We are frequently confronted with statements about the alarming rate of loss of language diversity.
我们经常听到关于语言多元性快速丧失的言论。
So it is a more wise choice to increase the transmission rate and optimize the time slot block number on the condition of keeping the full diversity order in STBC design.
在保证满分集度的前提下，尽可能提高码率，并优化时延分组数，才是多发射天线构架复信号空时分组码设计的更明智的选择。
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。
In this paper, we mainly compare the performance of the two space-time codes in many aspects, such as design criterion, transmission rate, diversity gain, code gain and arithmetic complexity etc.
在本文中，本文对这两种编码方式在设计准则、传输速率、分集增益、编码增益和算法复杂性等方面进行了较为详尽的比较研究。
Using this new scheme, higher diversity order and coding gain can be achieved than STBC at the same coding rate.
这种编码在相同的码速率下，实现了比stbc更大的分集度和更高的编码增益。
It has full transmission rate, but could not provide full diversity order.
该方案能获得最大传输速率，但不能提供最大的分集增益。
