说明： 8. 单径瑞利信道中的四发四收V-BLAST：
(1) 请设计一种具体的导引辅助的信道估计方法，用Simulink进行仿真，测量16QAM调制时的误码率性能。画出比特信噪比与信道估计均方误差的关系曲线，画出比特信噪比与误码率的关系曲线。
(2) 计算所设计方案的频谱效率是多少，单位为bit/Hz/s。(8. Four transmit four receive v-blast in single-path Rayleigh channel:
(1) please design a specific navigation-assisted channel estimation method and conduct simulation with Simulink to measure the bit error rate performance of 16QAM modulation.The relation curve between the bit signal-noise ratio and the mean square error of channel estimation is drawn, and the relation curve between the bit signal-noise ratio and the bit error rate is drawn.
(2) calculate the spectral efficiency of the designed scheme in bit/Hz/s.)

IFAC-WC2011-Final_Submission
In semi-active suspension control, comfort and road holding are two essential but confl icting performance objectives. In a previous work, the authors proposed an LPV formulation for semi-active suspension control of a realistic nonlinear suspension model where the nonlinearities (i.e the bi-viscous and the hysteresis) were taken into account an H/LPV controller to handle the comfort and road holding was also designed.
