Doppler-spectrum-of-radio-channel
1. 关于无线信道的多普勒谱,请回答以下问题:
(1) 在某些无线信道中,多普勒频移会引起无线信道输出信号的混叠。请清楚的描述产生混叠的各种原因;
(2) 无线信道中的多普勒谱有一种经典谱(classic spectrum),请解释产生这种谱形状的机理;
(3) 请用S-function产生一单径瑞利信道,其多普勒谱为经典谱,其中移动速率为120km/h。并请回答:证明自己用计算机产生的经典谱是正确的可能方法。
(Doppler spectrum of radio channel 1, please answer the following questions
(1) In some wireless channel, radio channel Doppler shift will cause the output signal aliasing. Please clearly describe aliasing for various reasons )
