In this paper, we propose an eigen domain transmission scheme (ETS) to establish reliable and effective communication for multiple-input-multiple-output (MIMO) systems suffering from narrowband interference (NBI). At the transmitter, assuming that the statistical information of the NBI is known, a precoding is developed to divide the channel into multiple subchannels in the eigen domain of the NBI. Then, the transmission scheme is designed to increase the system capacity by exploiting the difference among the subchannels. Specifically, we design a practical eigen domain coding (PEC) scheme for the MIMO system. Compared with the eigen domain interference rejection combining, Simulations show that the proposed ETS has about a 0.8 dB gain for the single-input-multiple-output system, and the proposed PEC has about a 4.5 dB gain for the MIMO system, respectively.
