Study of Direct Sequence Spread Spectrum Receiver Base on Software Radio
Boli Liu · Journal of Hebei University · 2005
On the basis of software radio, a mathematics model about DSSS receiver is described,and a realization diagram of wide_scope intermediate frequency sampling DSSS receiver is builded. The design scheme about analogy preconditioning,broadband A/D converting,DDC and DSP are given according to the technical level of the chips.It′s needed to apply software radio to spread spectrum system.It is the groundwork of the reality multi_band and mulit_mode CDMA receivers be provided.
