diversity gain

基本解释

The VBLAST can be used to exploit the capacity potential provided by multiple transmit antenna systems. The STBC has higher diversity gain.
VBLAST可以有效提高多发射天线系统容量，而STBC则具有较高的分集增益，通过将两种方案结合起来组成一个新的系统。
Whereas the non-orthogonal space-time block codes which obtain higher transmission rate at the cost of orthogonality and partial diversity gain may degrade the performance.
而以牺牲正交性和部分分集增益为代价来获得更高传输速率的非正交空时分组码又会使误码性能降低。
Although the additional frequency diversity gain can be attained, by using efficient detection techniques, the performance of OFDM-CDM system is better than that of conventional OFDM.
CDM系统虽然获得了频率分集增益，但是，它必须通过有效的检测技术才能使其性能较之OFDM系统有所改善。
