摘要：
This paper proposes a partial pilot transmission method for self-interference (SI) channel estimation in full-duplex multiple-input multiple-output (MIMO) systems. In the proposed partial pilot transmission method, pilots for estimating the SI channel are transmitted in part for the total transmit antennas. For the channels where the pilots are not transmitted, the previously estimated SI channels are utilized. Compared to the conventional method where pilots are transmitted for the whole transmit antennas, even if the partial pilot transmission method has the increased SI channel estimation error, the proposed pilot transmission method can achieve about a 1 bps/Hz gain in terms of the ergodic achievable rate.
