If the standard deviation of the error vector magnitude is greater than the third standard deviation threshold, it can be considered that the discreteness of the channel estimation results of these N consecutive data packets is too high, resulting in poor channel quality.

技术领域
本申请属于通信技术领域，具体涉及一种信号的发送方法、装置及电子设备。
背景技术
随着电子技术的高速发展，手机、平板电脑、掌上电脑等电子设备越来越普及，已逐渐成为人们生活中不可或缺的一部分。目前无线局域网(Wireless Fidelity，WiFi)技术已经在电子设备中广泛采用，利用WiFi上网的方式受到越来越多用户的青睐。
通常，当电子设备检测到WiFi信号后，会以一定的发射功率将待传输的数据传给提供WiFi信号的WiFi路由设备。事实上，发射功率越大意味着较高的数据传输速率以及较高的通信质量，但发射功率越大同样需求更高的功耗。因此，如何兼顾电子设备的通信质量和功耗成为亟待解决的问题。
发明内容
本申请实施例的目的是提供一种信号的发送方法、装置及电子设备，能够解决在现有WiFi协议无法兼顾电子设备的通信质量和功耗的技术问题。

具体实施方式
下面将结合本申请实施例中的附图，对本申请实施例中的技术方案进行清楚地描述，显然，所描述的实施例是本申请一部分实施例，而不是全部的实施例。基于本申请中的实施例，本领域普通技术人员获得的所有其他实施例，都属于本申请保护的范围。
本申请的说明书和权利要求书中的术语“第一”、“第二”等是用于区别类似的对象，而不用于描述特定的顺序或先后次序。应该理解这样使用的术语在适当情况下可以互换，以便本申请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，且“第一”、“第二”等所区分的对象通常为一类，并不限定对象的个数，例如第一对象可以是一个，也可以是多个。此外，说明书以及权利要求中“和/或”表示所连接对象的至少其中之一，字符“/”，一般表示前后关联对象是一种“或”的关系。
为解决上述技术问题，本申请提供了一种信号的发送方法。下面结合附图，通过具体的实施例及其应用场景对本申请实施例提供的信号的发送方法进行详细地说明。
如图1所示，图1是本申请一个实施例提供的信号的发送方法的流程示意图，本申请实施例提供一种信号的发送方法，该方法可以包括：
S101，接收第二电子设备发送的第一WiFi信号；
在本实施例中，在无线局域网环境中，第二电子设备可以为WiFi路由设备，WiFi路由设备作为WiFi接入点，可以为周围的终端设备提供WiFi网络接入。终端设备可以连入该WiFi网络，然后第二电子设备和终端设备之间可以通过传输WiFi信号进行通信。其中，第一电子设备可以为连入第二电子设备提供的WiFi网络的终端设备。
S102，根据所述第一WiFi信号的质量参数确定第二WiFi信号中至少一个字段的目标发射功率，其中，所述第二WiFi信号为所述第一电子设备向所述第二电子设备发送的WiFi信号；
在本实施例中，WiFi网络下的终端设备和第二电子设备通常会以固定的默认功率进行WiFi信号的传输。在终端设备接收到第二电子设备按照默认功率发送的第一WiFi信号之后，可以对第一WiFi信号进行解析，得到第一WiFi信号的质量参数，质量参数能够表示第一WiFi信号对信号质量，并可以基于信号质量进一步评估终端设备和第二电子设备之间的网络环境。
如果质量参数反映的信号质量和网络环境较好，终端设备则可以按照默认功率进行第二WiFi信号的发射。
如果质量参数反映的信号质量和网络环境较差，则在终端设备向第二电子设备进行第二WiFi信号的发送时，如果终端设备仍然以默认功率进行第二WiFi信号的发射，将可能造成第二电子设备无法正确接收数据、数据传输速率降低以及网络延迟增加等问题。为了避免上述问题，需要根据质量参数重新确定第二WiFi信号的目标发射功率。
由于WiFi信号是由一系列数据包构成的，而每个数据包又都是由格式相同的多个字段构成的。因此，在重新确定第二WiFi信号的目标发射功率的过程中，可以重新确定第二WiFi信号整体的目标发射功率，也可以仅重新确定第二WiFi信号中数据包的部分字段的目标发射功率。
S103，以所述目标发射功率发送所述第二WiFi信号中至少一个字段。
本申请实施例中，在确定目标发射功率后，终端设备可以将目标发射功率设置为其当前运行的发射功率，使得终端设备在向第二电子设备进行通信时，可以按照目标发射功率来进行信号的传输，以目标发射功率发送第二WiFi信号中至少一个字段。终端设备还可以每间隔预设时间重新获取接收到的第一WiFi信号的质量参数，并基于质量参数更新目标发射功率，然后根据最新的目标发射功率对实际的发射功率进行动态调整，即将终端设备实际的发射功率更新为最新的目标发射功率。
在本申请中，可以接收第二电子设备发送的第一WiFi信号，并根据第一WiFi信号的质量参数，来调整第二WiFi信号中至少一个字段的发射功率。如此一来，由于信号的质量参数用于表征第一电子设备所在网络环境的通信质量，因此基于质量参数调整第一电子设备发射的信号中部分或全部字段的发射功率，可以通过对信号中各字段的发射功率的灵活调整，使得信号的发射功率和当前的网络环境相匹配，让第一电子设备在保证通信质量的情况下尽可能的降低功耗。
在一些实施例中，S102包括：
在所述质量参数满足第一条件的情况下，获取所述第一WiFi信号中至少一个数据包的数据状态；
根据所述数据状态将所述第二WiFi信号中的至少一个字段确定为第一字段；
根据所述数据状态确定所述第一字段的目标发射功率。
在本实施例中，可以通过对接收到的第一WiFi信号的WiFi帧头的解析，提取第一WiFi信号的质量参数。在获取第一WiFi信号的质量参数之后，如果第一WiFi信号的质量参数满足第一条件，则可以认为第一电子设备向第二电子设备发送的第二WiFi信号中可能存在需要功率突破的字段。则可以通过对第一WiFi信号中各数据包中包括的各字段进行解析，来确定数据包的信号调制参数，并通过信号调制参数获取数据包的数据状态，数据状态同样可以反应第一WiFi信号的通信情况，因此，可以基于数据包的数据状态确定第二WiFi信号中需要进行功率突破的字段，并将需要进行功率突破的至少一个字段确定为第一字段，然后根据数据状态确定第一字段的目标发射功率。其中，第一条件意味着质量参数小于用户提前设置的质量阈值，因此第一电子设备向第二电子设备发送的第二WiFi信号中存在需要功率突破的字段。
本实施例中，将第一WiFi信号的质量参数，和第一WiFi信号中数据包具体的数据状态进行结合，共同评估终端设备和第二电子设备之间的通信质量，并确定第二WiFi信号中需要调整发射功率的第一字段，并确定第一字段的目标发射功率，如此能够获得更准确的目标发射功率，使得目标发射功率更好的适配当前的网络环境。
在一些实施例中，所述质量参数包括信号强度和调制编码等级，所述获取所述第一WiFi信号中至少一个数据包的数据状态之前，还包括：
在所述信号强度小于信号强度阈值，且所述调制编码等级小于等级阈值的情况下，确定所述质量参数满足所述第一条件。
在本实施例中，第一WiFi信号的质量参数可以包括RSSI(Received Signal Strength Indicator，信号强度)和MCS等级(Modulation and Coding Scheme，调制编码等级)。
其中，RSSI是指接收到的第一WiFi信号的信号强度，信号强度可以用来评估设备之间的连接质量。较高的RSSI表示信号较强，较低的RSSI表示信号较弱。MCS等级表示使用的调制和编码方案的类型和参数，MCS等级可以和RSSI来共同评估第一WiFi信号的数据传输速率。
在本实施例中，可以首先检测第一WiFi信号对应的信号强度，然后将信号强度和预设的信号强度阈值进行比较，如果信号强度大于或等于信号强度阈值，可以认为终端设备和第二电子设备之间的通信质量较高，那么终端设备按照默认功率进行WiFi信号的发射即可。如果信号强度小于信号强度阈值，则可以进一步将调制编码等级和预设的等级阈值进行比较，如果调制编码等级小于等级阈值，则认为按照当前的调制编码方案，在当前的网络环境下进行信号传输的传输速率会比较慢，并可能会导致传输中断。
因此，终端设备不能按照默认功率进行第二WiFi信号的发送，终端设备可以根据数据状态在第二WiFi信号包括的多个字段中选择至少一个需要增大发射功率的第一字段，并重新确定第一字段的目标发射功率。
此外，如果信号强度大于或等于信号强度阈值，或者信号强度小于信号强度阈值且调制编码等级大于或等于等级阈值，终端设备可以按照默认功率进行信号的发射，并每间隔预设时间将信号强度和调制编码等级和对应的阈值进行比较，来重新评估网络环境，以确定是否需要重新确定第二WiFi信号的发射功率。
通过上述方式，可以通过第一WiFi信号的信号强度和调制编码等级来评估信号在终端设备和第二电子设备之间的通信质量，如果通信质量较低，则根据数据状态来确定第二WiFi信号中部分获全部字段的发射功率，从而使得第二WiFi信号的发射功率能够适配当前终端设备和第二电子设备之间的网络环境。
在一些实施例中，所述第一WiFi信号包括多个数据包，每个数据包包括短训练字段、长训练字段、信号字段以及数据字段中的至少一个，所述数据状态包括数据包的频率偏移值、信道估计结果以及各字段的误差向量幅度中的至少一个，
所述根据所述数据状态将所述第二WiFi信号中的至少一个字段确定为第一字段，包括以下至少一项：
在所述第一WiFi信号中存在N个连续的数据包的频率偏移值的标准差大于第一标准差阈值的情况下，将所述第二WiFi信号中短训练字段确定为所述第一字段，N为正整数；
在所述第一WiFi信号中存在N个连续的数据包的信道估计结果的标准差大于第二标准差阈值，且所述N个连续的数据包的数据字段的误差向量幅度的标准差大于第三标准差阈值，将所述第二WiFi信号中长训练字段确定为所述第一字段；
在所述第一WiFi信号中存在数据包的信号字段的误差向量幅度的大于第一阈值，将所述第二WiFi信号中信号字段确定为所述第一字段；
在所述第一WiFi信号中存在数据包的数据字段的误差向量幅度的大于第二阈值，将所述第二WiFi信号中数据字段确定为所述第一字段。
在本实施例中，所有WiFi信号中的数据包均可以分为STF(Short Training Field，短训练字段)、LTF(Long Training Field，长训练字段)、SIG(Signal Field，信号字段)以及数据(Data)字段。其中，短训练字段、长训练字段和信号字段为WiFi信号的帧头，数据字段则携带实际数据。
可以通过对第一WiFi信号中的数据包中各字段的字段属性进行分析，确定出第一WiFi信号中的数据包的数据状态，并基于数据状态来确定需要重新确定第二WiFi信号中哪些字段的目标发射功率。
具体地，可以通过分析第一WiFi信号中各数据包中短训练字段的字段属性，从而识别每一个数据包的频率偏移值，如果第一WiFi信号中存在N个连续的数据包的频率偏移值的标准差大于第一标准差阈值，可以认为这N个连续的数据包的频率偏移值的离散程度过高，从而使得第一WiFi信号的实际频率偏移和理想频率偏移的差异较大，因此需要将短训练字段确定为第一字段，重新确定第二WiFi信号中频率偏移对应的短训练字段的发射功率。
还可以通过分析第一WiFi信号中各数据包中长训练字段的字段属性，从而识别每一个数据包的信道估计结果，如果第一WiFi信号中存在N个连续的数据包的信道估计结果的标准差大于第二标准差阈值，那么可以进一步将这N个连续的数据包的数据字段的误差向量幅度的标准差和第三标准差阈值进行比较，如果误差向量幅度的标准差大于第三标准差阈值，可以认为这N个连续的数据包的信道估计结果的离散程度过高引起信道质量较差，因此需要将长训练字段确定为第一字段，重新确定第二WiFi信号中信道质量对应的长训练字段的发射功率。
此外，还可以通过分析第一WiFi信号中各数据包的信号字段和数据字段的字段属性，来确定信号字段的误差向量幅度和数据字段的误差向量幅度，误差向量幅度为衡量信号调制误差的指标。如果第一WiFi信号中存在数据包的信号字段的误差向量幅度的大于第一阈值，可以认为第一WiFi信号的信号字段和理想信号的信号字段差异过大，需要重新确定第二WiFi信号中信号字段的发射功率；同样的，如果第一WiFi信号中存在数据包的数据字段的误差向量幅度的大于第二阈值，可以认为第一WiFi信号的数据字段和理想信号的数据字段差异过大，需要重新确定第二WiFi信号中数据字段的发射功率。
通过上述方式，可以分别分析第一WiFi信号中每个字段的字段属性，来评估第一WiFi信号中数据包的数据状态，如果存在数据状态发生异常，则可以将异常的数据状态对应的字段确定为第一字段，并调整第二WiFi信号的第一字段的发射功率，以此来使第二WiFi信号中每个字段都接近信号传输的理想情况，保证终端设备和第二电子设备之间的通信质量较高。
在一些实施例中，所述根据所述数据状态确定所述第一字段的目标发射功率，包括：
获取所述第一字段的发射功率当前所处的第一档位等级；
将所述第一字段的发射功率调整为第二档位等级，直至所述第二档位等级下和所述第一字段对应的数据状态符合第二条件，所述第二档位等级为所述P个档位等级中和所述第一档位等级的上一个档位等级，其中，所述第一字段的发射功率包括P个档位等级；
将所述第二档位等级对应的发射功率确定为所述第一字段的目标发射功率。
在本实施例中，在信号强度小于信号强度阈值，且调制编码等级小于等级阈值的情况下，需要在终端设备当前的发射功率的基础上，增大终端设备发射的第二WiFi信号中第一字段的发射功率。
可以预先将发射功率的可调整区间设置为P个档位等级，每个档位等级对应一个发射功率，档位等级越高，则其对应的发射功率也就越高。在确定第一字段之后，可以进一步获取第一字段当前的发射功率对应的第一档位等级，并在第一档位等级的基础上，将第一字段的发射功率上调一档，如果在第二档位等级下第一字段对应的数据状态符合第二条件，则将第二档位等级对应的发射功率确定为第一字段的目标发射功率。否则继续按照上述方式调高第一字段的发射功率，直至第二档位等级下和所述第一字段对应的数据状态符合第二条件。
其中，第二条件为基于数据状态确定的第一电子设备发送的信号质量达到预先设置的状态阈值。
通过这种方式，能够使得第一字段的发射功率能够在可调的范围内进行灵活调整，使第一字段的最终发射功率准确的适配当前通信质量。
