【Abstract】 A direct sequence spread spectrum modulating chip STEL-2000A is introduced in this paper. Then the design of a spread spectrum data transmission communication device is discribed which is based on this chip, and controlled by a 16-bit single chip processor 80C196. Finally, the design and realization of the hardware and software are introduced.更多还原
