因此，在数据通信系统中不必发送训练序列，可以提高信道效率，同时盲均衡技术还可以获得更好的均衡性能。

So in the digital communication system a training sequence isn't transmitted, which can raise the channel's efficiency.

我们因为接收机故障盲发…，下次发送时间…

Transmitting blind due to receiver failure… next transmission at (time).

我也不希望有人收到10个一模一样的，那很愚蠢，但我也没办法保证按比例发送，否则就不叫盲盒了。

I dont want anyone getting 10 of the same, thats just stupid, but I cant promise a balanced load out either, or it aint blind etc.
