In multi-input multi-output orthogonal frequency division multiplexing (MIMO-OFDM) systems, phase tracking schemes are affected by co-channel interference (CCI) and inter-carrier interference (ICI) caused by residual frequency offset.
In this paper, we propose a feedback phase tracking scheme using iterative estimation of residual frequency offset to eliminate the effect of both ICI and CCI for MIMO-OFDM systems.
The proposed phase tracking scheme estimates the amount of residual frequency offset in the frequency domain, and compensates for it in the time domain, iteratively.
Thus, the effect of ICI can be reduced.
Furthermore, we consider two multiple channel estimation methods to eliminate the effect of CCI.
First is the method that employs midambles.
Second is the one that reuses a preamble.
Thus, the channel estimation is carried out several times within the packet, and the effect of CCI can be reduced.
Simulation results show the proposed scheme can compensates for residual frequency offset and CCI more accurately, and improve the packet error rate (PER) performance. |
