Long-distance intelligent safety precaution system consists of spot decoder, video matrix controller and protective central computer etc. It functions as an intelligent, all-round safeguard to the important manufacture place from a long-range. 远程智能安全防范系统由前端解码器、电视矩阵控制器、防范控制中心计算机等各子系统的构成,具有对重要生产场所进行远程、智能及全方位的安全防范监控功能。
The new decoder was designed on the basis of ZF idea. At the receiver, a transformed matrix was constructed and the time variable channel matrix was multiplied. It was a diagonal matrix to remove ISI completely. 新解码器基于ZF思想设计,在接收端构造一变换矩阵,作用该矩阵于时变信道矩阵,使之对角化而达到消除ISI影响的目的。
On the basis of the analysis, it proposed the input decoder algorithm and the circuit implementation. And the paper also designed current switch drivers for the nmos and pmos current source matrix. 在此基础上,提出了输入解码电路的算法以及实现电路,并分别针对NMOS和PMOS电流源矩阵设计了电流源开关驱动器。
For the second kind of decoder, we construct a transformed matrix using the ZF idea and act this matrix on the received signal vector to result in a diagonal matrix thereby eliminating the influence of ISI. 方案二,基于ZF思想,构造一变换矩阵,作用该矩阵于接收信号矢量使之对角化,从而达到去除符号间干扰影响之目的。
