  • Patent number: 8948230
    Abstract: An IEEE 802.15.4 DSSS Offset-QPSK device is proposed that allows an existing system to transfer Offset-QPSK modulation signal into MSK modulation signal, then deliver the MSK modulation signal without DSSS to increase payload data transmission rate. On-the-fly detection of whether a low data rate or a high data rate encoding mode is used for a received frame is attained by the transmitter setting a predetermined bit in the frame length byte of a transmitting frame. Thus an extra high data rate transmission for IEEE 802.15.4 DSSS Offset-QPSK systems can be provided.
