设载波频率为20Hz，信息速率为2Baud,用MatLab画出QPSK信号波形。-Carrier frequency set to 20Hz, the information rate of 2Baud, using MatLab draw QPSK signal waveform.

基于感应电机的转子电阻预估计的无速度传感器的直接转矩控制技术。控制电机的一种很先进的控制方法。-Based on the induction motor rotor resistance of the pre-estimation of the speed sensorless direct torque control technique. Motor control a very advanced control methods.

In this simulink model , BPSK modulation and demodulation is simulated .A square root raised cosine pulse shaped signal is modulated and given as input to the demodulator.The received signal is demodulated and given to the detector where it is matched filtered and down-sampled .The effects of symbol timing offset can be seen by varying the phase of down-sampling operation.The signal transmitted is recovered at the detector output.-In this simulink model , BPSK modulation and demodulation is simulated .A square root raised cosine pulse shaped signal is modulated and given as input to the demodulator.The received signal is demodulated and given to the detector where it is matched filtered and down-sampled .The effects of symbol timing offset can be seen by varying the phase of down-sampling operation.The signal transmitted is recovered at the detector output.
