Abstract:

In this paper, a new carrier frequency offset (CFO) estimation algorithm is proposed for MIMO-OFDM based wireless local area network (WLAN) systems, IEEE 802.11ad. The existing hardware-efficient auto-correlation scheme which subsamples the short train symbol can be used for low-complexity. However this method has a limitation of performance degradation. Therefore, we combine the subsampled auto-correlation scheme in a decision-directed (DD) method for the performance improvement. We show that the proposed scheme improves BER performance about 3dB with reasonable complexity increase.
