Millimeter wave statistical SISO (single input single output) channel models have been developed based on the propagation measurement results in the three environments (Living, conference, and cubicle room). They were proposed to TG IEEE802.11ad, and adopted as the channel model for performance evaluation. The measurements results show that the cross polarization interference is small enough for MIMO transmission. Using the above-mentioned results, the MIMO transmission simulation program using ray-tracing have been developed for performance evaluation. The orthogonal linear polarization based 2X2 MIMO transmission scheme has been proposed and the simulation results show that the proposed MIMO scheme can achieve good BER performance using simple ZF (Zero Forcing) scheme and directional antenna with the beam width less than 30 degree without the equalizer. They also show that circular polarization based MIMO can achieve more stable performance than linear polarization and demonstrate feasibility of 10Gbit/s PAN.

根据毫米波在客厅、会议室和隔间三种环境中的传播测量结果，建立了毫米波统计SISO(单输入单输出)信道模型。它们被建议给TG IEEE802.11ad，并被用作性能评估的信道模型。测量结果表明，对于MIMO传输，交叉极化干扰足够小。利用上述结果，开发了基于光线跟踪的MIMO传输仿真程序，用于性能评估。提出了一种基于正交线极化的2×2 MIMO传输方案，仿真结果表明，该方案可以在不使用均衡器的情况下，利用简单的ZF(Zero Forcing)方案和波束宽度小于30度的定向天线获得良好的误码率性能。实验结果还表明，基于圆极化的多输入多输出系统比基于线极化的多输入多输出系统具有更稳定的性能，并验证了10Gbit/S PAN的可行性。
