| Abstract: | To solve the aerial-radio' s existing problems of low of anti-jamming performance and poor encryption, a research scheme for a spread spectrum and de-spectrum unit of data-transmission radio which is based on Stel-2000A is put forward. The scheme implementation at the transmitter and receiver is described in detail. The parameters of spread spectrum disposal gain and the bit error rate of an IF intermediate frequency unit are tested and analyzed. The test and measurement by utilizing this scheme prove that the design can meet the technical needs. |
