具体实施方式
为了使本申请的目的、技术方案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，此处所描述的具体实施例仅用以解释本申请，并不用于限定本申请。不冲突的情况下，本申请中的实施例及实施例中的特征可以相互任意组合。
需要说明的是，虽然在装置示意图中进行了功能模块划分，在流程图中示出了逻辑顺 序，但是在某些情况下，可以以不同于装置中的模块划分，或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。
在本领域一些情形中，通过对信号进行编码调制以降低单位信息的传输功耗，从而降低通信系统的信息传输成本。
概率星座整形(Probabilistic Constellation Shaping，PCS，简称为概率整形)可通过调整与星座点的幅度相对应的比特的出现概率，以在保证QAM星座图中所有星座点的相对位置保持不变的情况下，使得出现概率由内向外依次降低，从而降低平均功率。
然而，当信号经过概率整形和前向纠错编码(Forward Error Correction，FEC)后，对信号进行交织的过程中，容易导致信号的排布方式发生串扰，使得无法对信号数据进行对应星座映射调制。
例如，在一些实施方案中，将概率整形与FEC编解码进行联合设计的难点在于：1)由于概率整形技术的加入，要求将送往调制模块的数据区分为未经过概率整形的数据以及经过概率整形映射的数据，其中未经过概率整形的数据对应调制后的符号位，经过概率整形映射的数据对应调制后的幅度位；2)为了打散信道引入的突发错误、提高译码性能，FEC编解码器通常需要和交织器一起配合工作，而交织器会将未经过概率整形以及经过概率整形映射的数据打散并使得数据相互混淆，根据相互混淆的数据导致无法得到想要的星座点分布，即无法带来整形增益。
基于此，本申请实施例提供数据发送方法、数据接收方法、数据发送终端、数据接收终端、系统、电子设备及计算机可读存储介质，能够使得信号交织的过程中，信号按预设方式排布，从而对信号进行有效的调制映射，实现整形增益。
第一方面，请参照图1，在一些实施例中，数据发送方法，包括：S100、获取概率整形信息和待发送的源数据；S200、根据概率整形信息对部分源数据进行概率整形处理，并得到整形数据及无整形数据；S300、将整形数据及无整形数据进行交织处理得到第一排序的第一交织数据；S400、对第一交织数据进行前向纠错编码处理，并得到校验信息；S500、对校验信息进行交织处理并得到交织校验信息；S600、对交织校验信息、整形数据及无整形数据进行调制处理并得到调制符号数据；S700、发送调制符号数据。
通过对待发送的源数据进行概率整形，以使源数据中代表低能量的比特出现概率高于代表高能量的比特，从而对星座点的出现概率进行调制。可以理解为，通过调节星座点出现的概率，从而降低信号的平均发射功率，以减少噪声对信号造成的损伤。
其中，数据发送方法可应用于通信系统中的数据发送终端，通过上述数据发送方法可降低信号的平均发射功率，以减少噪声对信号造成的损伤。数据发送终端可通过通信传输通道传输至数据接收终端。
通过对交织校验信息、整形数据及无整形数据进行调制处理以得到调制符号数据，从而避免将交织数据作为待映射数据。
在本领域一些情形中，一般将整形数据、无整形数据进行交织所形成的交织数据作为待映射数据，而交织处理容易造成整形数据、无整形数据的排序混乱，而无法得到目标调制符号数据。
例如，整形数据对应于调制符号数据的幅度位，无整形数据对应于调制符号数据的符号位。由于对整形数据、无整形数据进行交织处理，而导致原有数据的排序被打乱。因此， 在调制处理过程中，排序错乱的源数据将导致获得的调制符号数据的数据分布不符合预设参数，从而导致无法对信号进行整形增益。
在本申请实施例中，通过将对未交织的整形数据、无整形数据作为待映射数据，并将整形数据、无整形数据进行前向纠错编码处理的校验信息添加至待映射数据，以在调制符号数据的符号位中加入纠错码。通过在待映射数据中加入纠错码，以打散通信传输通道引入的突发错码，从而提高通信系统的译码能力；通过减少数据交织，以避免数据相互混淆，从而对信号进行有效的调制映射，从而实现整形增益。
在一些实施例中，概率整形信息包括以下的一个或多个：概率整形程度参数、概率整形类型参数、调制参数以及前向纠错编码参数。通过预设概率整形信息以限定对源数据的调节参数。例如，通过预设概率整形程度参数、概率整形类型参数以调节概率整形处理对源数据的整形程度及整形；通过预设前向纠错编码参数以确定对第一交织数据的进行前向纠错编码处理，以纠正第一交织数据中的误码；通过预设调制参数确定对源数据调制处理的调制方案。
根据源数据发送环境以预设置及调节概率整形信息，从而实现快速调用参数对源数据进行概率整形处理、前向纠错编码处理及调制处理。
例如，通过前向纠错编码处理以在源数据中加入冗余部分，从而使得数据处理中允许传输数据中存在有限个错码，且通常纠正有限个错码，以使得在不重传数据的情况下，保证数据可被通信系统正确识别。
在一些实施例中，根据概率整形信息对部分源信号数据进行概率整形处理，包括：根据调制参数以及前向纠错编码参数确定源信号数据的单位数据量及源信号单位数据量中的待整形数据量；根据概率整形信息和待整形数据量对源信号部分源数据进行概率整形处理。
例如，根据前向纠错编码参数得到对第一交织数据进行前向纠错编码处理后所得数据的码字长度；根据调制参数以确定调制处理的具体调制类型；根据码字长度、具体调制类型确定源信号数据的单位数据量及源信号单位数据量中的待整形数据量。
通过调制源信号数据的单位数据量及源信号单位数据量中的待整形数据量，以灵活调制通信系统中净信息速率，并增大通信系统的光信噪比容限，并提升信号的传输距离。
根据概率整形信息中的概率整形程度参数、概率整形类型参数及待整形数据量对源信号部分源数据进行概率整形处理。其中，进行概率整形处理的部分源数据可对应于输出数据中的检验符号位。
在一些实施例中，对交织校验信息、整形数据及无整形数据进行调制处理并得到调制符号数据，包括：根据预设符号映射规则对交织校验信息、整形数据及无整形数据进行调制处理得到调制符号数据；其中，预设符号映射规则包括：整形数据对应于调制符号数据的幅度位，无整形数据、交织校验信息对应于调制符号数据的符号位。
根据预设映射规则对交织校验信息、整形数据及无整形数据进行映射处理，并得按预设规则排布的调制符号数据。例如，将整形数据按照预设映射规则映射为调制符号数据的幅度位，将无整形数据、交织校验信息按照预设映射规则映射为调制符号数据的符号位。
在一些实施例中，调制处理为QAM调制(正交幅度调制)。通过对预设的映射规则对对交织校验信息、整形数据及无整形数据进行正交幅度调制处理以得到符合预设规则的调制符号数据。
其中，QAM调制作为一种矢量调制，将输入比特先映射(一般采用格雷码)到一个复平面(星座)上，形成复数调制符号；将符号的I、Q分量(对应复平面的实部和虚部，即水平和垂直方向)采用幅度调制，分别对应两个在时域上正交的载波(cosαt和sinαt)，从而提高频谱利用率。
例如，具有16个样点的16-QAM信号，每个样点可表示一种矢量状态，则16-QAM有16种矢量状态，而每4位二进制数规定了16种矢量状态中的一种矢量状态。可以理解为16-QAM中规定了16种载波和相位的组合。在实际应用场景中，QAM信号的样点数目越多，其传输效率越高，而根据不同的数据传输需求，可调节QAM信号中的样点数目。其中，QAM信号可包括16-QAM(16个样点)至1024-QAM(1024个样点)。
结合上述实施例，以对一具体实施例进行适应性说明。
通过预设概率整形信息以限定对源数据的调节参数。例如，通过预设概率整形程度参数、概率整形类型参数以调节概率整形处理对源数据的整形程度及整形；通过预设前向纠错编码参数以确定对第一交织数据的进行前向纠错编码处理，以纠正第一交织数据中的误码；通过预设调制参数确定对源数据调制处理的调制方案。
概率整形器根据概率整形程度参数、概率整形类型参数对源数据中的待概率整形部分进行概率整形处理，并得到整形数据及无整形数据。第一交织器将由概率整形器所得到的数据进行交织处理，以使得数据按照预设的第一排序进行排序的第一交织数据。
前向纠错编码器对第一交织数据进行前向纠错编码处理，并得到校验信息；第二交织器对校验信息进行交织处理并得到交织校验信息；符号调制器根据交织校验信息、整形数据及无整形数据进行调制处理并得到调制符号数据，并将调制符号数据经由通信传输通道传输至通信接收终端。
第一方面所提供的数据发送方法，通过对待发送的源数据进行概率整形，以使源数据中代表低能量的比特出现概率高于代表高能量的比特，从而对星座点的出现概率进行调制；通过减少整形数据、无整形数据的数据交织，以避免由于无整形数据、整形数据交织处理导致数据杂糅，从而保证对源数据进行有效的星座映射调制，进而实现整形增益。此外，通过控制符号调制器的数据输入速率，可灵活调节通信系统的净速率。
请参照图2A、图2B,图2A为标准16QAM星座图的星座点概率分布图；图2B为采用概率整形后的16QAM星座图的星座点概率分布图。其中，平面坐标表示位置，纵坐标表示星座点概率。
由图对比可知，通过调整与星座点的幅度相对应的比特的出现概率，以在保证QAM星座图中所有星座点的相对位置保持不变的情况下，使得出现概率由内向外依次降低，从而降低平均功率。
每4个数据比特映射为一个符号，其中，每2个数据比特映射表示一个星座点的实部或者虚部。即用于16QAM映射的待调制比特数据中有一半比特数据用于表示符号位，另一半比特数据表示幅度位。表示幅度位的比特数据来源于经过概率整形的源数据，表示符号位的比特数据来源于经过未经过概率整形的源数据及前向纠错编码处理所产生的校验数据。
请参照图3，QAM为星座映射，FEC为前向纠错处理。图中横坐标为速率适配性，纵坐标为性能。由图可知，通过概率整形的星座映射处理及固定的前向纠错处理，使得数据具有较高数量适配性的同时，可获得高性能。
此外，根据速率适配性、性能需要可对星座映射及前向纠错处理的类型进行适应性选择。
第二方面，请参照图4，在一些实施例中，数据接收方法，包括：S210、获取调制符号数据；S220、对调制符号数据进行解映射处理得到解映射数据，解映射数据包括交织校验信息、信息比特；S230、对交织校验信息进行解交织处理得到校验信息，对信息比特进行交织处理得到第一排序的第二交织数据；S240、对第二交织数据、校验信息进行前向纠错译码处理得到第三交织数据；S250、对第三交织数据进行解交织处理得到整形数据及无整形数据，并对整形数据进行解概率整形处理以得到源数据。
通过对接收到的调制符号数据进行解映射处理以解映射数据，解映射数据包括交织校验信息及信息比特。通过对交织校验信息进行解交织处理以通信发送终端前向纠错编码处理所得到的校验信息；通过对信息比特进行交织处理得到第一排序的第二交织数据，从而使获得与预设排序相匹配的第二交织数据。其中，第一排序的第二交织数据与通信发送终端中的第一交织数据的排序相匹配。通过对信息比特进行交织处理，以对信息比特中通信传输通道引入的误码进行离散化。
通过对第二交织数据、校验信息进行前向纠错译码处理得到第三交织数据，并对第三交织数据进行解交织处理得到整形数据及无整形数据，并对整形数据进行解概率整形处理以得到源数据。例如，第三交织数据中的幅度位对应于整形数据，第三交织数据中的符号位对应于无整形数据。
在一些实施例中，解映射处理包括有不同的判决映射方式。当解映射处理为硬判决解映射处理时，对调制符号数据进行解映射处理得到解映射数据具体为：对调制符号数据进行硬判决解映射处理，并得到解映射数据为单位数据比特的硬判值；当解映射处理为软判决解映射处理时，对调制符号数据进行解映射处理得到解映射数据具体为：对调制符号数据进行软判决解映射处理，则解映射数据为单位数据比特的对数似然比值。其中，通过选择不同的判决解映射处理方式，以适应于不同的通信环境，并根据对应的判决方式对调制符号数据进行判决解映射处理。
通过硬判值或者对数似然比值表示解映射数据，以使得数据接收方法适应于不同的数据传输系统的处理精度需求。
例如，通过硬判决解映射处理以对解映射处理所输出的解映射数据进行有限的N比特量化处理。通过预设设置门限值，当调制符号数据高于门限值时，输出结果被判定为1；当调制符号数据低于门限值时，输出结果被判定为0。即解映射数据为调制符号数据中单位数据比特的硬判值。
若解映射处理为软判决解映射处理，通过对调制符号数据进行软判决解映射处理，以得到解映射数据。其中，解映射数据为单位数据比特的对数似然比值。例如，通过符号解调器对调制符号数据进行量化，以得到调制符号数据所对应的每个单位数据比特的对数似然比值。通过对数似然比值以替代调制符号数据，并将对数似然比值作为译码源数据进行译码，以降低符号数据单元和\或符号数据组的译码错误概率。
结合上述实施例，以对一具体实施例进行适应性说明。
通过符号解调器接收调制符号数据并进行解映射处理，以得到解映射数据。通过交织器对解映射数据中的信息比特进行交织处理并得到第一排序的第二交织数据，通过解交织器对解映射数据中的交织校验信息进行解交织处理并得到校验信息。前向纠错译码器根据 第二交织数据、校验信息进行前向纠错译码处理，并得到第三交织数据。通过解交织器对第三交织数据进行解交织处理并得到整形数据及无整形数据；概率解整形器，被设置成对整形数据进行解整形处理，以得到对应的源数据。
其中，解交织器对前向纠错译码器所产生的数据进行解交织处理，以还原无整形数据、整形数据。而概率解整形器对整形数据进行解整形处理并得到部分源数据，将部分源数据及无整形数据传输至信宿，以整合得到完整的源数据。
故，第二方面所提供的数据发送方法，通过对调制符号数据中的整形数据、无整形数据、校验信息进行对应的交织处理或解交织处理，以使得数据按照预设规则排序。其中，解交织器对前向纠错译码器所产生的数据进行解交织处理，以还原无整形数据、整形数据。而概率解整形器对整形数据进行解整形处理并得到部分源数据，将部分源数据及无整形数据传输至信宿，以整合得到完整的源数据
第三方面，请参照图5、图7，在一些实施例中，数据发送终端100可为通信系统中的通信发送终端。数据发送终端100，包括：源数据模块110，被设置成产生源数据；概率整形器120，被设置成对源数据进行概率整形处理，并得到整形数据及无整形数据；第一交织器130，被设置成对整形数据及无整形数据进行交织处理得到第一排序的第一交织数据；前向纠错编码器140，被设置成对第一交织数据进行前向纠错编码处理并得到校验信息；第二交织器150，被设置成对校验信息进行交织处理；符号调制器160，被设置成对整形数据、无整形数据、校验信息进行调制处理并得到调制符号数据。
