Multi-rate coexistence scheme in DSSS O-QPSK network

This application relates to Institute of Electrical and Electronics Engineers (IEEE) 802.15.4 DSSS Offset-QPSK devices, and more specifically allowing an existing IEEE 802.15.4 DSSS Offset-QPSK system to transfer Offset-QPSK modulation signal into minimum-shift keying (MSK) modulation signal, then d...

Zusammenfassung:This application relates to Institute of Electrical and Electronics Engineers (IEEE) 802.15.4 DSSS Offset-QPSK devices, and more specifically allowing an existing IEEE 802.15.4 DSSS Offset-QPSK system to transfer Offset-QPSK modulation signal into minimum-shift keying (MSK) modulation signal, then deliver the MSK modulation signal without DSSS while increasing the rate of payload data transmission.
