信号样本 meaning in Chinese
signal sample
Examples
- The so - called automatic recognition of modulation ( amr ) schemes automatically classifies the modulation types from the samples of received signal by abstracting the related features such as amplitude , frequency , and phase , followed by employing proper recognition algorithms based on the fast digital signal processing techniques and advanced computing technology . the result of amr can be used in the following processing blocks such as demodulation , supervision processing and anti - interference processing and so on
所谓调制类型自动识别( amr )是根据接收信号样本提取出振幅、频率和相位的特征参数，然后借助信号处理技术和计算机快速处理能力，采用合理算法进行处理，从而实现对未知已调波调制类型的自动识别，为后继的解调、监控、抗干扰等处理奠定基础。 - It is especially attractive for the downlinks and suppressing intercell mai . when multiuser detector is adapted in blind mode , it usually adopts eignvalue decomposition or singularvalue decomposition of received sample correlation matrix and tracking alrithgms , which result in high computational complexity . at the same time , approximation computation in tracking alrithgms also result in slow convergence
为实现盲自适应检测，通常采用对接收信号样本矩阵进行特征值分解( evd )或奇异值分解( svd )后进行跟踪，由此带来的子空间秩跟踪使得实现复杂度很高；另一方面，在跟踪算法中考虑一些实际情况而作出近似处理，从而引起误差积累和正交性误差，导致每次跟踪开始阶段跟踪速度变慢。
