Abstract: With the development of communication technology, the mine ground-penetrating wireless digital communication technology gets rapid development. The ground-penetrating communication technology is very effective in disaster relief and other emergency communications. But due to the complicated geological conditions, sometimes voice communication is restricted, the practice proves that SMS communication will get further transmission distance, more accurate information. This paper adopts the design idea of software radio, and uses the direct sequence spread spectrum, BPSK demodulation and block code encoding technology, designs and implements by DSP programming signaling and short message communication.
