ZeroForcing MIMO BPSK BER

(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Simulink工具编写代码(S-Function方式)，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。 ((1) in certain wireless channel, the Doppler frequency shift will be caused by wireless channel output signal aliasing. Please describe the resulting aliasing of a variety of reasons (2) wireless channel Doppler spectrum there is a classical spectrum (classic spectrum), please explain such a spectral shape of the mechanism (3) Please use Simulink tools for writing code ( S-Function mode), resulting in a single Path Rayleigh channel, the Doppler spectrum for the classical spectrum, including mobile rate of 120km/h. And please answer: prove that they used computer-generated classical spectrum is correct possible ways.)

clustering ---uses a kmeans method(clustering---uses a kmeans method)

说明：  上采样和内插，使得系统中同时出现的窄带信号和宽带信号能够采用适合本信号的采样率(On sampling and interpolation, making the system at the same time, the narrowband signals and broadband signals can be used for the signal sampling rate)

Matlab for engineering programs.

说明：  matlab程序例子在教学中的应用非常有用而且我很喜欢(matlab program examples in teaching that is useful very much so that I like it so much )
