摘要:

针对多用户MIMO广播信道下预编码技术提出了发射端配置两根天线的改进T H预编码方案。该方法突破了传统TH预编码方案发射天线与接收天线数量的限制，并且得到了很好的分集和复用增益。仿真结果表明，所提算法在容量上接近理论容量界，且当误码率为10-2时，所提方案相比单天线THP有9 dB的增益。

Abstract:

Aiming at the precoding technique for multiuser MIMO broadcasting chan nel, an improved precoding algorithm is proposed by installing two antennas at t h e transmitter terminal. This method breaks through the restriction of the amount s of transmitting antenna and receiving antenna in traditional TomlinsonHarash ima precoding(THP) algo rithms, and obtains higher diversity and multiplex gains. According to the simul ation results, the capacity of the proposed algorithm is close to the theoretica l capacity bound. Besides, it has 9dB gain compared with the single antenna THP when the bit error rate(BER) is 10-2.
