868MHz LR-WPAN 수신기를 위한 주파수 옵셋 영향 감소에 대한 연구

In this paper, we present an algorithm which decrease a frequency offset effect for 868MHz IEEE 802.15.4b LR - WPAN (Low Rate - Wireless Personal Area Network) receiver. The proposed method improve the robustness to frequency offset and receiver's stability using the multiple delay differential filter of receiver correlator.
