Abstract

本发明的实施例提供一种数据发送和接收的方法、装置及***，涉及通信领域，该方法包括：接收通用公共无线接口CPRI帧，从所述CPRI帧中获取控制字CW和天线载波I/Q数据，其中，所述天线载波I/Q数据包括第一I/Q数据；对所述CW进行调制，得到调制后的CW；将所述第一I/Q数据复制成两部分，对第一部分进行调制，得到调制后的第一I/Q数据；判断微波信道的信道质量是否满足要求，如果所述微波信道的信道质量不满足要求，根据所述调制后的第一I/Q数据和所述调制后的CW生成第一微波空口帧，通过所述微波信道将所述第一微波空口帧发送出去。本发明实施例能够满足微波***的传输距离，且频谱利用率高。
