一种信号处理方法及通信芯片结构
本申请要求于2017年7月31日提交中国专利局、申请号为201710640769.3、申请名称为“一种信号处理方法及通信芯片结构”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，具体涉及一种信号处理方法及通信芯片结构。
背景技术
随着移动通信技术的发展，移动终端(例如，手机)需要支持2G、3G、4G(LTE-Advanced)以及未来5G的标准，对2G、3G、4G单载波以及4G连续多载波场景，信号在一个频段或者相邻频段里，在移动终端的芯片中大多采用低带宽的连续时间求和差分模数转换器(CT Sigma-delta ADC)(带宽小于200MHz)用来做接收信号的采样量化处理。对4G频段间非连续载波聚合(Carrier Aggregation，CA)和5G场景，芯片就需要用多个低带宽的模数转换器(Analog-to-Digital Converter，ADC)来进行信号的采样量化。
对于不同CA频段的信号的采样量化，第一种实现方式为：通过接收通道双拼或者多拼的方法对信号进行采样量化，一个接收通道中包括一个CT Sigma-delta ADC；但是采用第一种实现方式时，多个低带宽的ADC已经遇到了芯片的芯片面积和功耗的瓶颈，因此使用第二种实现方式，具体为：采用一个射频模数转换器(Radio Frequency ADC，RFADC)对信号进行采样量化。
采用第二种实现方式时，由于目前RFADC在技术上无法满足既要能支持4G频段间非连续CA和5G场景的大带宽输入，同时又要满足2G场景下的高线性度要求。
发明内容
本申请实施例提供一种信号处理方法及通信芯片结构，具有支持预置窄带宽跨度信号和预置大带宽跨度信号的采样处理通道，使得通信芯片结构既能支持4G频带间非连续CA和5G场景下大带宽输入，又能满足2G场景下的高线性度要求，同时减少通信芯片结构的功耗和面积。

具体实施方式
本申请实施例提供了一种信号处理方法及通信芯片结构，具有支持预置窄带宽跨度信号和预置大带宽跨度信号的采样处理通道，使得通信芯片结构既能支持4G频带间非连续CA和5G场景下大带宽输入，又能满足2G场景下的高线性度要求，同时减少通信芯片结构的功耗和面积。
下面将结合本申请实施例中的附图，对本申请实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本申请一部分实施例，而不是全部的实施例。基于本申请中的实施例，本领域技术人员在没有作出创造性劳动前提下所获取的所有其他实施例，都属于本申请保护的范围。
通信终端需要支持2G、3G、4G以及未来5G的标准，对2G、3G、4G单载波以及4G连续多载波场景，信号在一个频段或者相邻频段里，在移动终端的芯片中大多采用CT Sigma-delta ADC用来做信号的采样量化处理。对4G频段间非连续CA和5G场景，芯片就需要用多个ADC来进行信号的采样量化。对于不同CA频段的信号的采样量化，第一种实现方式如图1所示，4个通道滤波器(Channel Filters)，可以将原始信号分成四路频带信号，包括低频段信号(LB)、中频段信号(MB)、高频段信号(HB)和超高频段信号(UHB)，每路信号通过增益调节模块(Gain Tuning)进行幅度放大，通过混频器(Mixer)将每路信号调制到基带频段，每路信号通过一个低通滤波器(Low Pass Filter，LPF)后，被一个CT Sigma-delta AD进行采样量化，频率综合器(Frequency Synthesizer)为Mixer提供本振时钟，Gain Tuning和LPF由DBB控制，锁相环(Phase Lock Loop，PLL)为CT Sigma-delta ADC提供工作时钟，最终数字基带(Digital Base Band，DBB)得到采样量化后的数据，CT Sigma-delta AD的数量是随通道滤波器数量的变化而变化的。但是随着无线通信下行吞吐需求越来越高，多个CT Sigma-delta AD已经遇到了芯片的芯片面积和功耗的瓶颈。第二种实现方式如图2所示，通过信号合成器(Adder)将四路信号合成为一路，被一个RFADC进行采样量化，Frequency Synthesizer为RFADC提供本振时钟。第二种实现方式相比第一种实现方式，在面积和功耗上都有优势，但是从目前学术界和工业界的RFADC发展情况看，既要能支持4G频段间非连续CA和5G场景的大带宽输入又要满足2G场景下高线性度要求的RFADC还不成熟。
为了解决以上的问题，请参阅图3所示，本申请实施例提供一种通信芯片结构，包括：
数字基带模块301、通道选择模块302、第一采样量化通道303及第二采样量化通道304，第一采样量化通道303用于采样量化处理预置窄带宽跨度信号，第二采样量化通道 304用于采用量化处理预置大带宽跨度信号；

本申请实施例中，由于第一采样量化通道303是用于处理预置窄带宽跨度信号的，而预置窄带宽跨度信号具体可以是2G、3G、4G单载波和4G连续CA场景下的信号，那么第一采样量化通道303需要包括低通滤波单元401和低带宽模数转换单元402，低通滤波单元401用于对输入信号进行滤波处理，从而滤除干扰信号，低带宽模数转换单元402用于对滤波处理后的输入信号进行采样量化处理。

本申请实施例中，输入信号是直接可以被第一采样量化通道和第二采样量化通道进行采样量化处理的信号，在具体实施时，原始信号并非是直接可以用于采样量化的，因此通信芯片结构还包括滤波模块501、增益调节模块502、混频模块503及信号合成模块504，滤波模块501接收原始信号，并对原始信号进行滤波处理，得到至少一路子信号，至少一路子信号中每一路子信号的频段不同，一般可以按照低频段、中频段、高频段和超高频段的规则，滤波处理得到四路子信号。增益调节模块502接收到至少一路子信号，将至少一路子信号发送到通道选择模块302，数字基带模块301控制增益调节模块502的增益调节 幅度，增益调节模块根据增益调节幅度对至少一路子信号进行增益调节，得到输入信号，并将输入信号发送至通道选择模块302，输入信号包括至少一路子输入信号，混频模块503接收通道选择模块发送的输入信号，并将输入信号的频段调制为基带频段，从而方便于第一采样量化通道303的采样量化处理；信号合成模块504接收通道选择模块发送的输入信号后，对输入信号的至少一路子输入信号进行合成，从而方便于第二采样量化通道304的采样量化处理。
可选的，如图5所示，本申请的一些实施例中，滤波模块501包括N个滤波器，增益调节模块502包括N个增益调节单元，通道选择模块302包括N个选择开关，混频模块503包括N个混频器，

本申请实施例中，假设滤波模块501具体包括N个滤波器，那么对原始信号进行滤波处理，得到N路子信号，而每一路子信号都要进行增益调节，因此，增益调节模块502包括N个增益调节单元，对应到通道选择模块303的通道选择功能，通道选择模块303包括N个选择开关，在通道选择模块303选择第一采样量化通道时，一路子信号通过一个选择开关输出到混频模块503中的一个混频器，混频模块中混频器的数量为N个，而第一采样量化通道是分别对输入信号的每一路子输入信号进行采样量化处理的，那么第一采样量化通道中低通滤波单元和低带宽模数转换单元的数量为均N个。
