具体实施方式
为了使本申请的目的、技术方法及优点更加清楚明白，以下结合附图及实施例，对本申请进行进一步详细说明。应当理解，此处所描述的实施例仅用以解释本申请，并不用于限定本申请。
需要说明的是，虽然在流程图中示出了逻辑顺序，但是在某些情况下，可以以不同于流程图中的顺序执行所示出或描述的步骤。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。
本申请提供了一种信号检测方法及信号检测设备、计算机可读存储介质。其中一个实施 例的信号检测设备，包括：信号处理组件，被配置为接收包括多个数据流的初始信号，并对初始信号进行预处理得到多个数据信号以及每个数据信号对应的信道参数；信号分组组件，与信号处理组件的输出端连接，被配置为接收多个数据信号以及每个数据信号对应的信道参数，并根据多个数据信号的信道参数对多个数据信号进行分组；信号检测组件，与信号分组组件的输出端连接，被配置为接收分组后的多个数据信号，并对分组后的多个数据信号进行分组检测，得到对于所有数据信号的分组检测结果。该实施例中，通过信号处理组件预处理初始信号而得到多个数据信号以及每个数据信号对应的信道参数，以便于信号分组组件根据信道参数将待检测的多个数据信号进行分组，并基于信号检测组件对分组后的各个数据信号进行分组检测，由于分组后只需对各个分组内数量相对更少的数据信号分别进行检测，因此可以将复杂的信号检测流程拆分为各个分组内相对简单的信号检测流程，实现了信号检测复杂度的降低，从而可以弥补相关方法中的技术空白。
下面结合附图，对本申请实施例作进一步阐述。
如图1所示，图1是本申请一个实施例提供的信号检测设备100的示意图，该信号检测设备100包括但不限于有信号分组组件110、信号检测组件120和信号处理组件130。
其中，信号分组组件110分别与信号检测组件120和信号处理组件130连接；
信号处理组件130，被配置为接收包括多个数据流的初始信号，并对初始信号进行预处理得到多个数据信号以及每个数据信号对应的信道参数；
信号分组组件110，被配置为接收多个数据信号以及每个数据信号对应的信道参数，并根据多个数据信号的信道参数对多个数据信号进行分组；
信号检测组件120，被配置为接收分组后的多个数据信号，并对分组后的多个数据信号进行分组检测，得到对于所有数据信号的分组检测结果。
通过信号处理组件130预处理初始信号而得到多个数据信号以及每个数据信号对应的信道参数，以便于信号分组组件110根据信道参数将待检测的多个数据信号进行分组，并基于信号检测组件120对分组后的各个数据信号进行分组检测，由于分组后只需对各个分组内数量相对更少的数据信号分别进行检测，因此可以将复杂的信号检测流程拆分为各个分组内相对简单的信号检测流程，实现了信号检测复杂度的降低，从而可以弥补相关方法中的技术空白。
在一实施例中，如图2所示，信号检测设备100还包括：信号合并检测组件140，与信号检测组件120的输出端连接，被配置为接收对于所有数据信号的分组检测结果，并对分组检测结果进行干扰消除处理，得到对于所有数据信号的输出检测结果；基于信号合并检测组件140对分组检测结果进行干扰消除处理得到输出检测结果，能够提高信号检测性能，改善分组检测可能带来的误差影响以满足检测需求。
在一实施例中，信号处理组件可以包括但不限于：
第一信号处理组件，被配置为接收包括多个数据流的初始信号并对初始信号进行前端处理，得到多个第一处理信号；
第二信号处理组件，分别与第一信号处理组件和信号分组组件连接，被配置为接收由第一信号处理组件发送的所有第一处理信号，并对所有第一处理信号进行频偏修正和频域处理得到所有携带信道参数的数据信号，向信号分组组件发送所有数据信号和每个数据信号对应的信道参数。
通过第一信号处理组件和第二信号处理组件的配合，可以实现获取初始的无线信号并对该无线信号进行预处理而得到待检测的数据信号和其对应的信道参数，以便信号分组组件能够获取到每个数据信号的信道参数并进行后续相关检测操作，也就是说，第一信号处理组件和第二信号处理组件可以配合起到预处理初始数据信号而确定每个数据信号的信道参数的作用。
其中，第一信号处理组件可以作为射频前端从空口接收初始的无线信号并对其进行前端处理，该前端处理包括但不限于为：AGC放大、频谱搬移以及滤波处理等，通过第一信号处理组件的处理得到第一处理信号，使得第一处理信号可成为能够被后端处理的信号。
其中，第二信号处理组件可以包括但不限于信号输入频偏补偿元件、快速傅立叶变换(Fast Fourier Transform，FFT)模块以及长训练字段(Long Training Field，LTF)解析器，信号输入频偏补偿元件可以对第一处理信号进行频偏修正，以降低频偏带来的子载波间干扰，而后将处理得到的信号送入到FFT模块转换至频域进行处理，在频域进行处理时将LTF部分和其余数据部分进行分离，再将LTF部分送入LTF解析器进行信道估计得到信道矩阵H，这样就能够得到携带信道参数的数据信号，以便于将每个数据信号的信道参数向信号分组组件发送。在一实施例中，信号处理组件、信号分组组件、信号检测组件和信号合并检测组件可以被集成地设置在信号检测设备中，也可以从信号检测设备中被分别地拆分出来，或者本领域技术人员也可以自行选择各个组件之间的配合实现方式，此处并未限定。
在一实施例中，信号检测设备可以但不限于应用于采用第7代WIFI协议且基于多输入多输出MIMO技术进行通信的通信系统，可适配于同时处理相对较多(例如，空间流数量大于4)空间流数据的第7代WIFI协议下的AP，其中，本实施例中的“空间流数据”与下述各实施例中的“空间流”、“数据信号”实质表达相同含义，即指的均是待检测的信号，为免产生混淆，特此说明。
在一实施例中，信号检测设备的应用场景可以但不限于为站点STA密集接入场景，如图3所示，图3是本申请一个实施例提供的信号检测设备的应用场景示意图，此时图3中的一个AP需要同时处理多个分别来自各个终端(即图3中所示的终端1、终端2…终端n)的空间流，即该AP采用第7代WIFI协议所允许的MU-MIMO技术进行空间流接入直至AP需要同时检测的流数达到16，此时信号检测设备可以根据预设策略对各个空间流进行分组处理，并在各个分组内进行检测得到分组检测结果，然后将分组检测结果送入后续模块进行处理，经过上述流程可以完成对接收信号的解耦。需要说明的是，本申请不仅可以应用于第7代WIFI协议密集接入多数据流检测场景中，还可以兼容之前的WIFI协议，不仅能够应用于WLAN领域的Single AP检测，还有可能被应用于WLAN领域的多AP的MIMO检测中，此处并未限定。
在一实施例中，图3中的终端可以但不限于为用户设备(User Equipment，UE)、用户单元、用户站、移动站、移动台、远方站、远程终端、移动设备、用户终端、无线通信设备、用户代理或用户装置等，且在具体应用场景中的呈现形式可以为不同的，也就是说，终端在不同应用场景中可以为不同的，此处并未限定。
在一实施例中，信号分组组件，被配置为根据获取到的多个数据信号的信道参数和预设的信道参数评分策略计算出每个数据信号对应的特征值，并从所有数据信号中将特征值处于同一预设范围内的若干数据信号划分到同一组中，也就是说，信号分组组件可以根据对多个 数据信号分别进行计算得到的相关特征值以实现准确分组，这样分组的方式是由评分值所主导，不会出现太多的错误分组或漏分组的情况，可以确保分组能够正常进行。
在一实施例中，信道参数可以包括多个类型，例如信干噪比(Signal to Interference plus Noise Ratio，SINR)、信噪比(Signal-Noise Ratio，SNR)以及信道矩阵等，此处不作限定，在计算多个数据信号的特征值时，可以从信道参数中选出一种或多种作为标准来进行计算；预设范围可以取为相近似的范围，即可以将特征值相近的若干数据信息划分到同一个组中，这说明分组结果的预设范围可以根据实际场景进行设置，此处并未限定；此外，基于本实施例的划分方式所划分得到的分组数和每个分组内的数据信号的个数可以不作限定。
在一实施例中，信道参数评分策略可以根据具体应用场景进行设置，此处并未限定。例如，信道参数评分策略可以包括但不限于如下至少之一：
当信道参数包括信干噪比，根据信干噪比的大小进行评分；
当信道参数包括信噪比，根据信噪比的大小进行评分；
当信道参数包括信道矩阵，根据信道矩阵的主对角元素进行评分；
当信道参数包括信道矩阵，根据信道矩阵的列二范数的大小进行评分；
当所述信道参数包括信号强度，根据信号强度的大小进行评分。
可以理解地是，信道参数还可以包括其他的类型，那么信道参数评分策略可以相应变化，不作限定，以下给出示例以说明信号分组组件的工作原理。
示例一：
采用分组器作为信号分组组件，分组器为一种根据一定规则或参数(例如，信道矩阵H或信号强度)对数据信号进行分组的装置，目的在于将工作环境的数据信号分在同一组中进行检测，其输入可以为信道矩阵H和待检测的数据信号，输出为经过分组调整的待检测的数据信号，以指示哪些数据信号在同一组内被送入后续的信号检测组件进行检测。
一种分组流程可以为：根据评分标准计算每条空间流的得分，将得分相近的空间流分到同一组中，其中，评分标准可以但不限于采用：SNR最优、信道矩阵的主对角元素占优、SINR最优、信道矩阵的列二范数最大以及接收信号强度最优等，可以选择后续检测中优先检测评分高的分组。
以采用SNR最优算法为例，存储得到信道矩阵H后，对信道矩阵H求逆得到再分别计算对应排序组内空间流的得分Score，计算方式为：
那么当前应当被检测的组为上述计算结果所对应的组
以采用主对角占优算法为例，对信道矩阵H按行进行分割每个行向量可以表示为此时本行的得分Score为：
此时，当前组内得分为应当被检测组为
在一实施例中，信号检测组件，可以但不限于被配置为根据分组结果对多个数据信号进行串行分组检测或并行分组检测，也就是说，信号检测组件可以采用单一分组检测器进行串行检测或者采用多个分组检测器进行并行检测，通过串行分组检测或并行分组检测可以确保对多个数据信号进行检测的精确度，至于具体采用串行分组检测或并行分组检测，可以根据实际情景进行选择设置，也就是说，通常而言，并行检测的效率更高但成本也相对更高，因此需要在具体场景中进行权衡选择相应的检测方式。
在一实施例中，信号检测组件，可以但不限于被配置为采用ZF检测算法、MMSE检测算法、最大似然检测算法、球形检测算法、串行干扰消除检测算法和并行干扰消除检测算法中的至少一种，对分组后的多个数据信号进行分组检测，以确保分组检测流程能够正常进行，即在算法的辅助下可以准确可靠地对分组后的多个数据信号进行分组检测，至于具体采用的算法可以根据具体场景进行选择设置，此处不作限定；其中，最大似然检测算法可以为多种类型，例如可以为正常状态下的，也可以为减状态下的等。
需要说明的是，上述ZF检测算法、MMSE检测算法、最大似然检测算法、球形检测算法、串行干扰消除检测算法和并行干扰消除检测算法为本领域技术人员所熟知，故此处不作赘述。
在一实施例中，由于在对各个数据信号进行分组检测以后，组与组之间可能存在组间干扰，那么为了消除这种组间干扰，信号合并检测组件可以但不限于被配置为采用如下至少之一的方式对分组检测结果进行干扰消除处理：

对分组检测结果进行并行干扰消除处理；
从分组检测结果中获取每个数据信号的信号检测结果，对所有信号检测结果进行串行干扰消除处理；
从分组检测结果中获取每个数据信号的信号检测结果，对所有信号检测结果进行并行干扰消除处理。
需要说明的是，在具体应用场景中，可以根据实际情况从上述各种干扰消除处理方式中选择合适的一种或多种进行干扰消除处理。
在一实施例中，对分组检测结果进行串行干扰消除处理，即部署以组为单位的组间串行干扰消除方式，有利于消除各个分组之间的串行干扰，或者对分组检测结果进行并行干扰消除处理，即部署以组为单位的组间并行干扰消除方式，有利于消除各个分组之间的并行干扰；从分组检测结果中获取每个数据信号的信号检测结果，对所有信号检测结果进行串行干扰消除处理，即部署以数据信号为单位的串行干扰消除方式，有利于消除各个分组之间的串行干扰，或者从分组检测结果中获取每个数据信号的信号检测结果，对所有信号检测结果进行并行干扰消除处理，即部署以数据信号为单位的并行干扰消除方式，有利于消除各个分组之间的并行干扰。
在一实施例中，信号合并检测组件还被配置为对输出检测结果进行多次迭代干扰消除处理，其中，下一次迭代干扰消除处理的输入为上一次迭代干扰消除处理对应的输出检测结果； 对输出检测结果进行迭代干扰消除处理，有利于以迭代的方式优化输出检测结果，即部署单个具有迭代结构的信号合并检测组件进行迭代干扰消除以获得更优的输出检测结果，例如，可以但不限于将本次迭代的输入设定为上一次迭代的输出检测结果，以此类推，当达到预设迭代次数或判定检测结果符合预设要求时，则可以停止迭代。
需要说明的是，串行干扰消除处理、并行干扰消除处理和迭代干扰消除处理的具体实现方式为本领域技术人员所熟知，故在此对其不作赘述。

本步骤中，对输出检测结果进行迭代干扰消除处理，有利于以迭代的方式优化输出检测结果，即部署单个具有迭代结构的信号合并检测组件进行迭代干扰消除以获得更优的输出检测结果，例如，可以但不限于将本次迭代的输入设定为上一次的输出检测结果，以此类推，当达到预设迭代次数或判定检测结果符合预设要求时，则可以停止迭代。
需要说明的是，由于本实施例中的步骤S140和步骤S150与上述信号检测设备的相关实施例属于同一发明构思，相互之间为完全对应的，区别仅在于方法与装置的客体不同，因此本实施例中的步骤S140和步骤S150的其他具体实施方式以及相关实施方式，可以参照上述实施例中的信号检测设备的相关实施例，为避免冗余，本实施例的步骤S140和步骤S150的其他具体实施方式以及相关实施方式在此不再赘述。
如图12所示，本申请的一个实施例，对步骤S120进行说明，步骤S120包括但不限于步骤S1201至S1202。
步骤S1201：控制信号分组组件根据多个数据信号的信道参数和预设的信道参数评分策略计算出每个数据信号对应的特征值；
步骤S1202：控制信号分组组件从所有数据信号中，将特征值处于同一预设范围内的若干数据信号划分到同一组中。
本步骤中，控制信号分组组件根据对多个数据信号分别进行计算得到的相关特征值以实现准确分组，这样分组的方式是由评分值所主导，不会出现太多的错误分组或漏分组的情况，可以确保分组能够正常进行。
在一实施例中，信道参数评分策略可以根据具体应用场景进行设置，此处并未限定。例如，信道参数评分策略可以包括但不限于如下至少之一：
当信道参数包括信干噪比，根据信干噪比的大小进行评分；
当信道参数包括信噪比，根据信噪比的大小进行评分；
当信道参数包括信道矩阵，根据信道矩阵的主对角元素进行评分；
当信道参数包括信道矩阵，根据信道矩阵的列二范数的大小进行评分；
当所述信道参数包括信号强度，根据信号强度的大小进行评分。
可以理解地是，信道参数还可以包括其他的类型，那么信道参数评分策略可以相应变化，不作限定。
需要说明的是，由于本实施例中的步骤S1201至S1202与上述信号检测设备的相关实施例属于同一发明构思，相互之间为完全对应的，区别仅在于方法与装置的客体不同，因此本实施例中的步骤S1201至S1202的其他具体实施方式以及相关实施方式，可以参照上述实施例中的信号检测设备的相关实施例，为避免冗余，本实施例的步骤S1201至S1202的其他具体实施方式以及相关实施方式在此不再赘述。
本申请的一个实施例，对步骤S130中的“控制信号检测组件对分组后的多个数据信号进行分组检测”进行说明，步骤S130包括但不限于步骤S131。
步骤S131：控制信号检测组件根据分组结果对多个数据信号进行串行分组检测或并行分组检测。
本步骤中，信号检测组件可以采用单一分组检测器进行串行检测或者采用多个分组检测器进行并行检测，通过串行分组检测或并行分组检测可以确保对多个数据信号进行检测的精确度，至于具体采用串行分组检测或并行分组检测，可以根据实际情景进行选择设置，也就是说，通常而言，并行检测的效率更高但成本也相对更高，因此需要在具体场景中进行权衡选择相应的检测方式。
需要说明的是，由于本实施例中的步骤S131与上述信号检测设备的相关实施例属于同一发明构思，相互之间为完全对应的，区别仅在于方法与装置的客体不同，因此本实施例中的步骤S131的其他具体实施方式以及相关实施方式，可以参照上述实施例中的信号检测设备的相关实施例，为避免冗余，本实施例的步骤S131的其他具体实施方式以及相关实施方式在此不再赘述。
如图13所示，本申请的一个实施例，对步骤S130中的“控制信号检测组件对分组后的多个数据信号进行分组检测”进行说明，步骤S130包括但不限于步骤S132。
步骤S132：控制信号检测组件采用迫零检测算法、最小均方误差检测算法、最大似然检测算法、球形检测算法、串行干扰消除检测算法和并行干扰消除检测算法中的至少一种，对分组后的多个数据信号进行分组检测。
本步骤中，采用算法检测的方式以确保分组检测流程能够正常进行，即在算法的辅助下可以准确可靠地对多个数据信号进行分组检测。
需要说明的是，由于本实施例中的步骤S132与上述信号检测设备的相关实施例属于同一发明构思，相互之间为完全对应的，区别仅在于方法与装置的客体不同，因此本实施例中的步骤S132的其他具体实施方式以及相关实施方式，可以参照上述实施例中的信号检测设备的相关实施例，为避免冗余，本实施例的步骤S132的其他具体实施方式以及相关实施方式在此不再赘述。
如图14所示，本申请的一个实施例，对步骤S110进行说明，步骤S110包括但不限于步骤S111至S113。
步骤S111：控制第一信号处理组件接收包括多个数据流的初始信号并对初始信号进行前端处理，得到多个第一处理信号；
步骤S112：控制第二信号处理组件接收由第一信号处理组件发送的所有第一处理信号， 并对所有第一处理信号进行频偏修正和频域处理得到所有携带信道参数的数据信号；
步骤S113：控制第二信号处理组件向信号分组组件发送所有数据信号和每个数据信号对应的信道参数。
本步骤中，通过控制第一信号处理组件和第二信号处理组件，可以实现获取初始的无线信号并对该无线信号进行预处理而得到待检测的数据信号和其对应的信道参数，以便信号分组组件能够获取到每个数据信号的信道参数并进行后续相关检测操作，也就是说，控制第一信号处理组件和第二信号处理组件以使其配合起到预处理初始数据信号而确定每个数据信号的信道参数的作用。
需要说明的是，由于本实施例中的步骤S111至S113与上述信号检测设备的相关实施例属于同一发明构思，相互之间为完全对应的，区别仅在于方法与装置的客体不同，因此本实施例中的步骤S111至S113的其他具体实施方式以及相关实施方式，可以参照上述实施例中的信号检测设备的相关实施例，为避免冗余，本实施例的步骤S111至S113的其他具体实施方式以及相关实施方式在此不再赘述。
另外，如图15所示，本申请的一个实施例还公开了一种信号检测设备200，包括：至少一个处理器210；至少一个存储器220，被配置为存储至少一个程序；当至少一个程序被至少一个处理器210执行时实现如前面任意实施例中的信号检测方法。
另外，本申请的一个实施例还公开了一种计算机可读存储介质，其中存储有计算机可执行指令，计算机可执行指令被配置为执行如前面任意实施例中的信号检测方法。
此外，本申请的一个实施例还公开了一种计算机程序产品，包括计算机程序或计算机指令，计算机程序或计算机指令存储在计算机可读存储介质中，计算机设备的处理器从计算机可读存储介质读取计算机程序或计算机指令，处理器执行计算机程序或计算机指令，使得计算机设备执行如前面任意实施例中的信号检测方法。
本申请实施例中，通过信号处理组件预处理初始信号而得到多个数据信号以及每个数据信号对应的信道参数，以便于信号分组组件根据信道参数将待检测的多个数据信号进行分组，并基于信号检测组件对分组后的各个数据信号进行分组检测，由于分组后只需对各个分组内数量相对更少的数据信号分别进行检测，因此可以将复杂的信号检测流程拆分为各个分组内相对简单的信号检测流程，实现了信号检测复杂度的降低，从而可以弥补相关方法中的技术空白。
本领域普通技术人员可以理解，上文中所公开方法中的全部或某些步骤、系统可以被实施为软件、固件、硬件及其适当的组合。某些物理组件或所有物理组件可以被实施为由处理器，如中央处理器、数字信号处理器或微处理器执行的软件，或者被实施为硬件，或者被实施为集成电路，如专用集成电路。这样的软件可以分布在计算机可读介质上，计算机可读介质可以包括计算机存储介质(或非暂时性介质)和通信介质(或暂时性介质)。如本领域普通技术人员公知的，术语计算机存储介质包括在用于存储信息(诸如计算机可读指令、数据结构、程序模块或其他数据)的任何方法或技术中实施的易失性和非易失性、可移除和不可移除介质。计算机存储介质包括但不限于RAM、ROM、EEPROM、闪存或其他存储器技术、CD-ROM、数字多功能盘(DVD)或其他光盘存储、磁盒、磁带、磁盘存储或其他磁存储装置、或者可以用于存储期望的信息并且可以被计算机访问的任何其他的介质。此外，本领域普通技术人员公知的是，通信介质通常包含计算机可读指令、数据结构、程序模块或者诸如 载波或其他传输机制之类的调制数据信号中的其他数据，并且可包括任何信息递送介质。
