每个BS270可以服务一个或多个分区(或区域)，由多向天线或指向特定方向的天线覆盖的每个分区放射状地远离BS270。或者，每个分区可以由用于分集接收的两个或更多天线覆盖。每个BS270可以被构造为支持多个频率分配，并且每个频率分配具有特定频谱(例如，1.25MHz，5MHz等等)。
分区与频率分配的交叉可以被称为CDMA信道。BS270也可以被称为基站收发器子系统(BTS)或者其它等效术语。在这样的情况下，术语“基站“可以用于笼统地表示单个BSC275和至少一个BS270。基站也可以被称为“蜂窝站”。或者，特定BS270的各分区可以被称为多个蜂窝站。
如图1-2中所示，广播发射器(BT)295将广播信号发送给在系统内操作的移动终端100。如图1-1中所示的广播接收模块111被设置在移动终端100处以接收由BT295发送的广播信号。在图1-2中，示出了几个全球定位系统(GPS)卫星300。卫星300帮助定位多个移动终端100中的至少一个。

实施例二
基于前述的实施例，本发明实施例提供一种信息处理方法，应用于终端，该信息处理方法所实现的功能可以通过终端中的处理器调用程序代码来实现，当然程序代码可以保存在计算机存储介质中，可见，该终端至少包括处理器和存储介质。
图2为本发明实施例二信息处理方法的实现流程示意图，如图2所示，该信息处理方法包括：
步骤S201，采集单元负责采集来自空间环境的音频信息，以一定采样率和位深进行采样和量化；
步骤S202，第一获取单元中的获取模块负责采集当前移动终端在空间的x，y，z三轴信息，传输给第一获取单元中的计算模块，计算模块通过 反三角函数，计算出当前移动终端偏移垂直方向的角度θ,传输此角度值θ发送给第一确定单元或第二确定单元。
步骤S203，第二获取单元获取原始的声压级差；
步骤S204，第三获取单元获取原始的相位差；
步骤S205，所述第一确定单元根据所述角度θ、终端录入声音采集部件之间的距离测量值、声波在介质中的传播的速度c确定当前的声压级差；
步骤S206，所述第二确定单元根据所述角度θ、终端录入声音采集部件之间的距离测量值、声波在介质中的传播的速度c确定当前的相位差；
步骤S207，所述第一补偿单元根据所述当前的声压级差与所述原始的声压级差对所述音频信息进行声压级的补偿。
步骤S208，所述第二补偿单元根据所述当前的相位差与所述原始的相位差对所述音频信息进行相位的补偿。
本发明实施例中，根据此角度θ以及录入音频信号的相位差、声压级差，并根据声音在空气中的传播公式以及出厂前对移动终端录入MIC之间的距离测量值，对各录入声道(即各个MIC的音频信息的声压级和相位)的进行适当的补偿，使其从偏移的位置回归到垂直。
具体补偿的过程是这样的：假设终端录入MIC的距离为d＝2r，两个录入MIC在终端两侧端点分布，假设声源(假设声源为点声源)到终端第一麦克风(MIC1)距离为D，水平夹角为0°的位置发出频率为f的纯音，则到第二麦克风(MIC2)的距离为D+d，其中d不等于0，换句话说，第二麦克风距离声源的距离比第一麦克风距离声源的距离要远，声波在空气中的传播的速度为c，MIC1录入的信号比MIC2录入的信号声压级要强、相位要提前，具体计算公式如下：
声压级差＝20lgd＝20lg2r；
相位差＝d/2πfc＝r/πfc；
当终端偏移了角度θ后，参见图1-4，则声源到MIC1的水平夹角为-θ,到MIC2的水平夹角为θ，MIC1远离声源，而MIC2接近声源；具体计算公式如下：
声压级差＝20lg d’＝
Figure PCTCN2016082917-appb-000003
相位差＝d’/2πfc＝
Figure PCTCN2016082917-appb-000004
