[Software Engineering] EFFICIENT-DECODING-OF-WATERMARKING DL : 0: 在这项工作中，我们对待这个问题的恢复正确的消息，如果额外的位（假报警）已加入的消息体中，在随机的位置。这的情况是常见的一些是与选择性嵌入水印系统典型的当人类视觉系统（或录音）注册成立，以提高质量水印系统。我们提出一个有效的解码方案使用一些修改的“维特比算法的代码。添加额外的状态表示可能的误报率和一个新的扩展算法的改进网格提出图。仿真结果表明，我们的算法在高效率的检测随机的误报率很高。-In this work, we treat the problem of recovering the correct message if extra bits (false alarms) are added to the body of the message at random locations. This situation is common for some watermarking systems with selective embedding which is typical when the human visual (or audio) system is incorporated to enhance the quality of the watermarking system. We propose an efficient decoding scheme for convolutional codes using some modifications of‘ the Viterbi algorithm. Extra states are added to represent the possible false alarms and a new expansion algorithm of the modified trellis diagram is proposed. The simulation results show the high efficiency of our algorithm in detecting random false alarms with high rates.

[Software Engineering] DECODER1 DL : 0: Viterbi decoder is mainly used in communication systems where error detecting and correcting is so important. This based on trailis diagram decoding methos. Which will use minimum humming distance formula to predect error and get corrected data instead of the wrong one. Main use of this type of decoding is in deep space communication. This code can transmitt 8 bit of data which is encoded in 14 bits in total while travelling through the channel. Many add , compare and units are connected together in a structure which can make branch metrix to move further, in short it is to make one pathe which can be seleted while tracking back.-Viterbi decoder is mainly used in communication systems where error detecting and correcting is so important.
