Abstract

Abstract

This paper proposes an Eigen domain Transmission Scheme (ETS) to enhance the capacity of MIMO systems under NarrowBand Interference (NBI). First, the transmitter generates N branches of data streams in the eigen domain, then, according to the statistical characteristic of the NBI, the eigen domain signal is transformed into the time domain for transmission. At the receiver, the received time domain signal is transformed into the eigen domain again. Thereafter, the desired channel is divided into N parallel subchannels, to maximize the capacity of the interference channel, the transmission scheme of each subchannel is determined by the power distribution of the NBI. Simulations show that when the capacity is15 bit/(s?Hz), the proposed eigen domain transmission scheme has about 10 dB gain over the traditional interference rejection algorithm in the22 MIMO system.
