具体实施方式
下文中将参考附图并结合实施例来详细说明本发明。需要说明的是,在不冲突的情况下,本发明中的实施例及实施例中的特征可以相互组合。
需要说明的是,本发明的说明书和权利要求书及上述附图中的术语“第一”、“第二”等是用于区别类似的对象,而不必用于描述特定的顺序或先后次序。
实施例1
本实施例提供的一种干扰模拟系统,设置于发送端,图1是根据本发明实施例提供的干扰模拟系统的功能示意图,如图1所示,该系统包括:
配置单元102,配置为根据干扰模型配置干扰参数,其中,干扰模型根据预设的干扰场景生成;
模拟单元104,配置为获取干扰参数,并根据干扰参数生成干扰信息;模拟单元还配置为,根据干扰信息在发送端模拟干扰场景。
需要进一步说明的是,上述发送端通常为基站或终端。上述配置单元与模拟单元均设置于无线通信系统的发送端,如基站侧,其中,配置单元可以集成在无线通信系统的自有后台中,即将无线通信系统的后台配置或监控模块中通过软件设置,以实现本实施例中的配置单元的功能。
上述干扰模型用于指示根据干扰场景而构造的模型,通常而言,干扰模型中包含多项配置参数或配置命令,用于形容对应的干扰场景可能对数据的影响。上述干扰模型的构造过程可以由本实施例中的干扰模拟系统实现,即指示配置单元根据需要模拟的干扰场景实时构造干扰模型,或指示配置单元预先根据不同的干扰场景构造不同的干扰模型,并存储在配置单元中,在实施干扰模拟的过程中读取需模拟的干扰场景对应的干扰模型即可;此外,上述干扰模型的构造也可以由非本实施例中的相关系统或单元得以实现,例如,由操作人员在PC端根据干扰场景生成干扰模型,并将该模型导入至配置单元中;本发明对上述干扰模型的构造时间以及过程不作限定。
与此同时,上述配置单元中,根据干扰模型配置干扰参数即指示根据干扰模型中设置的配置参数或配置命令,获取用于模拟干扰场景的干扰参数;该干扰参数可以直接读取干扰模型中的全部配置参数,也可以根据实际的干扰场景的模拟需求,对干扰模型中的配置参数或配置命令进行二次配置。例如,根据所需模拟的干扰场景的功能,在干扰模型的基础上选择部分配置参数以形成干扰参数,进而模拟干扰模型指示的干扰场景中的某一具体功能;或者,在干扰模型的基础上添加部分参数以形成干扰参数,进而模拟干扰模型所指示的干扰场景的扩展场景。
需要进一步说明的是,本实施例中的发送端在干扰模拟系统工作的过程中,仍保持正 常的工作流程,具体而言,发送端在上述干扰模拟的过程中,指示发送链路按照正常的系统处理流程,处理发送端的调度单元下发的调度配置,并产生对应的频域单元、时域单元处理后的数据,以发送至接收端。与此同时,模拟单元在获取上述配置单元配置的干扰参数后,即可根据干扰参数进一步生成干扰信息。上述模拟单元根据干扰信息在发送端模拟对应的干扰场景,即指示模拟单元在发送端根据干扰信息进行干扰的模拟,具体而言,可由模拟单元将干扰信息发送至发送端不同阶段处理的数据中,如上述调度处理、时域或频域处理中的数据,以形成干扰受损的数据后再发送至接收端,进而实现在发送端进行干扰模拟。
通过本实施例中的干扰模拟系统,由于设置在发送端的配置单元可根据干扰模型配置干扰参数,其中,干扰模型根据预设的干扰场景生成;并且,模拟单元可获取干扰参数,并根据干扰参数生成干扰信息,进而根据干扰信息在发送端模拟干扰场景。因此,本实施例中的干扰模拟系统可以至少在一定程度上解决在一些情形中无法高效模拟信道对数据的干扰的问题,以达到显著提高干扰模拟的实现效率的效果。
相较于一些情形,在无线信道实现对干扰的模拟,本实施例中的干扰模拟系统在发送端即实现对干扰的模拟,因此,在干扰模拟过程中本实施例中的干扰模拟系统一方面可针对性的对发送至目标接收端的数据进行干扰模拟,而无需对整个无线信道造成干扰,故不会影响现网系统的运行,从而降低模拟测试过程中的运营成本,并提高了实施效率;另一方面,由于上述干扰模拟的过程中已在发送端实现了干扰模拟,因此,无线信道中不需要增加真实的干扰终端或者干扰源即可完成干扰的模拟,以完成对相应产品的抗干扰能力的测试以及系统的干扰协调处理机制的验证,从而令产品的功能交付流程得以显著简化。此外,由于仅需在发送端进行干扰模拟,因此测试人员在操作过程中即可在基站所在位置,或远程操作基站自动实现上述干扰模拟,而无需在外场环境进行测试,从而减少了对应的人力物力成本,并进一步显著提高了实施的效率。
与此同时,本实施例中的干扰模拟系统基于根据干扰场景构造的干扰模型以及对应的干扰参数得以实现,而干扰模型可以根据实际需求不断的进行丰富,且干扰模型可在不同的协议版本处理链路之间进行移植,故本实施例中的干扰模拟系统还具有良好的扩展性;并且,在实际干扰模拟的过程中,本实施例中的干扰模拟系统还可根据实际需求实时配置干扰参数,以使得干扰模拟的灵活性得以显著改善。
在一实施例中,模拟单元104还配置为:
将干扰信息叠加至发送端的时域数据和/或频域数据中以模拟干扰场景。
需要进一步说明的是,上述干扰信息的叠加即指示模拟单元将干扰信息发送至发送端的时域处理单元所产生的时域数据和/或频域处理单元所产生的频域数据中,实际干扰模拟过程中,干扰信息的叠加对象取决于需要模拟的干扰场景。
在一实施例中,模拟单元104还配置为:
将干扰信息按照预设权重叠加至发送端的时域数据和/或频域数据中以模拟干扰场景;和/或,
将干扰信息叠加至发送端在预设周期内的时域数据和/或频域数据中以模拟干扰场景。
在一实施例中,系统还包括:
第一调度单元106,配置为获取干扰参数,并将干扰参数发送至模拟单元;第一调度单元106还配置为,处理发送端的调度数据,其中,调度数据用于形成时域数据以及频域数据。
需要进一步说明的是,上述第一调度单元发送端的调度数据,即指示第一调度单元为无线通信系统的自有模块,即第一调度单元集成在无线通信系统中,并通过软件设置,以实现本实施例中的第一调度单元对应的获取干扰参数,并将干扰参数发送至模拟单元的功能。图2是根据本发明实施例提供的干扰模拟系统的功能示意图(二),上述第一调度单元106的设置如图2所示。
在一实施例中,干扰场景包括以下至少之一:
时偏干扰场景、频偏干扰场景、频域子带间干扰场景、频率选择性干扰场景、符号间干扰场景。
为进一步说明本实施例中的干扰模拟系统的工作方式,以下通过多组具体示例,以说明本实施例中的干扰模拟系统对不同的干扰场景进行模拟的流程。
具体示例一:
本具体示例中的干扰场景为发送端频域干扰;具体而言,无线系统中,不同用户终端间由于频域资源分配冲突,或者在切换缓冲区不同终端用户的频域资源分配有重叠等原因产生频域干扰是常见现象。本具体示例中对上述发送端频域干扰进行模拟的过程如下:
S1、配置单元根据频域干扰模型配置对应的干扰参数,具体为,频域资源重叠比例参数、频域干扰功率幅度等;
S2、第一调度单元获取正常系统处理时的频域资源分配;
S3、第一调度单元将正常系统处理时的频域资源分配,以及上述干扰参数中的频域资源重叠比例参数、频域干扰功率幅度等发送至模拟单元;
S4、模拟单元根据上述正常调度的频域资源以及频域资源重叠比例参数、频域干扰功率幅度等产生干扰信息,本具体示例中即为频域资源重叠部分的干扰频域数据;
S5、第一调度单元进行正常通信的频域资源调度处理,并产生正常处理的频域数据;
S6、发送端正常处理产生的频域数据与干扰模拟单元产生的干扰频域数据加权叠加处理,以对频域数据进行干扰模拟;
S7、经过干扰模拟处理后的频域数据经过后续处理后通过射频发送出去,并经过空间无线信道到达接收端,接收端接收到的数据即为含有频域干扰信息的数据。
本具体示例S3与S4中,干扰参数包括但不限于上述频域资源重叠比例参数、频域干 扰功率幅度;S6中,干扰频域数据和正常数据的加权叠加,可以在频域内按照RE、PRB等对象施加不同的权值,也可以灵活选择是对所有频域符号施加相同的干扰,还是仅对某些符号施加干扰,施加干扰的周期也可以通过后台进行配置。
具体示例二
本具体示例中的干扰场景为5G-ATG发送端时域高斯白噪声干扰,具体而言,在5G地空互联系统中,由于超大的覆盖半径,发送端数据经过长距离传输,信号被干扰衰减很大;因此,作为终端设备的5G-ATG在商用部署前都要经过外场环境的干扰测试;其中。ATG终端发送的数据经过空口和无线信道,被空间长距离传输产生的高斯白噪声干扰是较常见的干扰场景。在该干扰场景下,发送端的时域样点数据会被随机的噪声样点数据叠加干扰。图3是根据本发明具体示例提供的发送端时域高斯白噪声干扰模拟示意图,如图3所示,本具体示例中对上述5G-ATG发送端时域高斯白噪声干扰进行模拟的过程如下:
S1、配置单元根据5G-ATG发送端时域高斯白噪声干扰对应的干扰模型配置对应的干扰参数,具体为,噪声幅度参数、噪声随机函数配置、信号传输距离等;
S2、第一调度单元将上述干扰参数配置给模拟单元;
S3、模拟单元根据干扰参数产生随机噪声样点数据;
S4、第一调度单元进行正常通信的调度处理,发送端正常处理产生的时域数据与模拟单元产生的随机噪声样点数据叠加处理;
S5、经过噪声模拟处理后的时域数据经过射频发送出去;
S6、上述ATG发送端天线口发送出去的数据经过空间传输,到达接收端后就是含有高斯噪声干扰信息的数据,接收端对数据进行接收处理即可。
在步骤S3、S4中,还可以在随机噪声样点中控制噪声产生的时机,可以对全部的时域符号加载噪声干扰,也可以仅对某些调度周期内的时域符号加载噪声干扰,或者针对某一调度周期内某些符号加载噪声干扰,噪声的生成和加载可以灵活控制,已模拟测试更多的干扰过程。上述的高斯噪声干扰也可以由其他噪声模型来替换,只需在配置单元中增加对应的模型实现即可。
具体示例三
本具体示例中的干扰场景为5G-ATG基站间信号干扰,具体而言,在5G地空互联系统中,由于超大的覆盖半径,基站发射功率很大,因此会产生一种时分双工(Time Division Duplexing,TDD)基站间干扰的场景。图4是根据本发明具体示例提供的5G-ATG基站间信号干扰场景示意图,如图4所示,两条红线之间,远端基站发送的信号有部分与被干扰基站的接收时刻对齐,此时接入被干扰基站的5G-ATG终端发送给被干扰基站的数据会与远端基站发送的干扰数据一起叠加进入被干扰基站的接收时隙,会导致被干扰基站接收的5G-ATG终端发送数据被干扰。本具体示例中对上述5G-ATG基站间信号干扰进行模拟的过程如下:
S1、ATG终端的配置单元根据5G-ATG基站间信号干扰模型配置干扰参数,具体为,基站DwPTS部分符号发送的信号类型、相关参数,小区距离等;
S2、ATG终端的第一调度单元将上述干扰参数发给模拟单元,模拟单元根据干扰参数产生干扰信息;
S3、上述ATG终端与被干扰5G基站建立正常无线数据连接;第一调度处理单元正常调度被干扰基站下发给终端的调度请求;ATG终端正常处理调度数据;
S4、模拟单元在终端相应的发送时刻,将产生的远端基站的干扰信息与终端正常处理产生的时域数据对齐,并考虑远端基站的距离等,以加权方式与正常发送端数据叠加;
S5、经过噪声模拟处理后的时域数据经过射频发送出去;
S6、上述ATG发送端天线口发送出去的数据经过无线信道传输,基站接收后就是含有远端基站发送的干扰信息的数据,基站接收端对数据进行接收处理即可。
实施例2
本实施例提供一种干扰测试系统,包括实施例1中所述的干扰模拟系统,图5是根据本发明实施例提供的干扰测试系统的功能示意图,如图5所示,本实施例中的干扰测试系统还包括:
第二调度单元108,设置在接收端,第二调度单元配置为,接收发送端在模拟干扰场景的情形下发送的数据,并对于数据进行测量以获取干扰测试结果。
需要进一步说明的是,上述接收端与发送端对应,例如,发送端为基站,接收端为终端,或者,发送端为终端,接收端为基站。上述第二调度单元与第一调度单元相对应,即第一调度单元为设置在发送端中的调度单元,第二调度单元即为设置在接收端中的调度单元。本实施例中,在干扰模拟系统在发送端实现干扰模拟的基础上,接收端通过无线信道所接收到的数据即为干扰受损后的数据,因此,通过第二调度单元对于接收端接收的数据进行测量,即可获取数据的干扰测试结果,进而完成对于设备接收性能或抗干扰能力等的测试。
第二调度单元获取干扰测试结果后,即可将该干扰测试结果反馈至后台,例如,发送端为基站时,第二调度单元可将干扰测试结果直接反馈至配置单元,发送端为终端时,第二调度单元可将干扰测试结果反馈至基站侧的后台配置或监控单元。图6是根据本发明实施例提供的干扰测试系统的工作示意图,本实施例中的干扰测试系统的工作方式如图6所示。
通过本实施例中的干扰测试系统,由于设置在发送端的配置单元可根据干扰模型配置干扰参数,其中,干扰模型根据预设的干扰场景生成;并且,模拟单元可获取干扰参数,并根据干扰参数生成干扰信息,进而根据干扰信息在发送端模拟干扰场景;同时,设置在接收端的第二调度单元可接收发送端在模拟干扰场景的情形下发送的数据,并对于数据进行测量以获取干扰测试结果;因此,本实施例中的干扰测试系统可以至少在一定程度上解 决在一些情形中无法高效模拟信道对数据的干扰的问题,以达到显著提高干扰模拟的实现效率的效果,并进一步完成对抗干扰能力等性能的测试。
本实施例中所包含的干扰模拟系统的其余技术方案以及技术效果均与实施例1中的干扰模拟系统相对应,故在此不再赘述。
实施例3
本实施例提供了一种干扰模拟方法,应用于发送端,图7是根据本发明实施例提供的干扰模拟方法的流程图,如图7所示,本实施例中的干扰模拟方法包括:
S302,根据预设的干扰场景生成干扰模型,并根据干扰模型配置干扰参数;
S304,根据干扰参数生成干扰信息,并根据干扰信息在发送端模拟干扰场景。
需要进一步说明的是,上述发送端通常为基站或终端。上述步骤S302中,干扰模型用于指示根据干扰场景而构造的模型,通常而言,干扰模型中包含多项配置参数或配置命令,用于形容对应的干扰场景可能对数据的影响。上述干扰模型的构造过程可以在干扰模拟的过程中实时进行,即根据需要模拟的干扰场景实时构造干扰模型,或预先根据不同的干扰场景构造不同的干扰模型,并存储在发送端的相关系统或单元中,在实施干扰模拟的过程中读取需模拟的干扰场景对应的干扰模型即可;此外,上述干扰模型的构造也可以由用以配置干扰参数的单元,如配置单元实现,也可由独立于本实施例中的干扰模拟方法的相关系统或单元实现,例如,由操作人员在PC端根据干扰场景生成干扰模型,并将该模型存储在发送端的相关系统或单元中;本发明对上述干扰模型的构造时间以及过程不作限定。
与此同时,上述步骤S302中,根据干扰模型配置干扰参数即指示根据干扰模型中设置的配置参数或配置命令,获取用于模拟干扰场景的干扰参数;该干扰参数可以直接读取干扰模型中的全部配置参数,也可以根据实际的干扰场景的模拟需求,对干扰模型中的配置参数或配置命令进行二次配置。例如,根据所需模拟的干扰场景的功能,在干扰模型的基础上选择部分配置参数以形成干扰参数,进而模拟干扰模型指示的干扰场景中的某一具体功能;或者,在干扰模型的基础上添加部分参数以形成干扰参数,进而模拟干扰模型所指示的干扰场景的扩展场景。
上述步骤S302可由发送端得以实现,具体而言,在无线通信系统的后台配置或监控模块中通过软件设置,以实现本实施例中的步骤S302的操作。
需要进一步说明的是,本实施例中的发送端在干扰模拟方法工作的过程中,仍保持正常的工作流程,具体而言,发送端在上述干扰模拟的过程中,指示发送链路按照正常的系统处理流程,处理发送端的调度单元下发的调度配置,并产生对应的频域单元、时域单元处理后的数据,以发送至接收端。与此同时,步骤S304可根据生成的干扰信息在发送端模拟对应的干扰场景,即在发送端根据干扰信息进行干扰的模拟,具体而言,可将干扰信息发送至发送端不同阶段处理的数据中,如上述调度处理、时域或频域处理中的数据,以 形成干扰受损的数据后再发送至接收端,进而实现在发送端进行干扰模拟。
通过本实施例中的干扰模拟方法,由于可根据预设的干扰场景生成干扰模型,并根据干扰模型配置干扰参数;同时,还可根据干扰参数生成干扰信息,进而根据干扰信息在发送端模拟干扰场景。因此,本实施例中的干扰模拟方法可以至少在一定程度上解决在一些情形中无法高效模拟信道对数据的干扰的问题,以达到显著提高干扰模拟的实现效率的效果。
相较于一些情形,在无线信道实现对干扰的模拟,本实施例中的干扰模拟方法在发送端即实现对干扰的模拟,因此,在干扰模拟过程中本实施例中的干扰模拟方法一方面可针对性的对发送至目标接收端的数据进行干扰模拟,而无需对整个无线信道造成干扰,故不会影响现网系统的运行,从而降低模拟测试过程中的运营成本,并提高了实施效率;另一方面,由于上述干扰模拟的过程中已在发送端实现了干扰模拟,因此,无线信道中不需要增加真实的干扰终端或者干扰源即可完成干扰的模拟,以完成对相应产品的抗干扰能力的测试以及系统的干扰协调处理机制的验证,从而令产品的功能交付流程得以显著简化。此外,由于仅需在发送端进行干扰模拟,因此测试人员在操作过程中即可在基站所在位置,或远程操作基站自动实现上述干扰模拟,而无需在外场环境进行测试,从而减少了对应的人力物力成本,并进一步显著提高了实施的效率。
与此同时,本实施例中的干扰模拟方法基于根据干扰场景构造的干扰模型以及对应的干扰参数得以实现,而干扰模型可以根据实际需求不断的进行丰富,且干扰模型可在不同的协议版本处理链路之间进行移植,故本实施例中的干扰模拟系统还具有良好的扩展性;并且,在实际干扰模拟的过程中,本实施例中的干扰模拟方法还可根据实际需求实时配置干扰参数,以使得干扰模拟的灵活性得以显著改善。
在一实施例中,上述步骤S304中,根据干扰信息在发送端模拟干扰场景,包括:
将干扰信息叠加至发送端的时域数据和/或频域数据中以模拟干扰场景。
需要进一步说明的是,上述干扰信息的叠加即指示将干扰信息发送至发送端的时域处理单元所产生的时域数据和/或频域处理单元所产生的频域数据中,实际干扰模拟过程中,干扰信息的叠加对象取决于需要模拟的干扰场景。
在一实施例中,上述将干扰信息叠加至发送端的时域数据和/或频域数据中以模拟干扰场景,还包括:
将干扰信息按照预设权重叠加至发送端的时域数据和/或频域数据中以模拟干扰场景;和/或,
将干扰信息叠加至发送端在预设周期内的时域数据和/或频域数据中以模拟干扰场景。
在一实施例中,干扰场景包括以下至少之一:
时偏干扰场景、频偏干扰场景、频域子带间干扰场景、频率选择性干扰场景、符号间干扰场景。

上述步骤S306中,获取干扰测试结果后,即可将该干扰测试结果反馈至后台,例如,发送端为基站时,可将干扰测试结果直接反馈至配置单元,发送端为终端时,可将干扰测试结果反馈至基站侧的后台配置或监控单元。
