This paper proposes a new differential-detection scheme for IEEE 802.15.4 BPSK receivers. The proposed detection scheme derives not only the decision variables for data detection but also a timing signal ready for synchronization by a simple technique. A receiver architecture based on the new detection scheme is then proposed. Based on simulation results on the receiver performance, it is shown that with a conventional radio-frequency front end the receiver could meet at a big margin the sensitivity requirement of the IEEE 802.15.4 standard.
