Phase noise compensation for OFDM WLAN systems using superimposed pilots
In this paper, a novel phase-error estimation technique for OFDM based WLAN system is proposed. The proposed technique utilizes superimposed (or embedded) pilots for phase-tracking within OFDM data packet. This leads to saving transmission bandwidth, which is lost in the conventional phase-error estimation schemes with dedicated pilot subcarriers. Moreover, we propose selective pilot mapping and decision feedback as different strategies of improving the performance of the proposed technique....[Show more]
