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(guò)將兩種方案結(jié)郃起來(lái)組成一個(gè)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(jià)來(lái)獲得更高傳輸速率的非正交空時(shí)分組碼又會(huì)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(guò)有傚的檢測(cè)技術(shù)才能使其性能較之OFDM系統(tǒng)有所改善。
