In this paper, we propose a new dual-band filtering method for performance enhancement of the chirp spread spectrum (CSS) system in the IEEE 802.15.4a standard. The CSS signals are composed of low- and high-band signals which are alternatively transmitted in time. If we use only one conventional channel filter, the signal-to-noise ratio (SNR) performance in the receiver is degraded, because the low- and high-band signals have a different frequency characteristics. The dual-band filtering method proposed in this paper is based on two filters which are designed to be matched well with alternativ...
