ofdm系统设计，采用qpsk调制，可以轻松改变信道条件，比较研究，是非常方便的工具，我用了很多次了，很不错哦！！！(ofdm system using qpsk modulation, you can easily change the channel conditions, comparative study, it is very convenient tool, I use a lot of times, very good, oh! ! !)

A semi blind technique for estimating the carrier frequency offset in OFDM communication systems is presented in this paper. The fractional and integer frequency offsets are esti-mated by employing a few null subcarriers in the rst OFDM symbol in a frame. While the conventional null subcarrier based methods estimate the offset by a single global search, the proposed method employs a two stage estimator, which greatly minimize the computational complexity.

The Reaction Wheel Pendulum is a physical pendulum with a symmetric disk attached to the end which is free to spin about an axis parallel to the axis of rotation of the pendulum. The disk is actuated by a DC-motor and the coupling torque generated by the angular acceleration of the disk can be used to actively control the system. in this simulation We show that the system is locally feedback linearizable by a local diffeomorphism in state space and nonlinear feedback. in this simultion q1 is the pendulum angle, q2 is the disk angle,
taoh is the motor torque input
