| Abstract: | A wireless digital semi-duplex low power voice transceiver for short-distance communication is introduced in terms of the design of its hardware and software.Matters needing attention about the choice of the RF IC are given,and the wireless semi-duplex communication protocol and the whole system's power management are presented in detail.Meanwhile,this paper also refers to the Continuous Variable Slope Delta Modulation(CVSD)voice coding algorithm,which is adopted in the transceiver.This design achieves the anticipated goal. |
