Abstract :
This paper presents a low-complexity differential detection scheme for the IEEE 802.15.4 O-QPSK signals. The proposed scheme utilizes a novel additive decision metric to perform symbol-level detection. Corresponding low-complexity receiver architecture is also developed. Compared with traditional MBDD chip-level detector, the proposed scheme achieves a performance improvement of 2.1 to 3.5 dB. In the meantime, the complexity does not increase much.
