路由器及其干扰消除装置、方法、及存储介质 技术领域
本发明实施例涉及但不限于通信技术领域,具体而言,涉及但不限于一种路由器及其干扰消除装置、方法、及存储介质。
背景技术
现在几乎每个家庭都拥有电脑,手机等众多的电子设备,网络成为每个家庭不可或缺的一种虚拟物质,我们通过家庭路由器的无线网络来满足日常的上网来获取一些重要的资料,无线性能的好与坏决定我们上网速度与质量,一款性能优秀的路由器能够大大的提高我们的生活与工作的效率。目前路由器会受外部的环境噪声以及可能的内部设备噪声的影响,导致信号的解调质量以及接收灵敏度下降,严重者信号淹没在噪声中,导致接收的信号无法解调;同时,由于主板上的功能较多,各种频率以及信号互相叠加,使得噪声台阶增高,wifi接收到的信号淹没在噪声中,导致信号无法正确的解调。
目前路由器对于主板内的干扰或者噪声都是通过排查主板上的双倍速率(Double Data Rate,简称为DDR)同步动态随机存储器或者高速串行计算机扩展总线标准(Peripheral Component Interconnect express,简称为PCIE)等外设所引起的干扰,对于这些干扰我们能够解决的常用方法基本都是更换频点或者降低DDR的驱动电平等来达到降低或者减弱干扰,但是有些频点确实不能进行更改,一旦进行更改后,性能就会受到很大的影响。对于这些方法需要花费大量的人力物力去进行排查干扰源,最终未必能很完美的进行彻底解决干扰。

具体实施方式
为了使本发明的目的、技术方案及优点更加清楚明白,下面通过具体实施方式结合附图对本发明实施例作进一步详细说明。应当理解,此处所 描述的具体实施例仅仅用以解释本发明,并不用于限定本发明。
实施例一:
为了解决相关路由器受环境噪声和主板噪声的影响,导致接收到的信号在解调过程中出现失真或丢包的问题,本发明实施例提供一种路由器的干扰消除装置。请参见图1,该干扰消除装置具体包括:通信信号接收模块100、干扰信号采集模块110和信号降噪处理模块120。
通信信号接收模块100,设置为接收通信信号,并将通信信号发给信号降噪处理模块120;
需要说明的是,通信信号接收模块100接收到的通信信号包括有用信号和第一干扰信号,其中有用信号的强度强。可以理解的是,有用信号和第一干扰信号混合在一起作为信号降噪处理模块120的输入信号。
干扰信号采集模块110,设置为采集第二干扰信号,并发给信号降噪处理模块120;
应当理解的是,干扰信号采集模块110包括环境干扰信号采集模块和主板干扰信号采集模块中的至少一个,环境干扰信号采集模块设置为采集路由器的环境干扰信号,主板干扰信号采集模块设置为采集路由器内部的主板干扰信号。在一些实施例中,干扰信号采集模块包括环境干扰信号采集模块和主板干扰信号采集模块,第二干扰信号包括环境干扰信号和主板干扰信号。
应当理解的是,环境干扰信号采集模块主要接收环境干扰信号,同时接收到一部分强度较弱的有用信号。上述环境干扰信号与主板干扰信号叠加后产生总的第二干扰信号,干扰信号采集模块110将该第二干扰信号发送给信号降噪处理模块120,使得该第二干扰信号作为信号降噪处理模块120的参考输入信号。
信号降噪处理模块120,根据第二干扰信号对通信信号中的第一干扰信号抵消处理得到降噪用于后的通信信号。
需要说明的是,信号降噪处理模块120包括不限于以下任一种:维纳 滤波器、自适应滤波器以及横向FIR滤波器。
可选的,信号降噪处理模块120包括维纳滤波器时,请参见图2,X(n)为通信信号,Q(n)为干扰信号,Y(n)为输出信号,通过维纳滤波器可使得通信信号中的干扰信号降到最低,从而得到的输出信号为纯净的通信信号。
可选的,信号降噪处理模块120包括自适应滤波器时,自适应滤波器根据第二干扰信号产生第一抽头系数;信号降噪处理模块120根据第一抽头系数对第一时刻通信信号中的第一干扰信号抵消处理,得到第一次降噪后的通信信号;第一次降噪后的通信信号作为负反馈使得自适应滤波器产生第二抽头系数;信号降噪处理模块120再根据第二抽头系数对第二时刻通信信号中的第一干扰信号抵消处理,得到第二次降噪后的通信信号,直到第n次降噪后的通信信号为稳定值时,输出第n次降噪后的通信信号。请参见图3,自适应滤波器的原理为:x1(n)、x2(n)、x3(n)...xN(n)是任一组通信信号,w(n)为自适应滤波器的抽头系数,N为自适应滤波器的阶数,y(n)为输出信号,d(n)是期望信号,e(n)为误差信号,其误差信号e(n)=d(n)-y(n)。自适应滤波器会根据误差信号e(n)的值而自动调节抽头系数w(n),使之适合下一时刻的输入信号,以使输出信号更接近于所期望的信号,直至均方误差达到最小值。通过自适应滤波器的降噪处理输出逐渐接近期望信号的通信信号,即输出的通信信号的纯净度是逐步增加的,直到该纯净度达到一个稳定值。
可选的,信号降噪处理模块120包括横向FIR滤波器时,请参见图4,x(n)、x(n-1)、x(n-2)...x(n-N+1)是同一通信信号的不同延时组成,w(n)为横向FIR滤波器的抽头系数,N为横向FIR滤波器的阶数,y(n)为输出信号,d(n)是期望信号,e(n)为误差信号,其误差信号e(n)=d(n)-y(n)。对于横向FIR滤波器,是根据误差信号e(n)进行自适应的调节抽头系数,使之适合下一时刻的输入信号,以使输出信号更接近于所期望的信号。经过自适应的不断调节,横向FIR滤波器横向FIR滤波器的均方误差会逐步减少,而均方误差没有明显的减少时,这个时候表示滤波器已经收敛到稳定 值,在均方误差最小的情况下,横向FIR滤波器的输出y(n)就是期望d(n)的最优逼近值。最终,通过横向FIR滤波器实现了将每一个通信信号里第一干扰信号降到最低后输出信号,从而降噪后可得到纯净的通信信号。
对于上述路由器的干扰消除装置,可选的,还包括信噪分离模块。信噪分离模块设置为对第二干扰信号中的有用信号进行分离;干扰信号采集模块110将采集到的第二干扰信号通过信噪分离模块发给信号降噪处理模块120。
可选的,上述信噪分离模块包括功分单元501、相位延迟单元503、合路单元502。功分单元501设置为将第二干扰信号分为第一路干扰信号和第二路干扰信号;相位延迟单元503设置为对所述第二路干扰信号的相位延迟180度后得到第二路延位干扰信号,并发给合路单元502;合路单元502设置为对第一路干扰信号中的有用信号进行分离后,发给信号降噪处理模块120。在一些实施例中,请参见图5,合路单元502的输入端与干扰信号采集模块110连接,功分单元501将从干扰信号采集模块110接收到的干扰信号分为两路,一路为第一路干扰信号,另一路为第二路干扰信号。第一路干扰信号进入合路单元502,第二路干扰信号进入相位延迟单元503,通过相位延迟单元503将第二路干扰信号相位延迟单元180度后发给合路单元502。应当理解的是,第一路干扰信号和第二路干扰信号均包括有用信号,相对第二干扰信号,有用信号的强度较弱,第二路干扰信号通过相位延迟单元180度后,由于有用信号具有规律性,可将有用信号转变成负的有用信号,从而得到第二路延位干扰信号。再通过第一路干扰信号和第二路延位干扰信号在合路单元502里进行叠加,以抵消有用信号从而得到纯净的第二干扰信号。
可选的,上述信噪分离模块还包括放大单元504,第二路延位干扰信号通过放大单元504进行放大处理后,发给所述合路单元502。
请参见图6,功分单元501将从干扰信号采集模块110接收到的第二 干扰信号分为两路,一路为第一路干扰信号,另一路为第二路干扰信号。第一路干扰信号进入合路单元502,第二路干扰信号进入相位延迟单元503,通过相位延迟单元503将第二路干扰信号相位延迟单元180度后进入放大单元504,再通过放大单元504的发大处理后发给合路单元502,最后通过合路单元502可以将第二干扰信号中的有用信号幅度降到最低后发给信号降噪处理模块120。
