分析和仿真结果均表明MRT/RAS方案可以取得很好的阵列增益(Array Gain)及满分集增益(Full Diversity Gain),在相同频谱条件下,性能超过某些复杂的空时编码系统。同样我们对TAS/MMRC方案也进行了数学分析。

This technology USES antennas of other users as relays in wireless networks to achieve space diversity and full diversity gain.
这种技术利用通信网中其它用户的天线作为中继，实现“虚拟天线”的空间传输分集，从而提高系统性能。
The diversity gain is relative to the block length, and can amount to the full diversity gain only when the block length is no less than the number of transmit antennas.
分集增益的取值与分组长度有关，只有当分组长度不小于发射天线数目时才能获得满分集增益。
Keeping full diversity order gain, the design can achieve 0.5 transmission rate.
度增益情况下，实现码率为0.5的传送指标。
