QPSK
数字调制就是把数字基带信号的频谱搬移到高频处，形成适合在信道中传输的带通信号。基本的数字调制方式有振幅键控（ASK）、频移键控（FSK）、绝对相移键控（PSK）、相对（差分）相移键控（DPSK）。在接收端可以采用想干解调或非相干解调还原数字基带信号。
(Digital modulation is the spectrum shifting to high frequency digital baseband signals, suitable for the formation of bandpass signal transmission in the channel. Digital modulation basic amplitude keying (ASK), frequency shift keying (FSK), the absolute phase shift keying (PSK), relative (differential) phase shift keying (DPSK). At the receiving end can be used to dry the demodulation or non coherent demodulating the digital baseband signal.

本文所提方法的优越性.(The decoupling Smith control method is presented for multi-input-multi-output system with time-delays
which are often encountered in practical engineering. A new method for designing the decoupler based on the adjoint
matrix of the multivariable system model with time-delays is proposed. By analyzing the amplitude-frequency and phasefrequency
characteristics of the decoupled model, the decoupled model is reduced to a first-order model with time-delay.
According to the closed-loop characteristic equation of Smith predictor structure, a PI controller is developed by using the
principle of pole assignment for Butterworth filter. Sufficient and necessary conditions for robust stability are derived for
adaptive and multiplicative uncertainties commonly occurred in practice. Simulation results show the superiority of the
proposed method.)
