具体实施方式
如前所述,现有RFID中协议支持的覆盖距离受限,例如在10m以内,由于距离过近,极大的限制了RFID协议在实际场景中的应用。
具体而言,1995年国际标准化组织(ISO/IEC)联合技术委员会JTCl设立了子委员会SC31(以下简称:“SC31”),负责RFID标准化研究工作。SC31委员会由来自各个国家的代表组成,如英国的BSIIST34委员、欧洲CENTC225成员。他们既是各大公司内部咨询者,也是不同公司利益的代表者。因此在ISO标准化制定过程中,有企业、区域标准化组织和国家三个层次的利益代表者。
SC31子委员会负责RFID标准可以分为四个方面:数据标准(如编码标准ISO/IEC15691、数据协议ISO/IEC15692、ISO/IEC15693,解决了应用程序、标签和空中接口多样性的要求,提供了一套通用的通信机制)、空中接口标准(ISO/IEC18000系列)、测试标准(性能测试ISO/IEC18047和一致性测试标准ISO/IEC18046)、实时定位(RTLS)(ISO/IEC24730系列应用接口与空中接口通信标准)方面的标准。
这些标准涉及到RFID标签、空中接口、测试标准、读写器与到应用程序之间的数据协议,它们考虑的是所有应用领域的共性要求。ISO对于RFID的应用标准是由应用相关的子委员会制定。RFID在物流供应链领域中的应用方面标准由ISOTC122/104联合工作组负责制定,包括ISO17358应用要求、ISO17363货运集装箱、ISO17364装载单元、ISO17365运输单元、ISO17366产品包装、ISO17367产品标签。RFID在动物追踪方面的标准由ISOTC23SC19来制定,包括ISO11784/11785动物RFID畜牧业的应用,ISO14223动物RFID畜牧业的应用高级标签的空中接口、协议定义。
由ISO制订的RFID标准内容可知,RFID应用标准是在RFID编码、空中接口协议、读写器协议等基础标准之上,针对不同使用对象,确定了使用条件、标签尺寸、标签粘贴位置、数据内容格式、使用频段等方面特定应用要求的具体规范,同时也包括数据的完整性、人工识别等其他一些要求。通用标准提供了一个基本框架,应用标准是对它的补充和具体规定。这一标准制订思想,既保证了RFID技术 具有互通与互操作性,又兼顾了应用领域的特点,能够很好地满足应用领域的具体要求。
由上可知,RFID的可应用场景极为广泛,例如可以面向零售、工业、电力、医药、畜牧、物流等垂直行业,提供覆盖广、成本低、定位准的无源物联。
经过研究发现,增大距离可能会导致信道衰落和干扰问题愈发严重,影响通信质量。
有鉴于此,本申请实施例提供一种通信方法,通过采用第一编码方式对待编码数据进行编码以得到第一数据,采用第二编码方式对所述第一数据进行编码以得到第二数据,可以实现多轮连环编码处理,有效提升更广的覆盖距离下的通信性能,以及对抗更广的覆盖距离下的信道衰落和干扰,并且由于所述第一编码方式与所述第二编码方式不同,可以结合多种编码方式的优点,进一步提高编码后数据的抗干扰能力。

为使本发明的上述目的、特征和有益效果能够更为明显易懂,下面结合附图对本发明的具体实施例做详细的说明。
参照图1,图1是本申请实施例中第一种通信方法的流程示意图。
图1示出的方法可以由发送端执行。图1示出的方法可以包括S11至S13。其中,本申请中各个步骤编号中的S表示步骤(step)。
S11,采用第一编码方式对待编码数据进行编码以得到第一数据。
进一步地,所述第一编码方式可以选自:分组编码、可靠性编码、空域分集编码、扩频码编码。
其中,分组编码可以用(n,k)表示,用于指示采用2k个长度都为n的码字构成的集合,对k比特信息进行编码,每个码字都是一个n维矢量。k用于表示待编码的信息比特长度,n用于表示码字长度。
其中,k的选值可以选自0至K,其中,K用于表示待编码数据的原始信息比特长度。
示例性的,可以采用适当的k、n,以降低编码复杂度。
例如,k可以小于预设门限N1,n可以小于预设门限N2。其中,N1例如可以取值为10,或其他适当数值,N2例如可以取值为10,或其他适当数值。
其中,q进制分组码其码字矢量的元素取值于有限域FG(q):{0,1,...,q-1},即每个码字中的元素都是从{0,1,...,q-1}中选取的。
非限制性的,以二级制为例(即q=2),则每个码字中的元素都是从{0,1}中选取的;以八级制为例(即q=8),则每个码字中的元素都是从{0,1,2,3,4,5,6,7}中选取的。
以q=2,k=4,2k=16,n=5为例,一种分组编码的示例如下(包含16个5-bit码字):
C(24)={“11111”,“11110”,“11101”,“11011”,“10111”,“01111”,“00111”,“10011”,“11001”,“11100”,“01011”,“01101”,“01110”,“10101”,“10110”,“11010”}。
其中,可靠性编码是以提升可靠性为主,例如以重复的序列来替换bit 0或者1,或者,通过分集发送的方式提升可靠性。
进一步地,所述可靠性编码可以为ucode编码或重复编码。
其中,ucode编码可以是采用预设数量的预设序列分别表示比特(bit)1和比特0。
非限制性地,可以采用1010……10表示比特1,还可以采用0000……00表示比特0,其中,1010……10和0000……00的字符数量可以为预设数量P。
ucode编码可以是采用预设数量的预设重复序列分别表示比特(bit)1和比特0。
非限制性地,可以采用1111……11表示比特1,还可以采用0000……00表示比特0,其中,1111……11和0000……00的字符数量可以为预设数量Q。
其中,正交空时分组码(orthogonal space-time block coding,OSTBC)编码是采用多个(如2个、4个等)发送天线和一个接收天线的编码方法。具体而言,当天线的数目一定时,空时格码(Space Time Trellis Code,STTC)的译码复杂度与天线的个数和数据速率成指数增长。为了解决译码复杂度的问题,使用两个发送天线的传输方法,采用两个发送天线和一个接收天线,这种算法的性能与采用最大比合并算法(如一个发送天线,两个接收天线)的性能是相同的。具体算法可以采用下述表示:
其中,Sa用于表示尺寸为L×K(天线×符号槽)的OSTBC码字。每个OSTBC码字都来自一组属于某个符号相位的矢量信息符号ca∈CRK。在上述R=1的双天线(L=2)系统的OSTBC编码示例(又可称为Alamouti代码)中,每行可以表示不同的天线,每列可以表示不同的时间。具体而言,其中,第一个时刻发送第一行,第二个时刻发送第二行,依此类推。因此,矩阵的每一列符号实际是由同一副发送天线在不同时刻发送的。
考虑到编码矩阵之间的相互正交性,在同一副天线上发送出去的符号与另外任意天线上发送出去的符号是正交的,故这类码称为正交空时分组码。
空时编码(space-time coding,STC)技术是利用阵列天线处理技术开发多输入多输出系统(Multiple-Input Multiple-Output,MIMO)性能,可以有效抵消衰落,提高频谱效率。
具体算法可以采用下述表示:
非限制性的,可以是通过从Alamouti代码中删除减号和共轭号得到的。
S12,采用第二编码方式对所述第一数据进行编码以得到第二数据。
进一步地,所述第二编码方式可以选自:分组编码、可靠性编码、空域分集编码、扩频码编码。
其中,所述第一编码方式与所述第二编码方式不同。
在本发明实施例中,所述第一编码方式选自:分组编码、可靠性 编码、空域分集编码、扩频码编码;和/或,所述第二编码方式选自:分组编码、可靠性编码、空域分集编码、扩频码编码。采用上述方案,可以在更丰富的编码方式中选择不同的编码方式作为第一编码方式和第二编码方式,从而进一步结合多种编码方式的优点,有效提高编码后数据的抗干扰能力。
S13,发送编码后数据。
需要指出的是,编码后数据是最后一次编码得到的编码后数据,在图1示出的通信方法中,编码后数据可以是第二数据。
在本发明实施例中,通过采用第一编码方式对待编码数据进行编码以得到第一数据,采用第二编码方式对所述第一数据进行编码以得到第二数据,可以实现多轮连环编码处理,有效提升更广的覆盖距离下的通信性能,以及对抗更广的覆盖距离下的信道衰落和干扰,并且由于所述第一编码方式与所述第二编码方式不同,可以结合多种编码方式的优点,进一步提高编码后数据的抗干扰能力。
需要指出的是,本发明实施例中的技术方案的应用背景可以是:室外(Outdoor)站间距200~500m,还可以是室内(indoor)站间距30~50m。
进一步地,所述方法还可以包括:确定编码参数表,所述编码参数表包含以下一项或多项:用于所述第一编码方式的第一编码参数、用于所述第二编码方式的第二编码参数。
在本发明实施例中,通过确定编码参数表,所述编码参数表包含以下一项或多项:用于所述第一编码方式的第一编码参数、用于所述第二编码方式的第二编码参数。采用上述方案,发送端和接收端可以通过包含多项信息的编码参数表确定多种参数的参数值,相比于每次通信均需要收发编码参数,可以有效节省信令开销和提高通信质量。
更进一步地,所述方法还可以包括:发送所述编码参数表中的索引号;其中,每个索引号用于指示所述编码参数表中的一行。
在本发明实施例中,发送所述编码参数表中的索引号;其中,每个索引号用于指示所述编码参数表中的一行。采用上述方案,发送端可以通过发送索引号即可使接收端确定多个编码参数,进一步节省信令开销。
更进一步地,所述编码参数表中的索引号的发送方式可以选自:下行控制信息(Downlink Control Information,DCI)、媒体访问控制层控制元素(Media Access Control-Control Element,MAC CE)或无线资源控制(Radio Resource Control,RRC)。
在本发明实施例中,可以根据具体情况,选择适当的方式发送编码参数表中的索引号。
更进一步地,所述编码参数表可以为预定义的。
在本发明实施例中,所述编码参数表为预定义的,例如可以通过通信协议预先设置,从而可以无需在发送端和接收端之间进行交互,进一步节省信令开销。
实施例一
所述第一编码方式为分组编码,所述第二编码方式为可靠性编码。
参照图2,图2是本发明实施例中第二种通信方法的信令交互示意图。图2示出的方法可以用于发送端,还可以包括S21至S23:
S21,发送端采用分组编码对待编码数据进行编码以得到第一数据。
S22,发送端采用可靠性编码对所述第一数据进行编码以得到第二数据。
S23,发送端向接收端发送第二数据。
在具体实施中,有关分组编码和可靠性编码的更多详细内容请参照图1中的S11和S12的描述进行执行,此处不再赘述。
参照表1,表1是本发明实施例中第一种编码参数表。
表1
如表1所示,所述待编码的信息比特长度k、码字长度n以及码率可以用于实施分组编码,重复序列的码片长度N可以用于实施可靠性编码,码率可以是所述第一编码方式以及所述第二编码方式中的一个的码率。
进一步地,所述待编码的信息比特长度k可以小于等于预设阈值。
在本发明实施例中,所述待编码的信息比特长度k小于等于预设阈值,从而可以控制待编码的信息比特长度k,降低分组编码的最小单元的长度,降低分组编码的编码复杂度。
进一步地,所述码率越大,所述重复序列的码片长度N越大。
在本发明实施例中,所述码率越大,所述重复序列的码片长度N越大,从而可以在采用码率较大的分组编码进行编码后,采用较长的重复序列的码片长度N进行可靠性编码,进一步提高编码后数据的抗干扰能力。
进一步地,所述可靠性编码中的ucode编码满足:所述重复序列的码片长度N基于网络侧配置ID或者预设ID或者小区ID确定。
在本发明实施例中,所述可靠性编码中的ucode编码满足:所述重复序列的码片长度N基于网络侧配置ID或者预设ID或者小区ID确定,从而可以使用ucode达到扩频的效果。
在本发明实施例中,所述第一编码方式为分组编码,所述第二编码方式为可靠性编码;所述第一编码参数、第二编码参数满足以下一项或多项:所述第一编码参数包含以下一项或多项:所述待编码的信息比特长度k、码字长度n以及码率;所述第二编码参数包含可靠性编码中采用的重复序列的码片长度N。采用上述方案,可以通过在编码参数表中设置所述待编码的信息比特长度k、码字长度n以及码率中的一项或多项,实现在节省信令开销的同时,提高分组编码的准确性和可靠性,还可以通过在编码参数表中设置重复序列的码片长度N,实现在节省信令开销的同时,提高可靠性编码的准确性和可靠性,从而可以结合分组编码和可靠性编码的优点,采用多轮连环编码处理待编码数据,进一步提升更广的覆盖距离下的通信性能。进一步地,通过将可靠性编码设置在分组编码之后,由于分组编码是基于原始信息的码字进行编码,可靠性编码是以提升可靠性为主的编码,通常是采用重复性的bit或者序列或者码片的方式得出编码后的bit或者序列或者码片,因此可以进一步降低编解码的复杂度,提高编解码的准确性。
