在本系统中，我们首先利用比特软信息提取技术将接收到的符号软信息映射成比特软信息，然后将其送入二进制译码器进行译码。
In the proposed system, based on the soft symbol to bit mapping technique, we first get the soft bit information from the received signals and then send them to the binary turbo decoders.
在维特比译码器译码时，应用信道状态信息(CSI)，可以明显提高系统性能。
The performance can be improved greatly by using the channel state information (CSI) in Viterbi decoder.
减阶单元(80)使用该附加信息将维特比译码器(81)进行的译码限制为特定的后续阶。
The stage reduction unit (80) USES the additional information to limit the decoding by the Viterbi decoder (81) to certain subsequent stages.
目前对莫尔斯信号的译码器的研究都是针对单一信号源，信息传到PC机以后才能实现网络化传输。
Now the study of Morse signal decode is aimed at single signal source. The information can be transmitted in networks only after it is sent to PC.
