预分选 meaning in English
pre-sorting
Examples
- The adaptive front - end has the adaptive ability for the magnitude and frequency of input signals . it can prefilter for the input signals , eliminate the useless signals , and improve the dynamic range of receiver system . it can lessen the burden of digital signal processing in the back - end of receiver , and improve the performance of receiver system
自适应接收机前端对输入信号有自适应能力? ?频率自适应和幅度自适应,这样的前端就可将系统的接收中心频率和带宽自适应到输入信号的频率和带宽,其实就是对输入信号进行一次预分选、预滤波,剔除对接收系统毫无作用的信号;同时对大信号自动减小增益,对小信号增加增益,提高系统的动态范围;而且可以对干扰信号进行压制。 - In this dissertation , several technology problems of pulse trains deintrleaving algorithms are dealt with , they are presorting techniques based on coherent processor , probabilistic neural network deinterleavers , adaptive data association methods for pulse trains analysis and deinterleaving , signal processor designing issues . the research is focused on real time processing . the coherent processor is a crucial technique for real time presorting
