strech
去斜率(strech)参考信号与回波信号混频后得到中频输出信号S(t)=Aexp(j*2*pi*f0*t+phase)
其中f0与回波延时的关系为:
f0=k*delay_t
K为线性调频斜率,delay_t为回波延时
将s(t)采样,FFT变换即可得到目标距离与频谱的关系。
Strech 信号测距
输入混频后的中频信号(图一),经采样及FFT变换得到频谱(图二)
再根据频谱与距离的关系式R=Tcf/2B显示出距离(图三)
(Go slope (strech) obtained after the reference signal and the echo signal mixer IF output signal S (t) = Aexp (j* 2* pi* f0* t+phase) f0 and echo delay relationship: f0 = k* delay_t K chirp slope, delay_t the echo delay sampling s (t), the FFT transform to the target distance spectrum of relations. Strech signal ranging input mixer IF signal (Figure 1), sampling and FFT transform spectrum (Figure 2) according the the spectrum distance relationship R = Tcf/2B shows the distance (Figure 3))

多天线系统小区用户最佳预编码顺序的确定.介绍了一种在实际下行广播信道中采用脏纸编码(DPC)设计系统的方法,其
中基站发送端为多天线,接收端为单天线。主要的目标是在下行信道中满足每个用户的最小
速率要求和最大误码率要求的条件下最小化总体的传输功率(Cell users the best pre-coding sequence to determine a multi-antenna system. Describes an actual downlink broadcast channel using dirty paper coding (DPC) design system, wherein the multi-antenna base station transmit side, the receiving terminal as a single antenna. The main goal is to meet the conditions required by the minimum rate and maximum bit error rate of each user to minimize the overall transmission power in the downlink channel)
