Abstract

本发明实施例公开了一种ACM切换方法、ACM切换装置及发射器，用于提高叠加编码的数据传输速率。本发明实施例方法包括：当满足ACM切换的触发条件时，ACM切换装置根据当前的系统传输性能获得待发射数据流的分层数量M和待切换的调制模式，分层数量M小于或等于待发射数据流中的业务数量，再将待发射数据流中的业务数据映射到分层数量为M的各个分层中，计算各个分层中每一层的归一化功率，使得发射器根据分层数量M、待切换的调制模式、各个分层映射的业务数据和各层的归一化功率对待发射数据流进行叠加编码并发射。因此本发明实施例提供了一种ACM切换方法，使得待发射数据流的编码信息能适配系统的当前传输性能，从而能够提高叠加编码的数据传输速率。
