实施例一
本发明实施例一提供一种分集发射的方法，如图 4中所示， 包括如下步骤： 步骤 40: 将待发射业务进行分类， 所述分类包括高优先级业务和低优先 级业务；
本发明实施例所述对待发射业务进行分类的方法包括： 根据预先设定规 则进行分类或者系统强制设定业务等级； 例如， 所述按照预先设定规则进行 分类为： 根据可靠性要求进行分类， 要求高可靠性的业务， 如语音和实时数 据等定义为高优先级业务； 要求低可靠性的业务如一般数据定义为低优先级 业务； 其中系统强制设定的业务等级高于根据预定的规则分类后的业务等级。
本发明实施例对分类方法仅做如上举例说明， 具体分类方法本发明实施 例不做限定。
步骤 41 : 将高优先级业务同时传送到第一通道和第二通道， 采用分集保 护发射， 将低优先级业务传送到第一通道或第二通道采用非分集保护发射。
其中， 所述将高优先级业务同时传送到第一通道和第二通道， 采用分集 保护发射包括： 提取高优先级业务相关信息， 例如长度， 将高优先级业务及 业务相关信息同时传送到第一通道和第二通道。
所述低优先级业务在所述第一通道或第二通道中与高优先级业务按照特 定规则组成混合微波帧发射。 所述混合微波帧中携带分集业务指针， 所述分 集业务指针用于指示分集业务起始地址和长度， 则低优先级业务与高优先级 业务组成混合微波帧时需提取高优先级业务相关信息， 如长度。 或者混合微 波帧中携带非分集业务指针， 所述非分集业务指针用于指示非分集业务起始 地址和长度， 则低优先级业务与高优先级业务组成混合微波帧时需提取低优 先级业务相关信息， 如长度。
本发明实施例由于将低优先级业务传送到第一通道或第二通道采用非分 集保护发射， 实现了最大容量传输， 例如， 将第一低优先级业务传送到第一 通道， 将第二低优先级业务传送到第二通道， 在第一通道中第一低优先级业 务与高优先级业务组成混合微波帧发射， 在第二通道中第二低优先级业务与 高优先级业务组合混合微波帧发射， 在保证高优先级业务传输可靠性的同时， 提高了频谱利用率。
本发明实施例提供的一种混合微波帧格式如下：
微波帧头 微波开销 分集业务指针 分集业务区 非分集业务区 其中， 微波帧头用于微波帧定帧用；
微波开销， 用于微波通道管理， 比如告警回传、 ATPC传递和信道质量传 递等；
分集业务指针， 用于指示分集业务起始地址和长度， 便于微波帧业务组 合和拆分； 分集业务指针的取值范围为 0〜整个业务区长度， 即分集业务区和 非分集业务区之和； 当取值为 0时， 表示微波帧中无分集保护业务； 当取值为 整个业务区长度时， 表示微波帧中全部是分集保护业务。
分集业务区： 需要进行分集保护的业务， 为高优先级业务； 该部分业务 需要同时在第一通道和第二通道传输， 达到分集保护的效果；
非分集业务区： 不需要分集保护的业务， 为低优先级业务； 该部分的业 务仅在第一通道或第二通道内传输， 与其他通道没有关联。
另一种混合微波帧格式可以如下：
微波帧头 微波开销 非分集业务指针 非分集业务区 分集业务区 其中， 波帧业务组合和拆分； 非分集业务指针的取值范围为 0〜整个业务区长度， 即 分集业务区和非分集业务区之和； 当取值为 0时， 表示微波帧中无非分集保护 业务； 当取值为整个业务区长度时， 表示微波帧中全部是非分集保护业务。
第一通道及第二通道中的微波帧数据经各自的微波发射单元调制、 数模 转换、 滤波、 变频及放大处理后通过天线发射。
本发明实施例对待发射业务进行分类， 分为高优先级业务和低优先级业 务， 对高优先级业务采用分集保护功能， 对低优先级业务采用非分集保护发 射， 实现了在保证高优先级业务分集传输可靠性同时， 有效提高了频谱利用 率。 实施例二

步骤 51 : 接收第一通道和第二通道中传输的业务；
具体实施中由微波接收单元对接收的信号进行变频、 滤波、 放大、 模数 转换和解调后输出混合微波帧数据；
步骤 52: 分离出第一通道和第二通道中的高优先级业务和低优先级业务； 本发明一种实施例所述的分离出第一通道和第二通道中的高优先级业务 和低优先级业务的方法包括：
解调第一通道和第二通道中传输的业务的混合微波帧； 所述混合微波帧 中携带分集业务指针或非分集业务指针； 根据所述分集业务指针或非分集业 务指针分离出第一通道和第二通道中的高优先级业务和低优先级业务。
步骤 53 : 输出所述低优先级业务， 以及根据第一通道信道质量和第二通 道信道质量输出两通道中信道质量相对较高的高优先级业务。 本发明实施例对分离出的低优先级业务直接输出； 对两个通道中分离出 的高优先级业务根据两个通道的信道质量选择输出， 即选择信道质量高的通 道中传输的高优先级业务。
例如， 第一通道中分离出业务 1和业务 2, 其中业务 1为非分集保护发射的 低优先级业务， 业务 2为分集保护发射的高优先级业务； 第二通道中分离出业 务 2和业务 3 , 其中业务 2为分集保护发射的高优先级业务， 业务 3为非分集保 护发射的低优先级业务， 则对于业务 1和业务 3直接输出， 若第一通道信道质 量高于第二通道， 则输出信道质量较高的第一通道中的业务 2。
本发明实施例所述信道质量包含的参数包括如下任一个或多个： 信道的 接收功率、 信噪比、 解调告警及误码率、 MSE (均方误差）等。
本发明实施例实现了在保证高优先级业务分集传输可靠性同时， 有效提 高了频谱利用率。 实施例三

本发明实施例实现了在保证高优先级业务分集传输可靠性同时， 有效提 高了频谱利用率。 实施例五
本发明实施例五提供一种分集发射的方法， 如图 10中所示， 具体包括如 下步骤：
步骤 100: 将待发射业务进行分类， 所述分类包括高优先级业务和低优先 级业务；
本发明实施例所述对待发射业务进行分类的方法包括： 根据预先设定规 则进行分类或者系统强制设定业务等级； 例如， 所述按照预先设定规则进行 分类为： 根据可靠性要求进行分类， 要求高可靠性的业务， 如语音和实时数 据等定义为高优先级业务； 要求低可靠性的业务如一般数据定义为低优先级 业务； 其中系统设定的业务等级高于根据预定的规则分类后的业务优先级。
本发明实施例对分类方法仅做如上举例说明， 具体分类方法本发明实施 例不做限定。
步骤 101：判断第一通道信道质量和第二通道信道质量是否均高于设定门 限值；
其中， 该第一通道信道质量和第二通道信道质量可以从各通道的微波接 收单元获得。 其中所述设定门限值是设定的各种调制模式稳定工作时所需要 的条件， 具体参量包括接收功率、 信噪比、 解调告警或误码率等。
若第一通道信道质量和第二通道信道质量均高于设定门限值， 则执行步 骤 102; 否则， 执行步骤 103;
步骤 102:将高优先级业务和低优先级业务分别发送到第一通道和第二通 道采用非分集保护发射；
也就是， 在确定第一通道信道质量和第二通道信道质量均高于设定门限 值情况下， 则可确定通过两通道传输业务均可靠， 则可以对高优先级业务和 低优先级业务都采用非分集保护发射。 例如， 将高优先级业务发送到第一通 道发射， 将低优先级业务发送到第二通道发射， 或将高优先级业务发送到第 二通道发射， 将低优先级业务发送到第一通道发射。

步骤 103：将高优先级业务同时发送到第一通道和第二通道采用分集保护 发射。
也就是， 在第一通道信道质量和第二通道信道质量不满足均高于设定门 限值情况下， 只传输高优先级业务， 且将高优先级业务采用分集保护发射， 即提取高优先级业务相关信息， 将高优先级业务及业务相关信息同时发送到 第一通道和第二通道发射。
此时， 若将高优先级业务采用分集保护发射， 则第一通道和第二通道发 射的混合微波帧中携带分集保护指示。

步骤 111：判断所述业务的混合微波帧中携带分集保护指示还是非分集保 护指示；
接收的混合微波帧中携带有分集 /非分集保护指针，根据该分集 /非分集保 护指针可以判断是分集保护还是非分集保护；
若携带非分集保护指示， 则执行步骤 112; 若携带分集保护指示， 则执行 步骤 113;
步骤 112: 分别输出第一通道和第二通道中的业务；
也就是， 若采用非分集保护， 则表明第一通道和第二通道传输的业务不 同， 分别直接输出两通道传输的业务。
步骤 113:根据第一通道信道质量和第二通道信道质量输出两通道中信道 质量相对较高的业务。
也就是， 若确定采用了分集保护指示， 则表明第一通道和第二通道传输 的业务相同， 则根据第一通道信道质量和第二通道信道质量输出两通道中信 道质量相对较高的业务。 所述第一通道信道质量和第二通道信道质量可以从 微波解帧单元获得。 所述信道质量包括如下参数中任一个或多个： 信道的接 收功率、 信噪比、 解调告警、 误码率、 MSE等。 本发明实施例根据信道质量动态选择分集保护发射模式或非分集保护发 射模式， 在保证分集技术可靠性同时， 有效提高了分集技术的频谱利用率。 实施例七
