摘要：
This paper documents the development of a hardware platform for digital voice communication in the 2.45 GHz band. The design is centered around an ADF7242 transceiver, applying IEEE802.15.4 modulation. Furthermore, the design works half-duplex and is capable to communicate alternating in both directions. On the transmit side, the sampled audio signal is processed by means of software written in C, running on the on-board microcontroller, which transmits the data to the transceiver over its SPI bus. On the receiving side, the opposite occurs. The received audio data goes to the DAC with a sample rate of 16 kHz, connected to an amplifier and speaker. Successful real-time digital voice transmissions were demonstrated with the prototype boards.
