2) Residua Error Rate 剩余误差率 3) residual error 剩余误差 1. At present,constant modulus algorithm (CMA) is widely used,but it has disadvanta- ges that the convergence speed is slow and the residual error is large. 目前,常数模算法(constant modulus algorithm,CMA)应用非常广泛,但它存在收敛速度慢,剩余误差大的缺点。 2. The influence of systems error,random error and truncation error of numerical integration on residual error are anelyzed. 提出了利用遥测的过载、俯仰角信息和光测的坐标联合计算弹道关机段速度的方法 ,从遥测结果的系统误差、随机误差和数值积分的截断误差三方面对剩余误差的影响进行了精度分析 ,并给出了速度精度的算 3. Though the algorithm overcomes the shortcoming of conventional CMA’s larger residual error after convergence and ‘stop-and-go’ algorithm’s fixed parameters, the convergence rate is slower. 文献[1]提出了一种适用于PAM、QAM通信系统的盲均衡算法——MMA,该算法虽然克服了CMA收敛后剩余误差大和stop-and-go等算法有待定参数的缺点,但是它的收敛速度比较慢,改进算法1对MMA进行了改进,加快了算法收敛的速度。 4) residual errors 剩余误差 1. In order to guarantee ultralow sidelobe level of solide-state active phased array antenna,there is very strict requirement on the control of channel calibration residual errors and on amplititute-phase consistency of multiple channels. 为实现有源相控阵天线的超低副瓣性能,对通道校准的剩余误差控制,以及通道间的幅相一致性提出了更高的要求。 5) automatic frequency control 频率自动微调 6) residential frequency modulation 剩余调频
