摘要

摘要: 该文提出一种特征域的传输方案(ETS)，用以提高窄带干扰下MIMO系统的容量。首先，发射端在特征域产生N路发射信息，然后根据窄带干扰信号的统计特征，通过预编码将发射信息从特征域变换至时域进行传输。在接收端，时域的接收信号再次被变换为N路特征域信号。据此，期望信道被划分为N路并行子信道，根据各子信道的干扰分布采用相对应的传输方案，以最大化干扰场景下信道的利用率。由计算机仿真可得，当系统容量为15 bit/(s?Hz)时，该文所提特征域传输方案相对于传统干扰抑制算法在22 MIMO系统中取得了约10 dB的性能增益。

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.
