matlab 实现的小波变换 希望对大家有用(wavelet transform)

this code is help you to draw Fourier Series . with this code you can change some variable and explain what change for education.

The article concerns observing states of the Induction Motor (IM) using a Luenberger observer in the speed servo drive. The movement of the motor and observer roots is analyzed for a variable speed. Following the analysis, a new method for gain evaluation of the IM magnetic flux observer is presented. This structure is extended by including an adaptive speed observer. The functionality of the presented method is proved in simulations using MATLAB Simulink.

Offset quadrature phase-shift keying (OQPSK) is a variant of phase-shift keying modulation using 4 different values of the phase to transmit. It is sometimes called Staggered quadrature phase-shift keying (SQPSK).
