Maximum diversitytransmission can be achieved by adopting precoder at the transmitter and equalizer at the receiver.
通过在发送端采用预编码器，在接收端采用均衡器，可以实现最大分集传输。

This system can utilize the transmission bandwidth more efficiently and achieve frequency diversity.
这种系统能更有效地利用传输带宽，实现频率分集。

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.
