Abstract

本发明实施方式提供产生交织器/解交织器的方法及应用。产生交织器的方法包括：设置有基交织器的交织信息和/或基解交织器的解交织信息，通过对基交织器的交织信息分别进行循环移位变换，产生多个不同的交织器。或者产生交织器的方法包括：从解交织信息中推导获得基交织器的交织信息，通过对推导获得的交织信息进行循环移位，产生多个不同的交织器。实现交织的方法包括：将各用户的需要进行交织的数据帧输入基交织器，并将基交织器输出的数据帧进行循环移位，实现交织；其中，不同用户对应不同的循环移位；或者实现交织的方法包括：将各用户的需要进行交织的数据帧进行循环移位，所述循环移位后的数据帧输入基交织器，实现交织；其中，不同用户对应不同的循环移位。
