The technology scheme,the performance indicators and requirements of the software and hardware are presented in details.To begin with, a deep research in spread spectrum communication technology which includes its theoretical basis,mathematical model and physical model is done. After compared the advantages and disadvantages of frequency hopping spread spectrum system and direct sequence spread spectrum system, the later is selected to be the spread spectrum approach of the radio station.On the hardware work, the circuit schematic and printed circuit board layout design of the radio station which uses ATmegal28L as its control unit and CYRF6936 spread spectrum communication SOC as its RF core is completed in the Altium Designer.
