| Abstract: | Described in this paper is a method with coherent detection to receive weak signals by using a micro-controller.6.25Hz is choosed as the carrier frequency which would be modulated in 2DPSK.This is suitable for data trans- mission from deep wells underground.The received signal to noise ratio could b(?) less than-6 dB.The code rate transmitted is 0.781 25 Baud. |
