图2为一种多载波宽带信息能量同传发送系统具体实施例结构示意；如图2所示，在本具体实施例中，信号管理控制系统包括：信道参数获取单元，优化算法处理单元，预分配参数单元；
信号管理控制系统基于信道质量参数，匹配最优化算法，动态对基带信号中的信息信号数据流和能量信号数据流进行载波、功率和频谱的预分配，并生成预分配参数集的具体实施过程如下：
信号管理控制系统的信道参数获取单元获取信道质量参数：
优化算法处理单元，根据预设的优化目标和约束条件对能量信号和信息信号进行优化；预设的优化目标涉及：能量信号的载波个数、功率，以及信息信号的信息传输速率；约束条件涉及：接收机所采集功率大于等于接收机所处工作模式所需的最低功率、子载波上的能量信号功率之和小于等于能量信号的总功率、每个子载波频段上的平均功率谱密度小于等于一个既定的参数值、子载波上的信息信号功率之和小于等于信息信号的总功率。
在本具体实施例中，优化算法处理单元的具体优化过程包括如下步骤：
假设发射端基带信号总功率为P,分配于信息基带信号的总功率和能量基带信号的总功率分别为PI和PE，则PI+PE＝P；信号总载波集为Sc，Sc＝ScE∪ScI，其中，ScE为能量信号子载波集，ScI为信息信号子载波集；接收端采集到的能量为Q，即有Q＝βPE，β是能量效率系数；信道参数向量h，其中，h＝[h1,h2……hN]T；总载波数为N，分配于信息信号的载波数和能量信号的载波数分别为NI和NE，则N＝NI+NE。信息基带信号到信息符号和能量基带信号的能量符号分别为SI(n)和SE(n)，n＝1，2,...,m；m≤N；其中：

SI1～SIm分别为信息基带信号中的第1至第m个的信息符号，SE1～SEm分别为能量基带信 号中的第1至第m个的能量符号,用E[S2 I(n)]和E[S2 E(n)]分别表示信息信号和能量信号的能量。因此，接收端采集到的功率Q可用下述关系式表示:
Q＝<h,E[S2 E(n)]>，i＝1…NE，即
Figure PCTCN2015075351-appb-000002
能量信号的功率PE可用下述关系式表示:
Figure PCTCN2015075351-appb-000003
可根据接收端工作所需的最少能量和信道反馈信息，对信息基带信号和能量基带信号的功率、载波和频谱进行分配优化。接收端工作所需的最低功率应当理解为所述接收端多种工作模式所需的最低功率，例如：当接收端处于非充电模式时，接收端工作所需最低功率可以是接收端电路运行所需最低功率；当接收端处于充电模式时，接收端工作所需最低功率可以是接收端电路运行所需最低功率和充电所需功率之和。
在本具体实施例中，优化算法处理单元包括第一优化处理单元和第二优化处理单元，所述第一优化处理单元基于第一优化参数集，根据第一优化目标和第一约束条件集来确定第一基带信号的第一预分配参数集；所述第二优化处理单元基于第一预分配参数集和第二优化参数集，根据第二优化目标和第二约束条件集来确定第二基带信号的第二预分配参数集。
在本实施例中，第一基带信号为能量基带信号，第一优化目标涉及：使第一约束条件集成立的情况下，能量信号载波个数NE最小和能量信号的总功率PE最小；
所述第一约束条件集涉及：1、接收端所采集功率Q大于等于接收端工作所需的最低功率Pmin，即Q≥Pmin；2、发射端子载波上的能量信号功率之和小于等于基带信号中能量信号的总功率；3、每个子载波频段上的平均功率谱密度小于等于一个既定的参数值A,即满足E[S2 E(n)]/B<A，其中，B每个子载波上的信道带宽。
所述第一优化参数集包括以下参数：能量信号子载波集ScE、接收端工作所需最低功率Pmin、每个子载波上的信道带宽B、每个子载波上的平均功率谱密度A和信道参数向量h。
所述第一预分配参数集包括以下参数：能量信号子载波分配集、能量信号功率分配集和能量信号总功率PE。
第二基带信号为信息基带信号，第二优化目标涉及：使第二约束条件集成立的情况下，信息传输速率R最大化；第二约束条件集涉及：子载波上的信息信号功率之和小于等于信息信号的总功率PE。
第二优化参数集包括以下参数：信息信号子载波集、信息信号子载波数NI和信道参数向量h，其中，h＝[h1,h2……hN]T。
所述第二预分配参数包括以下参数：信息信号功率分配集和信息信号子载波分配集。
综上所述，对下列优化问题求解可得出系统预分配参数集。
第一优化处理单元根据下列第一优化目标和第一约束条件集即可得出第一预分配参数集：
min_{h,ScE,Pmin,B,A}PE,NE；其中，{}中的元素所表示为第一优化参数；

s.t.(下述为第二约束条件)
Figure PCTCN2015075351-appb-000005
为进一步解释优化过程的工作原理，下面结合以具体求解方式进行说明。
第一优化处理单元求解步骤举例如下，包括步骤S1-S4：
S1.初始化NE＝1，子载波集合ScE＝Ф(Ф为空集)；
S2.先找到一个能量信号子载波分配集ScE＝{Sci},i＝1,2,…,NE，对应的能量信道参数向量为h E＝{hi},i＝1,2,…,NE，并可通过优化算法(例如注水算法)使得在第一约束条件集成立的情况下，接收端所采集到的功率最大化。具体的，算法如下：
子步骤S21：
Find ScE＝{Sci}，i＝1…NE；
s.t.
max Q，Q≥Pmin；
Figure PCTCN2015075351-appb-000006
E[S2 E(n)]/B≤A,n＝1,2,...,NE。
子步骤S22：通过S21可以找到多个集合，选择最优能量信号子载波集ScE *＝argmin PE，其中，argmin PE表示使PE取得最小值时的参数情况；同时确定最优能量信号功率分配集{E*[S2 E(n)]}和接收端最优采集功率Q*＝<h,E *[S2 E(n)]>，n＝1,2，…，NE。
S3.若步骤S2没有解，则令NE＝NE+1，并令ScE＝Ф，重新循环步骤S2和S3。
S4.若步骤S2有解，则ScE *确定，NE确定，PE确定。
第二优化处理单元求解步骤举例如下，包括步骤S5：
S5.当最优能量信号子载波集ScE *确定，那么相应的信息信号子载波集ScI也得到了，ScI＝{Sci}；信息信号子载波数NI＝N-NE；对应信息信道参数向量h I＝{hi}；其中，i＝1,2，…，NI。
优化系统信息传输速率问题，求解过程如下：
max_{h,ScE *,ScI}R
s.t.
Figure PCTCN2015075351-appb-000007
可求解确定最优信息信号功率分配集{E*[S2 I(n)]}和最优信息信号子载波集ScI *,最终得到最优信息传输速率R*＝argmax R，其中，n＝1,2，…，NI。
其中，R*＝argmax R具体表达式为：
Figure PCTCN2015075351-appb-000008
其中，n＝1,2，…，NI，N0为噪声功率密度参数。
经上述优化得到第一预分配参数集和第二预分配参数集。
预分配参数单元，其用于根据优化算法处理单元的优化结果生成预分配参数集，预分配参数集包括信息基带信号预分配参数集和能量基带信号预分配参数集；信息基带信号预分配参数集包括：信息信号功率分配集、信息信号子载波分配集；能量基带信号预分配参数集包括：能量信号子载波分配集；能量信号功率分配集；能量信号总功率。
在本实施例中，基带信号产生单元包括信息基带信号产生单元和能量基带信号产生单元，能量基带信号产生单元根据能量基带信号预分配参数集中的能量信号功率分配集、能量信号总功率对能量基带信号数据流的功率进行分配，并根据能量信号子载波分配集将子载波分配信息添加至对应的能量基带信号数据流的帧头；信息基带信号产生单元用于根据具体传输需求生成信息基带信号，根据信息信号功率分配集对信息基带信号数据流的功率进行分配，并根据信息信号子载波分配集将子载波分配信息添加至对应的信息基带信号数据流的帧头；由基带信号产生单元产生的信息基带信号为串行的高速率信息流，能量基带信号为串行的高功率能量流。
在本实施例中，编码单元包括信息基带信号编码单元和能量基带信号编码单元；信息基带信号编码单元对信息基带信号进行卷积编码；能量基带信号编码单元对能量基带信号进行正交编码。为保护基带信号、提高系统误码性能，需对两路基带信号分别进行高效编码，其中，信息信号中包含的是更有用的数据，因此需要通过一些高可靠性的编码方式进行编码，而能量信号只需可识别可发射即可，所以能量信号的编码方式可以相对简单。
将经过编码单元编码后的信息基带信号和能量基带信号送入串并行转换单元进行串并转换输出并行的数据流；为了进行多载波和宽带方式的调制，必须将串行高速率信息流转换为并行的低速率信息流，将串行的高功率能量流转换为并行的低功率能量流。
在本具体实施例中，映射单元基于数据流中能量基带信号和信息基带信号的帧头中的功率分配信息、子载波分配信息，根据预分配参数集，对并行的数据流中的信息基带 信号和能量基带信号进行相应的载波调制预分配。
在本实施例中，调制单元包括信息基带信号调制单元和能量基带信号调制单元。信息基带信号调制单元根据载波调制预分配的结果，对信息信号流进行信息调制，调制到合适通带发送的信号形式，搬移到预设的频段。因能量基带信号的平均功率谱密度(PSD)有可能会超出安全标准，因此，在本实施例中，能量基带信号调制单元对能量基带信号先进行频谱扩展调制以降低平均功率谱密度，再用预设的子载波对能量基带信号进行调制。在本实施例中，能量基带信号调制单元包括依次连接的脉冲成形滤波模块、扩频模块和混频模块。能量基带信号先经过脉冲成形滤波模块进行脉冲成形处理，并由扩频模块通过扩频码对能量基带信号扩频，再送入混频模块用预设的子载波进行上变频处理。经调制处理后的信息信号和能量信号经过并串行转换单元的并串行转换得到串行的数据流，送入天线单元进行发送。
本实施例中，调制单元与并串行转换单元之间还设置有插入保护间隔单元，插入保护间隔单元通过在信息基带信号和能量基带信号中加入保护前缀，例如循环前缀，可以防止符间干扰。
本实施例中，优选的，将能量基带信号作为第一基带信号，将信息基带信号作为第二基带信号，在对能量基带信号进行优化的基础上，再对信息基带信号进行优化，能够保证接收机所采集功率达到相应工作模式所需的最低功率，保障接收机正常工作，大大增强了系统的稳定性和可靠性；通过对信息基带信号的优化，使功率进一步得到合理分配，通信速率第一步提高，系统的性能进一步提升。
