具体实施方式
为了使本技术领域的人员更好地理解本发明方案,下面将结合本发明实施例中的附图,对本发明实施例中的技术方案进行清楚、完整地描述,显然,所描述的实施例仅仅是本发明一部分的实施例,而不是全部的实施例。基于本发明中的实施例,本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例,都应当属于本发明保护的范围。
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。应该理解这样使用的数据在适当情况下可以互换,以便这里描述的本发明的实施例能够以除了在这里图示或描述的那些以外的顺序实施。此外,术语“包括”和“具有”以及他们的 任何变形,意图在于覆盖不排他的包含,例如,包含了一系列步骤或单元的过程、方法、系统、产品或设备不必限于清楚地列出的那些步骤或单元,而是可包括没有清楚地列出的或对于这些过程、方法、产品或设备固有的其它步骤或单元。
实施例1
根据本发明实施例,提供了一种近距离通信的确定方法的方法实施例,需要说明的是,在附图的流程图示出的步骤可以在诸如一组计算机可执行指令的计算机系统中执行,并且,虽然在流程图中示出了逻辑顺序,但是在某些情况下,可以以不同于此处的顺序执行所示出或描述的步骤。
图1是根据本发明实施例的近距离通信的确定方法的流程图,如图1所示,该方法包括如下步骤:
步骤S102,确定第一信号与第二信号的相关值,其中,第一信号为第一终端在预定网络延时之前通过预定语音设备采集的环境音频信号,第二信号为第一终端在通信过程中接收到的第二终端输出的音频信号,相关值用于表示第一信号和第二信号之间的相似度;
可选的,在上述步骤中,相关值代表信号之间的相似度,可以通过对比信号波形的方法获取,相似度表示了信号之间的相关性,相似度越大,表示信号相关性越强。
需要说明的是,上述的环境音频是泛指指在网络延时前被采集到的音频信号,并不是仅限定背景音。
在上述步骤中,将求取出的相关值与预设的相关阈值做比对,若相关值大于预设的相关阈值,则信号之间相似度较大,存在近距离通信;若相关值小于预设的相关阈值,则信号之间的相似度较小,不存在近距离通信。
步骤S104,基于相关值确定第一终端与第二终端是否处于近距离通信的状态。
由上可知,在本发明实施例中,首先可以确定第一信号与第二信号的相关值,其中,第一信号为第一终端在预定网络延时之前通过预定语音设备采集的环境音频信号,第二信号为第一终端在通信过程中接收到的第二终端输出的音频信号,相关值用于表示第一信号和第二信号之间的相似度;最后可以基于相关值确定第一终端与第二终端是否处于近距离通信的状态。该方案中,将第一信号与第二信号的相关值与预设阈值作比对,根据比对结果就可以确定终端设备之间是否处于近距离通信,从而解决了相关技术中无法确定终端设备之间是否处于近距离通信的方案的技术问题。并且,将该方案应用在终端防啸叫处理上,可以较好地提升用户通信体验。
作为一种可选的实施例,在确定第一信号与第二信号的相关值之前,该方法还包括:在通信类型为第一通信类型的情况下,触发第一终端的信号接收部件开启,以接收第一信号,其中,信号接收部件为第一终端中用于接收信号的部件,第一通信类型为第二终端只开启上行通路并且第一终端只开启下行通路的通信类型;在通信类型为第二通信类型的情况下,接收第一信号与第二信号,其中,第二通信类型为第一终端和第二终端同时开启上行通路和下行通路的通信类型。
在上述可选的实施例中,在确定信号之间的相关值之前,需要首先建立第一终端与第二终端的通信连接,并且获取第一终端与第二终端的通信类型,若通信类型为单工通信,比如电视台与收音机之间的通信,则将上行MIC(即接收部件)打开,但是上行MIC的数据仅用作距离判断,并不会将信号发送至网络侧(例如基站等)。
作为一种可选的实施例,确定第一信号与第二信号的相关值,包括:获取相关窗口长度,其中,相关窗口长度是预先设定的时域范围;基于相关窗口长度分别截取第一信号和第二信号,得到第一目标信号和第二目标信号;获取第一目标信号和第二目标信号的相关值。
在上述可选的实施例中,相关窗口长度是实验前用户自定义的通信时域范围值,通过相关窗口长度可以在一段无限长的通信传输中截取第一信号与第二信号,方便后续对信号之间相关值求取的处理。
作为一种可选的实施例,获取第一目标信号和第二目标信号的相关值,至少包括:获取第一目标信号和第二目标信号的波形数据信息;将波形数据信息基于相关窗口长度做平移处理;将平移后的波形数据信息依次做位移处理,获取数组;基于数组确定第一目标信号和第二目标信号的相关值。
在上述可选的实施例中,确定信号之间的相关值,也即计算信号之间的相似度,可以首先将两个信号基于相关窗口长度进行不断平移,并在两个信号接触对齐的时候开始进行对应的相乘,并将所有对应的值进行相加,随着不断平移的同时进行不断计算,当信号平移至不接触时,会得到一个相关值的数组,求取数组中的最大值,以得到两个信号的相关值,来代表两个信号之间的相似度。
进一步地,通过相关窗口长度获取目标信号后,还可以通过计算第一目标信号与第二目标信号的相关系数来得到相关值。需要说明的是,确定第一信号与第二信号的相关值的方法包括但不限于以上两个方法。
作为一种可选的实施例,基于相关值确定第一终端与第二终端是否处于近距离通信的状态,包括:在相关值大于预设相关阈值的情况下,确定第一终端与第二终端处 于近距离通信的状态;在相关值不大于预设相关阈值的情况下,确定第一终端与第二终端没有处于近距离通信的状态。
作为一种可选的实施例,基于比对结果确定第一终端与第二终端是否为近距离通信,包括:在比对结果为相关值大于预设相关阈值的情况下,确定第一终端与第二终端为近距离通信;在比对结果为相关值不大于预设相关阈值的情况下,确定第一终端与第二终端不为近距离通信。
进一步地,当求取上述数组中的最大值后,将其看作信号之间的相关值,将其与预设的相关阈值做比对,若相关值大于预设的相关阈值,则说明信号之间相似度较大,存在近距离通信;若相关值不大于预设的相关阈值,则说明信号之间相似度较小,不存在近距离通信。
作为一种可选的实施例,在确定第一终端与第二终端为近距离通信之后,该方法还包括:在第一终端与第二终端之间的通信类型为第一通信类型的情况下,则调整第一终端与第二终端的信号功率,以确保第二终端的信号输出强度;在第一终端与第二终端之间的通信类型为第二通信类型的情况下,则调整第一终端的信号功率,以确保第二终端的信号输出强度。
在上述可选的实施例中,在判断终端之间存在近距离通信后,可以通过降低接收终端的下行增益的方式来防止出现啸叫现象。另外,还可以根据不同的通信类型对终端之间的信号进行人为改善,来减缓啸叫现象可能带来的负面作用。比如,当通信类型为单工通信(即第一通信类型)时,可以调整第一终端与第二终端之间的收发信号功率,以改善通话质量,来提高用户通信体验。另外,像专网收发之间直接通信的两个终端,还可以通过降低收发信号功率来达到降低功耗的技术效果。
作为一种可选的实施例,在基于相关值确定第一终端与第二终端是否处于近距离通信的状态之后,该方法还包括:保存并更新预定网络延时,其中,预定网络延时为第一终端与第二终端之间所需的通信时长。
需要说明的是,当判断结果为存在近距离通信后,可以保存当前的终端之间的通信网络延迟,用作后续相关值比对参考。
图2是根据本发明实施例的近距离通话时接收端信号的示意图,如图2所示,图2中最上行代表降噪处理的降噪模块信号,图2中最下行代表第一终端接收到的近端信号(即第一信号),左数第一个波形为近端信号,即第一终端接收到的初始信号,当近距离通话时,近端信号早于远端信号,需要说明的是,第一终端接收到的初始信号是指MIC采集的环境音,因为两个终端是近距离,所以第二终端发送的语音第一终端 可以直接通过MIC采集到,第二终端通过网络发送给第一终端的会有延时,因此比MIC直接采集到的信号晚,图2中中间行代表第一终端接收的远端信号(即第二信号),即初始信号发送给第二终端,第二终端将接收到的信号播放并且信号被第一终端重新接收到的信号,进一步地,中间行是第二终端发送给第一终端的信号。(是第一终端通过网络侧接收的信号)。如图2中最上行中第一段信号存在,也即降噪模块并没有对第一终端的初始输入信号(也即最开始输入的信号,第一信号)进行处理,而后续的对应于图2中最下行的左数第二段信号的降噪模块信号被消除掉了,也即该部分信号为远端信号被第一终端接收后由第一终端的扬声器播放后又被第一终端的麦克风所采集,也就是回声信号,该信号会影响通话质量,干扰实验流畅性,所以降噪模块将其消除。
需要说明的是,在本发明实施例中,消除模块选用的ECNS为信号实施消除回声信号的操作,ECNS(回声消除噪声抑制)上行输出表示上行DSP(数字信号处理)算法链路中经ECNS模块处理后的上行输出信号。
图3是根据本发明实施例的优选的近距离通信的确定方法的流程图,如图3所示,首先通话建立,判断是否为单工通信,若为单工通信,则其中的接收端开启mic,但仅用于收发距离检测,不发送至网络侧,接着预设初始网络延时(例如480ms),将接收的远端信号与设定网络延时之前的近端mic(即麦克风,上行信号)做相关,相关窗口长度定义(例如300ms),如果相关值大,则存在近距离通信,同时将校准的网络延时值保存,用作后续相关比较。再根据通信类型做具体执行,其中,如果是近距离双工通信,接收端的下行增益做降增益处理,保证组呼上行信号强度;如果是近距离单工通信,降低接收端的下行增益,并调整收发信号功率,来防止发生啸叫现象。
由上可知,在本发明实施例中,远距离通信情况下,收发终端mic采集的信号不同,没有相关性;但是近距离通信情况下,由于收发终端所处环境相同,收发终端的mic均可以采集到相同信号,本发明提供的实施例利用这一点,提出一种通信收发近距离检测的方法,用于判断是否是近距离通话,可以用作防啸叫处理,提升了用户通信体验,提高了通信的质量。
