The main problem in C-T/ CDMA multihop networks is that the sender is blind before sending data everytime. 在C-TCDMA方式中,最主要的问题是发送端的每次数据发送是盲目的,因而冲突概率很高。
The blind equalization is the method that just relies on the prior-information of received channel-output sequence to adjust the equalizer weights to rebuild the sending sequence without a known training sequence. 盲均衡则是一种不借助训练序列,仅利用接收序列本身的先验信息来恢复发送序列的方法。
Blind equalization can balance channel characteristics by sending statistical channel information without additional training sequence. 盲均衡技术不需要训练序列,仅依据发送信号的统计特性就能对信道特性进行均衡。
The traditional blind equalization technology uses decision to resume sending signals. It adopts threshold and belongs to the hard decision. 传统的盲均衡技术将均衡后的信号经过判决器直接判决归类,恢复发送信号,但判决器一般用阈值进行判决,属于硬划分。
