这是描述了LTE上行链路

设计了镜像滤波器opt_filter函数来实现子带分解与合成。取N=256， nbands=16，调用滤波器函数完成子带分解与合成-Mirror filters are designed to achieve opt_filter function subband decomposition and synthesis. Take N = 256, nbands = 16, call the filter function and achieve Synthesis Subband Decomposition

因特殊的业务需要，某些电话交流需要在第三方的监视下进行，假定某电话交流由甲乙丙三方发起，丙为监听控制方，当甲开始说话时，丙可以不允许乙听，并且开始录音，当甲说完时，丙确定是否可以让乙听，如可以。给乙放录音，当乙说话时，重复以上操作。-because of special operational needs, some telephone exchanges in the surveillance of third parties under the assumption that a telephone exchange was launched by the tripartite B, and C to monitor the controlling party, began to speak when the A, B C can not listen, and began recording at the end when A and C to determine whether or not they can B listen, if we can. B recordings to release, when the B words, to repeat the operation.
