in many applications, it is required to monitor the activities of these signals, identify their characteristics, even to intercept the signal information content 在許多應用中,需要監(jiān)視通信信號的活動情況,區(qū)分信號的性質,甚至截獲其傳輸的信息內容。
given a received communication signal, the objective of modulation recognition is to decide the modulation format and estimate the modulation parameters of the communication signal without any priori knowledge about the signal information content 給定一段接收的通信信號,調制識別的目的就是在未知調制信息內容的前提下,判斷出通信信號的調制方式,并估計出相應的調制參數。
