摘要

摘要: 該文提出一種特征域的傳輸方案(ETS)，用以提高窄帶干擾下MIMO系統(tǒng)的容量。首先，發(fā)射端在特征域產(chǎn)生N路發(fā)射信息，然后根據(jù)窄帶干擾信號的統(tǒng)計(jì)特征，通過預(yù)編碼將發(fā)射信息從特征域變換至?xí)r域進(jìn)行傳輸。在接收端，時(shí)域的接收信號再次被變換為N路特征域信號。據(jù)此，期望信道被劃分為N路并行子信道，根據(jù)各子信道的干擾分布采用相對應(yīng)的傳輸方案，以最大化干擾場景下信道的利用率。由計(jì)算機(jī)仿真可得，當(dāng)系統(tǒng)容量為15 bit/(s?Hz)時(shí)，該文所提特征域傳輸方案相對于傳統(tǒng)干擾抑制算法在22 MIMO系統(tǒng)中取得了約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.
