本公开基于2021年06月10日提交的发明名称为“一种数据传输方法、装置、存储介质及电子装置”的中国专利申请CN202110654381.5，并且要求该专利申请的优先权，通过引用将其所公开的内容全部并入本公开。
本公开实施例涉及通信领域，具体而言，涉及一种数据传输方法、装置、存储介质及电子装置。
数据传输对于任何形式的通信来说都必不可少，只有当信息的发送方和接收方都能够理解编码机制的时候压缩数据通信才能够工作。
数据压缩是指在尽可能少丢失信息的前提下，缩减数据量以减少存储空间，提高其传输、存储和处理效率的一种技术方法，或按照一定的算法对数据进行重新组织，减少数据的冗余和存储的空间。由于可以帮助减少如硬盘空间与连接带宽这样的昂贵资源的消耗，所以压缩非常重要，然而压缩需要消耗信息处理资源，这也可能是费用昂贵的。所以数据压缩机制的设计需要在压缩能力、失真度、所需计算资源以及其它需要考虑的不同因素之间进行折衷。
随着无线通信系统的带宽或者天线数的增加，数据传输速率将按照正比例增加，将极大的增加设备的硬件成本和实现难度。因此，有效的数据压缩和传输方法是通信系统必不可少的一部分。
基于以上原因，开放无线接入网络(open radio access network，简称为ORAN)协议规定了数据压缩方法和IQ数据封装格式。数据压缩方法包括块浮点数(block floating point，简称为BFP)压缩、归一化(block scaling)压缩、μ律(μ law)压缩、波束空间(beamspace)压缩、调制(Modulation)压缩和资源单元(resource element，简称为RE)选择性发送(selective RE sending)压缩六种压缩方法；IQ数据封装格式说明了压缩后的IQ数据和压缩指数的排列方式。
在5G基带信号处理过程中，对数据进行傅里叶变换或快速傅里叶逆变换、功率控制等数字信号处理是必不可少的。在当前的常用方案中，这些信号处理过程往往需要对数据进行缩放处理以降低资源消耗并伴随产生相应的信号处理缩放指数。安全实时传输控制ORAN协议虽然说明了数据压缩方法和压缩指数的传输方式，但指数位宽被限定为4bit，且未明确上述数字信号处理过程中的信号处理缩放指数的传输方式，从而无法直接实现有效的数据传输。
针对相关技术中ORAN协议未明确信号处理缩放指数的传输方式，导致无法直接实现有效的数据传输的问题，尚未提出解决方案。

步骤S100、从前级信号处理过程获取待压缩的IQ数据I和Q、前级数据压缩指数s_fac、压缩控制指令和ORAN封装指令，其中IQ数据位宽为W bit，s_fac表示前级信号处理过程中数据的缩放位数，压缩控制指令确定压缩点数N(即压缩后的数据为N bit，N＜＝W)，ORAN协议中数据封装有两种大小端排列方式，ORAN封装指令控制具体的大小端排列。获得上述相关数据和信息后进入步骤S101。
步骤S101、根据压缩指令以RB(resource block，一个RB对应12对IQ数据为单位进行N点压缩)为单位进行数据压缩，压缩算法可以采用ORAN协议中的BFP压缩和归一化压缩，具体压缩算法参见ORAN协议，完成当前数据组压缩处理得到压缩指数c_fac和压缩数据后进入步骤S102。
步骤S102、以RB为单位对缩放指数s_fac和压缩指数c_fac求和得到合并后的指数exp_temp，缩放指数s_fac由步骤S100得到，每个RB的压缩指数c_fac由步骤S101计算得到，完成当前RB的指数合并后进入步骤S103。
步骤S103、根据合并后的指数exp_temp计算当前RB发送时的指数exponent和数据移位因子shift，当exp_temp＞15时，exponent＝15，shift＝exp_temp-15；当15＞＝exp_temp＞＝0时，exponent＝exp_temp，shift＝0；当exp_temp＜0时，exponent＝0，shift＝exp_temp。跳转到步骤S104。
步骤S104、根据步骤S103计算得到的数据移位因子shift对步骤S101得到的当前RB压缩后的Nbit IQ数据dataI和dataQ进行移位并进行防溢出处理后得到当前RB的发送数据I_tx和Q_tx。数据移位过程为当shift＞＝0时，dataI和dataQ分别左移shift位；当shift＜0时，dataI和dataQ分别右移-shift位。防溢出处理可以采用但不限于的方法为当左移后的数据大于N bit有符号数据的最大值2^(N-1)-1时，左移后的数据置为2^(N-1)-1，否则不做改变。对当前RB所有12对压缩后的数据进行移位和防溢出处理后进入步骤S105。
步骤S105、重复步骤S101～步骤S104得到所有RB的发送数据I_tx和Q_tx及发送指数exponent后，在ORAN封装指令的控制下按照图6和图7所示的ORAN协议下的数据封装格式进行数据封装并发送。
图8是根据本实施例的基于ORAN协议的数据接收的流程图，如图8所示，包括如下步骤：
步骤S200、接收发送端发送的数据、数据封装指令、解压缩算法、解压缩点数N、解压缩后数据位宽M等信息，并根据封装指令指定的大小端格式解析数据得到每RB的压缩数据I_tx和Q_tx以及发送指数exponent，进入步骤S201。
步骤S201、找出步骤S200中所有RB的发送指数exponent的最大值expmax并计算最大压缩指数c_facmax＝M-N，进入步骤S202。
步骤S202、计算所有RB的信号处理缩放指数s_fac＝expmax-c_facmax，进入步骤S203。
步骤S203、以RB为单位计算解压缩指数。根据步骤S200得到的每个RB的发送指数exponent和步骤S202得到的所有RB的信号处理缩放指数s_fac计算每个RB的解压缩指数c_fac＝exponent-s_fac，进入步骤S204。
步骤S204、根据步骤S203得到的解压缩指数c_fac对当前RB数据进行解压缩，解压缩算法可采用ORAN协议中的BFP和归一化解压算法，进入步骤S205。
步骤S205、重复步骤S203和步骤S204完成所有RB数据解压缩完成数据和信号处理缩放指数的接收并用于后续信号处理。
本实施例，克服了现有ORAN协议无法直接传输信号处理缩放指数的问题，提出了一种具体的高精度数据传输方案，该方案在保证传输精度的基础上可以有效传输FFT/IFFT变换、功率控制等数字信号处理和数据压缩过程中的数据缩放指数，实现了满足ORAN协议的数据传输。通过应用本方案可以在满足ORAN协议的前提下提升信号处理和压缩过程中动态范围和资源配置的灵活性，可以有效减少存储空间，提高其传输、存储和处理效率。
