Abstract
To solve the difficulty in underground communications and the problem of large signal fluctuation range in the receiver,the principle and key technologies of software radio receiver were analyzed,and a digital Voice FM un-derground communication receiver was designed. According to the signal flow,a large dynamic AGC amplifier up to 80dB was designed, the architecture of FM quadrature demodulation was provided and the voice terminal was completed. Finally,a detailed exposition of the receiver’s software design and hardware implementation were given. The whole receiver has strong anti-noise performance.关键词
