrum efficiency,secure communication and anti-jamming communication. The combination of the spread spectrum communication theory and SDR has been an emerging research direction in communication domain in nowadays. This article introduces the platform design of the spread spectrum communication system,proposes a kind of idea about generating software of m-sequence,and gives the method which can generate pseudo-random code by multi-DSP network and attaches some source code,which has certain practical value. And in this article the hardwares in this system are analyzed,work principium is introduced and partial software and procedure chart have been given.
