图中给出的仿真结果为 TM2 SFBC， TM3 开环MIMO， TM7 单流波束赋型， TM8双流波束赋型（固定rank 2）。

TM7单流波束赋型，采用动态beamforming加权方式，通过SRS信号计算得到下行权重，构造出指向用户的Beam pattern，在中低信噪比下 TM7单流相对于TM2 SFBC发送分集有明显增益。在高信噪比情况下，由于TM7 存在 UERS参考信号开销，因此峰值速率小于TM2.

TM8 双流波束赋型，采用beamforming加权方式同时为终端发送双流数据，与TM3开环MIMO发送方式相比，在中低信噪比下有明显增益。而在高信噪比情况下由于同样存在UERS参考信号开销，因此峰值速率小于TM3.

TM8 双流波束赋型与TM7单流波束赋型相比，在中高信噪比情况下，TM8发送双流数据，而TM7已接近峰值速率，因此吞吐率高于TM7.在低信噪比下，信道状况已不适于发送双流，因此TM8 吞吐率低于TM7. 此处TM8结果为固定双流波束赋型，而在实际产品中，此时TM8 会自适应切换为模式内的单流波束赋型发送方式以提高系统吞吐率。

因此从总体看，波束赋型发送方式相对于TM2 TM3具有明显增益。
