Abstract
In this paper, a low complexity demodulation scheme is proposed for IEEE 802.15.4 LR-WPAN systems. In the proposed scheme, multiple active correlators for demodulation are replaced with a matched filter-based cross-correlator shared with a synchronization unit, which requires only a few additional control units. Consequently, with the proposed demodulation scheme, the total hardware complexity for the LR-WPAN baseband modem is 54% less than that of the existing architecture to have the separated demodulation and synchronization units.
