Sammanfattning

This paper presents a data-aided Carrier Frequency Offset (CFO) estimation algorithm targeting the Wideband OFDM systems. Utilizing 3 consecutive preambles and processing them at frequency domain, the algorithm is robust to both Frequency Independent (F-I) and Frequency Dependent (F-D) I/Q Mismatch (I/Q-M). To evaluate the effectiveness of the proposed CFO estimation technique, we conduct extensive simulations based on Multi-Band OFDM Ultra-Wide Band wireless transmission. Compared to the ideal case when the CFO has been perfectly estimated, the performance loss at 8% Packet Error Rate (PER) is less than 0.5 dB.
