在本实施例中提供了一种数据的处理方法,图2是根据本发明实施例的数据的处理方法的流程图,如图2所示,该流程包括如下步骤:
步骤S202,将待传输的数据分成G组,其中,每组分别对应包含D(g)个子组,每个所述子组中包括一个或多个数据,g为每组对应的标识,g=1,2,...,G,且D(g)>=1;
步骤S204,对每组内的D(g)个子组分别进行第一处理,得到D(g)组第一数据序列;
步骤S206,对每组内的D(g)组所述第一数据序列进行第二处理,得到每组的第二数据序列;
步骤S208,传输G组所述第二数据序列。
在上述S202中,将待传输的数据分成G组后,按照分组顺序可以得到第1组,第2组,… 第G组分组,其中,每组中都会包含一定数量的子组,每组所包含的子组数量可以按照每组的标号来表示,例如,第一组分组中包含的子组数量可以用D(1)来表示,第二组分组中包含的子组数量可以用D(2)来表示,以此类推,最后一组分组中包含的子组数量可以用D(G)来表示,其中,不同的分组中所包括的子组的数量可以相同也可以不同,或者部分分组的相同,部分分组的不同,各组中所包括的子组数量可以使默认配置的,也可以是按照一定规则配置的,还可以是基于实际应用场景或数据传输需求来配置的。
在上述S204中,在对每组内的D(g)个子组进行第一处理时,可以同时对该G个分组中所各自包括的子组进行该第一处理,也可以按照标号顺序来依次执行,或者分批次依次执行,当然,也可以基于实际情况,或者某些约束条件来确定执行顺序或执行方式,具体执行顺序不作限制。此外,在对每组分组中包括的D(g)个子组进行第一处理时,可以同时对该多个子组执行第一处理,也可以按照顺序依次对该对个子组执行第一处理,还可以分批次依次执行(即,每一批次中的子组同时执行第一处理,不同批次中的子组分次执行第一处理),当然,也可以基于实际情况,或者某些约束条件来确定执行顺序或执行方式,具体执行顺序不作限制。
在上述S206中,在对D(g)组第一数据序列执行上述第二处理时,其处理顺序也是不作限制的,具体处理顺序可以参考S204中的处理顺序,在此,不作赘述。

其中,执行上述S202一S208中的操作的可以是网络中的节点,例如,终端、基站或者其他具备通过网络传输数据能力的网元,本发明实施例对此不作限定。
通过上述实施例,对待传输的数据进行了分组,并且对分组后的数据分别进行了多次处理,然后在对处理后得到的数据序列进行传输。通过对数据的多次处理,可以方便后续使用复杂度较低的操作来对传输的数据进行滤波,从而有效降低数据传输时所产生的干扰,提高数据传输的准确度。

下面结合具体实施例对本发明实施例进行整体说明:
具体实施例一:
在本实施例中,以将待传输的数据分成2组为例进行说明,当然,在实际应用中,还可以分成更多组,例如,分成4组、8组、10组等等。
如图3所示,待传输数据分成2组,第一组使用单载波波形进行调制,第二组使用多载波波形进行调制。
第一组再分成G(1)个子组,每个子组使用单载波波形进行调制。每个子组的数据可以选择插入参考序列或者插零,或者选择傅里叶变换和逆变换。本实施例中,每个子组的数据选择插入参考序列。第一组经过第一处理之后,形成G(1)组长度相等的第一数据序列。G(1)组第一数据序列经过第二处理后形成一组数据序列。本实施例中,第二处理为傅里叶逆变换。所述傅里叶逆变换为:每G(1)个数据进行一个所述傅里叶逆变换,所述G(1)个数据分别来自于G(1)组数据序列。对每G(1)个数据进行一个所述傅里叶逆变换,还包括增加多个零数据,然后进行傅里叶逆变换,所述傅里叶逆变换的IFFT点数大于G(1)。每G(1)个数据进行一个所述傅里叶逆变换形成一组时域数据序列,多个所述傅里叶逆变换生成的时域数据序列串行连接形成数据序列S1。
第二组再分成G(2)个子组,每个子组使用多载波波形进行调制。每个子组的数据可以选择傅里叶逆变换。第二组经过第一处理之后,形成G(2)组长度相等的第一数据序列。G(2)组第一数据序列经过第二处理后形成一组数据序列。本实施例中,第二处理为傅里叶逆变换,多个所述傅里叶逆变换生成的时域数据序列串行连接形成数据序列S2。
所述第二处理还包括:在傅里叶逆变换之后,进行滤波操作。所述滤波为多相滤波操作,并且所使用的波形函数不同或相同(波形函数不同的情况包括,比如不同的波形函数类型,或者同一种波形函数类型,但具体参数不同)。
然后对数据序列S1和数据序列S2进行第三处理以形成一组数据序列中,所述处理包括:点乘操作、加操作。点乘操作可以对数据序列S1进行点乘操作,也可以对数据序列S2进行点乘操作。本实施例中,数据序列S2与序列ejθi(其中,i=0,1,2,...)进行点乘后,然后与 数据序列S1进行加操作,形成一组时域数据序列。
如果在第二处理中没有包括滤波或加窗操作,并且所需要的波形函数相同的话,则在第三处理中,还包括对所述一组时域数据序列进行滤波或加窗操作。
在本实施例中,可以通过发射节点传输通过上述方式形成的一组时域数据序列,其中,在通过发射节点传输所述一组时域数据序列时,可以在一定频域带宽和一定时域长度的物理资源上传输所述一组时域数据序列。
具体实施例二:
在本实施例中,还是以将待传输的数据分成2组为例进行说明,当然,在实际应用中,还可以分成更多组,例如,分成4组、8组、10组等等。
如图4所示,待传输数据分成2组,第一组使用不同波形类型的混合调制,第二组使用多载波波形进行调制。
第一组再分成G(1)个子组,每个子组使用单载波或多载波波形进行调制。每个子组的数据可以选择插入参考序列或者插零,或者选择傅里叶逆变换,或者不做处理。第一组经过第一处理之后,形成G(1)组长度相等的第一数据序列。G(1)组第一数据序列经过第二处理后形成一组数据序列。本实施例中,第二处理为傅里叶逆变换。所述傅里叶逆变换为:每G(1)个数据进行一个所述傅里叶逆变换,所述G(1)个数据分别来自于G(1)组数据序列。对每G(1)个数据进行一个所述傅里叶逆变换,还包括增加多个零数据,然后进行傅里叶逆变换,所述傅里叶逆变换的IFFT点数大于G(1)。每G(1)个数据进行一个所述傅里叶逆变换形成一组时域数据序列,多个所述傅里叶逆变换生成的时域数据序列串行连接形成数据序列S1。
第二组再分成G(2)个子组,每个子组使用多载波波形进行调制。每个子组的数据可以选择傅里叶逆变换。第二组经过第一处理之后,形成G(2)组长度相等的第一数据序列。G(2)组第一数据序列经过第二处理后形成一组数据序列。本实施例中,第二处理为傅里叶逆变换,多个所述傅里叶逆变换生成的时域数据序列串行连接形成数据序列S2。
所述第二处理还包括:在傅里叶逆变换之后,进行滤波操作。所述滤波为多相滤波操作,并且所使用的波形函数不同(比如不同的波形函数类型,或者同一种波形函数类型,但具体参数不同)。
然后对数据序列S1和数据序列S2进行第三处理以形成一组数据序列中,所述处理包括:点乘操作、加操作。点乘操作可以对数据序列S1进行点乘操作,也可以对数据序列S2进行点乘操作。本实施例中,数据序列S2与序列ejθi(其中,i=0,1,2,...)进行点乘后,然后与数据序列S1进行加操作,形成一组时域数据序列。
在本实施例中,可以通过发射节点传输通过上述方式形成的一组时域数据序列,其中,在通过发射节点传输所述一组时域数据序列时,可以在一定频域带宽和一定时域长度的物理资源上传输所述一组时域数据序列。
具体实施例三:
如图5所示,传输所述一组时域数据序列,还包括,对所述一组时域数据序列进行数模转换DAC、射频链路RF传输过程。
通过以上的实施方式的描述,本领域的技术人员可以清楚地了解到根据上述实施例的方法可借助软件加必需的通用硬件平台的方式来实现,当然也可以通过硬件,但很多情况下前者是更佳的实施方式。基于这样的理解,本发明实施例的技术方案本质上或者说对现有技术做出贡献的部分可以以软件产品的形式体现出来,该计算机软件产品存储在一个存储介质(如ROM/RAM、磁碟、光盘)中,包括若干指令用以使得一台终端设备(可以是手机,计算机,服务器,或者网络设备等)执行本发明实施例各个实施例所述的方法。
在本实施例中还提供了一种数据的处理装置,该装置用于实现上述实施例及优选实施方式,已经进行过说明的不再赘述。如以下所使用的,术语“模块”可以实现预定功能的软件和/或硬件的组合。尽管以下实施例所描述的装置较佳地以软件来实现,但是硬件,或者软件和硬件的组合的实现也是可能并被构想的。
