  • PAPR refers to the ratio of the peak power to the average power of the signal. Since the dynamic range of the power amplifier is limited, when the PAPR is too high, the power amplifier will enter the nonlinear region, causing nonlinear distortion of the signal after passing through the power amplifier, resulting in frequency domain expansion and in-band signal distortion, and reducing system performance. In order to avoid entering the nonlinear region, power backoff is required. The higher the PAPR, the lower the power that needs to be backed off. However, power backoff will lead to a decrease in coverage performance, so reducing PAPR is beneficial to improving coverage.

Description

基于序列的信号处理方法、装置及存储介质
本申请要求于2022年09月30日提交中国国家知识产权局、申请号为202211214774.5、发明名称为“基于序列的信号处理方法、装置及存储介质”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本申请涉及通信技术领域，尤其涉及一种基于序列的信号处理方法、装置及存储介质。
背景技术
为了提高信号的覆盖范围，使用频域扩展(spectral extension)和频域频谱整形(frequency-domain spectral shaping，FDSS)的方式可以降低离散傅里叶变换扩频的正交频分复用(discrete fourier transform spread orthogonal frequency division multiplexing，DFT-S-OFDM)的峰值平均功率比(peak-to-average power ratio，PAPR)。
解调参考信号(demodulation reference signal，DMRS)的PAPR/立方度量(cubic metric，CM)需要小于或者等于数据信号的PAPR/CM。对于数据信号采用四相相移键控(quadrature phase shift keying，QPSK)调制的场景，当DMRS长度大于或等于36个子载波时，采用Zadoff-Chu序列(简称“ZC序列”)作为DMRS序列，当DMRS序列长度为6/12/18/24时，采用计算机搜索序列(computer generated sequence，CGS)。DMRS序列需要与数据信号经过相同的滤波器来保证信道估计性能，然而由ZC序列或者CGS序列生成的DMRS序列经过FDSS处理后的PAPR/CM性能要劣于经过FDSS和频域扩展处理的数据信号的PAPR/CM性能。
有鉴于此，在不同的DMRS长度下如何配置DMRS序列，降低DMRS序列的PAPR/CM，是亟待解决的问题。

需要说明的是，本申请实施例中的术语“系统”和“网络”可被互换使用。
PAPR是指信号的峰值功率与平均功率的比值。由于功率放大器的动态范围是有限的，当PAPR过高会导致功放进入非线性区，导致信号经过功放后产生非线性失真，造成频域扩展和带内信号畸变，降低系统性能。为了避免进入非线性区，需要功率回退，PAPR越高，需要回退的功率也就越低高，然而功率回退会导致覆盖性能下降，因此降低PAPR有利于提高覆盖。
除了PAPR，CM也是一个常用的代表性指标，可以很好地表征波形所需的功率回退值。CM越小，当前所需的功率回退值也越小。
新无线接入技术(new access-technology，NR)中为了提高上行的覆盖，支持了DFT-S-OFDM波形。相对于OFDM波形，DFT-S-OFDM波形可以有效降低信号的PAPR，从而提高覆盖。
如图4所示，为生成DFT-S-OFDM信号的流程示意图。该流程包括以下步骤：
以采用低密度奇偶校验(low density parity check，LDPC)编码，QPSK调制，子载波个数为M为例，DFT-S-OFDM信号的生成流程为：
(1)K个数据比特{a(0)，a(1)，…，a(K-1)}，经过LDPC编码，得到2M个编码码字{b(0)，b(1)，…，b(2M-1)}，其中码率R＝K/2M；
(2)2M个编码码字{b(0)，b(1)，…，b(2M-1)}，经过QPSK调制后，得到M个调制符号{s(0)，s(1)，…，s(M-1)}；
(3)M个调制符号经过M点的离散傅里叶变换(discrete Fourier transform，DFT)后得到频域信号{X(0)，X(1)，…，X(M-1)}；
(4)将频域信号映射到M个子载波上，并进行N点的快速傅立叶反变换(inverse fast Fourier transformation，IFFT)得到时域信号{x(0)，x(1)，…，x(N-1)}。N一般由系统带宽决定，且大于M。在存在发射多天线时，频域信号还可以乘以预编码矩阵后再进行子载波映射；
(5)对时域信号加循环前缀(cyclic prefix，CP)后进行数模转换得到模拟信号，并通过天线发送。
其中，QPSK调制使用4种不同相位来表示不同的信息，因此一个QPSK调制符号可以承载2个码字信息，其调制阶数为2。QPSK的4个相位通常可以为{0，π/2，π，3π/2}或{π/4，3π/4，5π/4，7π/4}。以相位为{π/4，3π/4，5π/4，7π/4}为例，QPSK的调制符号可以表示为ak和bk为两个编码码字。
在通信系统中通常使用参考信号获取信道信息。在NR中，通常利用DMRS来获取基站和终端间信道的信息，DMRS通常用于确定接收端的接收矩阵和辅助数据解调，DMRS信道估计的质量直接影响数据的解调性能。在NR的物理上行共享信道(physical uplink shared channel，PUSCH)中，当使用DFT-S-OFDM波形时，DMRS序列和数据符号以时分复用的方式传输，即部分符号仅传输DMRS序列。对于上行单载波波形，DMRS在频域上使用的梳齿(comb)结构，如图5所示，灰色块表示DMRS占据的资源单元(resource element，RE)，空白的块可以是其它终端的DMRS占据的RE或者不使用的RE。
DMRS序列的发送流程为：
(1)生成DMRS序列，将DMRS序列映射到P个子载波上，并进行N点的IFFT得到时域DMRS信号{y(0)，y(1)，…，y(N-1)}。N一般由系统带宽决定，且大于P。在存在发射多天线时，频域信号还可以乘以预编码矩阵后再进行子载波映射。
(2)对时域DMRS信号加CP后进行数模转换得到模拟信号，并通过天线发送。
为了进一步提高覆盖，可以使用频域扩展和FDSS的方式来降低DFT-S-OFDM的PAPR。
频域扩展是指对频域信号进行循环扩展。例如，原始的DFT-S-OFDM中，信号占M个子载波，频域信号为{X(0)，X(1)，…，X(M-1)}。将频域信号进行循环扩充，例如扩展E个元素，其中向左(或者称向前)扩展P个元素，向右(或者称向后)扩展E-P个元素，得到包含Q＝M+E个元素频域信号{X(M-P),X(M-P+1),…,X(M-1),X(0),X(1),…,X(M-1),X(0),X(1),…,X(E-P-1)}。其中，频域扩展比例定义为：
如图6所示，为示例的一种频域扩展的示意图，以M＝8，E＝4，P＝2为例，扩充前的频域信号为{X(0),X(1),X(2),X(3),X(4),X(5),X(6),X(7)}，扩充后的频域信号为{X(6),X(7)，X(0),X(1),X(2),X(3),X(4),X(5),X(6),X(7)，X(0),X(1)}。扩充后的频域信号映射到M+E个子载波上并发送。
FDSS是指对频域信号进行加窗滤波(如根升余弦(root raised cosine，RRC)滤波、三抽头滤波(three tap filter))。例如，原始的DFT-S-OFDM中，信号占M个子载波，频域信号为{X(0),X(1),…,X(M-1)}，滤波器系数为{W(0),W(1),…,W(M-1)}。如图7所示，为频谱整形操作的示意图，加窗滤波就是指将频域信号与滤波器系数逐位相乘，滤波后的频域信号为{X(0)W(0),X(1)W(1),…,X(M-1)W(M-1)}。
频域扩展和频谱整形可以单独使用也可以同时使用。同时使用时，通常是先将频域信号进行循环扩充，然后再逐位乘以滤波器系数。例如，原始的DFT-S-OFDM中，信号占M个子载波，频域信号为{X(0),X(1),…,X(M-1)}。先循环扩充得到频域信号{X(M-P),X(M-P+1),…,X(M-1),X(0),X(1),…,X(M-1),X(0),X(1),…,X(E-P-1)}，然后和滤波器系数 {W(0),W(1),…,W(M+E)}逐位相乘得到最终的频域信号，再映射到子载波上并发送。
如图8所示，为FDSS和频域扩展对PAPR的影响示意图，展示了DFT-S-OFDM波形QPSK调制时不同方案PAPR的互补累积分布函数(complementary cumulative distribution function，CCDF)，通常以10-4点判断PAPR的大小。曲线1表示DFT-S-OFDM波形QPSK调制、且未使用FDSS；曲线2表示DFT-S-OFDM波形QPSK调制且未经过频域扩展；以及曲线3表示DFT-S-OFDM波形QPSK调制使用FDSS且经过比例为25％的频域扩展。从图8中可以看到使用FDSS和频域扩展对PAPR的影响，可以看出FDSS和频域扩展可以有效地降低数据信号的PAPR。
当数据比特采用QPSK调制或者更高阶的调制方式时，当DMRS长度大于或等于36时采用Zadoff-Chu(ZC)序列，ZC序列的生成方式为：
fn＝xq(n modNZC)  ……公式1
其中，n的取值范围为0到N-1，Nzc是小于N的最大质数，q是ZC序列的根，由高层的配置信息和符号的位置和序列长度Nzc确定，具体地，其中v＝0或1，u∈{0,1,…,29}。fn为最终生成的DMRS序列。
当DMRS长度等于30时，采用以下公式生成：
其中Mzc表示序列的长度，长度为30的DMRS序列本质上是截断的ZC序列(长度为31的ZC序列舍弃末尾的一个元素得到),fn为最终生成的DMRS序列。
当DMRS长度为6、12、18或者24时，生成公式为：
其中，为序列中的元素，序列属于下列所示的序列集合，其中每行表示序列的一种可能取值。

其中，fn为最终生成的DMRS序列。
DMRS的PAPR/CM需要小于或者等于数据信号的PAPR/CM。对于上述根据公式4生成的QPSK序列，该序列使用FDSS、FDSS和频域扩展后的CM性能如图9所示。仅使用FDSS后QPSK序列的CM性能(如曲线2所示的数据)以及同时使用FDSS和频域扩展后的QPSK序列的CM性能(如曲线1所示的数据)均要劣于经过FDSS和频域扩展处理后的数据信号(如曲线3所示的数据)。
针对上述问题，本申请提供一种基于序列的信号处理方案，在数据采用QPSK或者更高阶的调制方式，且DMRS序列长度小于第一阈值时，使用由QPSK或者8PSK调制的时域序列依次经过DFT变换和频域扩展处理得到的DMRS序列，将该DMRS序列映射到Q个子载波上，生成第一信号并发送。从而可以使得DMRS序列的PAPR/CM小于等于数据信号的PAPR/CM。
如图10所示，为本申请实施例提供的一种基于序列的信号处理方法的流程示意图，示例性地，该方法可以包括以下步骤：
S1001.发送端确定包括Q个元素的序列[Sk]。
该方法可以应用于上行传输，本实施例中的发送端可以是终端，本实施例中的接收端可以是网络设备；该方法也可以应用于下行传输，本实施例中的发送端可以是网络设备，本实施例中的接收端可以是终端。
本实施例中，数据符号由调制符号经过离散傅里叶变换后得到。调制符号的调制方式为QPSK或者更高调制阶数的调制方式。
进一步地，在步骤S1001之前，还可以包括：确定数据子载波数量、频域扩展比例和FDSS。针对下行传输，则由网络设备自身确定数据子载波数量、频域扩展比例和FDSS。针对上行传输，则网络设备可以通过下行控制信息(downlink control information，DCI)指示数据子载波数量；频域扩展比例可以是预配置给终端的，或者网络设备可以指示频域扩展比例的相关信息，终端可以根据频域扩展比例的相关信息通过查表或查公式获得频域扩展比例；FDSS是由终端设备自行确定的。
其中，Sk为序列[Sk]中的元素，序列[Sk]为满足预设条件的序列。一个预设条件为：M小于第一阈值时，Sk＝A·f(k+M-P)modM·e2π·j·α·k，A为非零复数，α为实数，(k+M-P)modM表示(k+M-P)除以M的余数，Q是M和E之和，P为大于或等于0且小于或等于E的整数，k属于{0，…，Q-1}。示例性地，上述的第一阈值为30。
另一种可能的实现方式中，上述的第一阈值为α*12，α是正整数，可以取值为4，16，32等。
fn是序列[fn]中的元素，序列[fn]为包括M个元素的序列，元素fn满足n的取值为0到M-1，rn为包括M个元素的序列[rn]中的元素。其中，fn为对时域序列rn进行DFT变换得到的序列。(k+M-P)modM的本质为对序列[fn]进行频域扩展操作，以M＝4,E＝2,P＝1为例，那么序列[f(0),f(1),f(2),f(3)]进行频域扩展得到[f(3),f(0),f(1),f(2),f(3),f(0)]。
在一个可能的实现中，Q＝M即频域扩展比例为0％。
以调制方式为QPSK为例，一种方案为：当所述M小于30时，序列[fn]为采用由调制或者8PSK调制的时域序列依次经过DFT变换和频域扩展得到的序列。
具体地，rn的取值集合可以有以下几种实现：
在一个实现中，M＝6时，rn的取值集合为即可以使用公式5和公式6得到序列[fn]，并将序列[fn]进行频域扩展处理得到DMRS序列[Sk]。

在另一个实现中，rn的取值集合为即
在数据采用QPSK调制或更高阶的调制时，当所述M小于30时，现有方案采用如公式4所示的QPSK序列，而本实施例采用由或者8PSK调制的时域序列依次经过DFT变换和频域扩展处理得到的DMRS序列。本实施例的上述实现本质上生成了调制或者8PSK调制的DFT-s-OFDM波形，因此其PAPR/CM较低，使用FDSS和/或频域扩展后还可以进一步降低PAPR/CM，因此DMRS长度小于30时采用上述实现中给出的序列可以获得较优PAPR/CM性能。
需要注意的是，在实现中发送端可以直接确定序列[Sk]，然后将序列[Sk]映射到Q个子载波上，生成第一信号，也可以先确定序列[fn]，然后通过循环扩展处理得到序列[Sk]，也可以通过其他方式确定序列[Sk]，本实施例对此不做限定。
如图11所示，为本申请实施例提供的一种由或者8PSK调制的时域序列依次经过DFT变换和频域扩展处理得到的DMRS序列使用FDSS后的CM性能示意图。所述M为18时，分别采用RRC滤波器和三抽头滤波器，DMRS序列的CM性能如图11所示，无论使用RRC滤波器还是三抽头滤波器，DMRS序列的CM性能均远优于数据信号。其中，曲线1为经过RRC滤波器且扩展比例为25％的DMRS序列；曲线2为经过三抽头滤波器且扩展比例为50％的DMRS序列；曲线3为经过RRC滤波器和比例为25％的频域扩展的数据信号；以及曲线4为经过三抽头滤波器和比例为50％的频域扩展的数据信号。
除了PAPR/CM性能，DMRS的频域平坦度和互相关性能也很重要。其中，频域平坦度决定了信道估计的性能，从而影响了系统的吞吐性能。互相关性能决定的不同小区的终端的抗干扰性能。本申请中，频域平坦度的值为频域序列中各元素的功率最小值与功率平均值的比值的对数。互相关值的计算如下：假设两条N长的序列a＝(a0,a1,…,aN-1)和b＝(b0,b1,…,bN-1)，两序列的互相关值为：
图12给出了本申请给出的序列(由调制的时域序列经DFT变换和频域扩展处理后得到的 DMRS序列)的频域平坦度性能。通过图12可以发现80％的序列的频域平坦度值在-4dB以内，可以保证良好的信道估计精度。其中，曲线2为由调制的时域序列经DFT变换和频域扩展处理后得到的DMRS序列。
图13给出了本申请给出的序列(由调制的时域序列经DFT变换和频域扩展处理后得到的DMRS序列)的互相关性能。通过图13可以发现：序列间的互相关值均小于0.8。其中，互相关值越小，抗干扰性能越好。其中，曲线2为由调制的时域序列经DFT变换和频域扩展处理后得到的DMRS序列。
另一种方案为，所述M小于30时，将公式9中的QPSK调制序列作为时域基序列，将时域基序列依次进行DFT变换和频域扩展处理后得到DMRS序列，这样处理可以使得序列和数据经过完全相同的调制和波形发送，因此数据和序列的PAPR/CM性能会很接近。
具体地，rn的取值集合可以有以下几种实现：
在一个实现中，当所述M小于30时，采用如公式9所示的QPSK调制序列作为时域基序列，将时域基序列依次进行DFT变换和频域扩展处理得到DMRS序列。序列[rn]的具体生成的公式为：
然后根据序列[rn]和公式6生成序列[fn]，并将序列[fn]进行频域扩展处理得到DMRS序列[Sk]。其中，rn的取值集合为即 为序列中的元素，序列属于下列所示的序列集合，其中每行表示序列的一种可能取值：

需要注意的是，在实现中发送端可以直接确定序列[Sk]，然后将序列[Sk]映射到Q个子载波上，生成第一信号，也可以先确定序列[fn]，然后通过循环扩展处理得到序列[Sk]，也可以通过其他方式确定序列[Sk]，本实施例对此不做限定。
如图14所示，为本申请实施例提供的一种由公式9中的QPSK调制序列依次进行DFT变换和频域扩 展处理后得到的DMRS序列使用FDSS后的CM性能示意图。所述M为18，分别采用RRC滤波器和三抽头滤波器，DMRS序列的CM性能如图14所示，无论使用RRC滤波器还是三抽头滤波器，DMRS序列的CM性能与数据信号持平。其中，曲线1为经过RRC滤波器且扩展比例为25％的DMRS序列；曲线2为经过三抽头滤波器且扩展比例为50％的DMRS序列；曲线3为经过RRC滤波器和比例为25％的频域扩展的数据信号；以及曲线4为经过三抽头滤波器和比例为50％的频域扩展的数据信号。
图12给出了本申请给出的序列(由QPSK调制的时域序列经DFT变换和频域扩展处理后得到的DMRS序列)的频域平坦度性能。通过图12可以发现80％的序列的频域平坦度值在-4dB以内。其中，曲线1为由QPSK调制的时域序列经DFT变换和频域扩展处理后得到的DMRS序列。
图13给出了本申请给出的两种序列(由QPSK调制的时域序列经DFT变换和频域扩展处理后得到的DMRS序列)的互相关性能。通过图13可以发现：由QPSK调制的时域序列经DFT变换和频域扩展处理后得到的DMRS序列的互相关值均小于0.7，相较于由调制的时域序列经DFT变换和频域扩展处理后得到的DMRS序列具有更优的互相关性能。其中，曲线1为由QPSK调制的时域序列经DFT变换和频域扩展处理后得到的DMRS序列；曲线2为由调制的时域序列经DFT变换和频域扩展处理后得到的DMRS序列。
另一个预设条件为，M大于或等于第一阈值时，A1为非零复数，α1为实数，M1为小于M的最大质数，(k+M1-P1)modM1表示(k+M1-P1)除以M1的余数，Q是M1和E1之和，P1为大于或等于0且小于或等于E1的整数，k属于{0，…，Q-1}；gn为序列[gn]中的元素，序列[gn]为包括M1个元素的序列，gn满足：n的取值为0到M1-1， 其中v＝0或1，u∈{0,1,…,29}。
例如，M大于36时，使用如公式1和公式2给出的频域ZC序列作为DMRS序列。
又例如，M为30时，使用如公式3给出的截断的频域ZC序列作为DMRS序列。
频域扩展前的序列为{X(0),X(1),…,X(M-1)}。
进一步地，根据频域扩展比例进行循环扩充，向左(向前)扩充P个元素，向右扩展E-P(向前)个元素，得到DMRS序列[X(M-P),X(M-P+1),…,X(M-1),X(0),X(1),…,X(M-1),X(0),X(1),…,X(E-P-1)]，具体的公式表达如下：
X(k)＝X((k+M-P)mod M)……公式10
