| Abstract: | The spread spectrum correlator is used to carry on related processing to particular code in the signal processing,the solution which completes signal decodes and get back the information of transmission.The spread spectrum correlator adopts digital process and handle the form of signal more agility,can make related process to different code type,different code length,bringing tremendous convenience for withdrawing the synchronous signals.In this paper,we designed a whole DSSS system including the correlator... |
