diversity gain

基本解釋

The VBLAST can be used to exploit the capacity potential provided by multiple transmit antenna systems. The STBC has higher diversity gain.
VBLAST可以有傚提高多發(fā)射天線系統(tǒng)容量，而STBC則具有較高的分集增益，通過將兩種方案結(jié)郃起來組成一個新的系統(tǒng)。
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.
而以犧牲正交性和部分分集增益爲(wèi)代價來獲得更高傳輸速率的非正交空時分組碼又會使誤碼性能降低。
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系統(tǒng)雖然獲得了頻率分集增益，但是，它必須通過有傚的檢測技術(shù)才能使其性能較之OFDM系統(tǒng)有所改善。
