Bci can provide a new communication option that does not depend on peripheral nerves and muscles for those with neuromuscular impairments , and might also give those without disabilities a supplementary control channel or a control channel useful in special circumstances 它可以为神经肌肉损伤患者提供一种不依赖正常的外围神经和肌肉输出通道的新的通讯工具,也可以为正常人提供辅助控制通道或在特殊环境下的控制通道,因此具有巨大的社会价值和应用前景。
Hsupa ( high speed uplink packet access ) is the new technique of r6 , first in this thesis , the hsupa physical layer is introduced in detail . then base on the physical layer technique characteristic , according to the 3gpp simulation requirements and system simulation requirements , the hsupa downlink and uplink can be constructed by using matlab . then the data channel and control channel can be simulated , so the channels performance can be realized , provide the results can be provided to the system simulation , these ground the future practical applications Hsupa ( highspeeduplinkpacketaccess ) ? ?高速上行分组接入就是r6版本中的新技术,本文首先详细介绍了hsupa物理层的技术特征,然后以其技术特点为依据,按照3gpp的仿真需求和系统级的仿真需求,使用matlab构建hsupa的上下行物理层链路,对其数据信道和控制信道进行仿真验证,从而了解信道的性能,为系统仿真提供仿真数据,为以后的实际应用打下基础,达到预研的目的。
And then , it presents changan star sc6350 abs uses three control channels , the control way is front wheel single controlling , and rear wheel is select - low control . the abs system makes the vehicle have good handleability and directional stability during the braking and shorts the braking distance 在此基础上，提出sc6350 “长安之星”的abs系统采用4传感器3通道型式，控制方式为前轮独立控制、后轮低选择同时控制，使汽车能够在制动过程中，确保转向操纵性，改善方向稳定性，缩短了制动距离。
But in the process of lessening the decoupling degree , the ranks of equivalent controlled channels will be augmented . thus , the reduced model is exploited in decoupling process in order to resume the plant prosperity which are distorded . it has greatly lessen the difficulty in group decoupling 本文结合生产实践，在分析系统耦合度的基础上，利用分组解耦来弱化系统的耦合度，并利用模型降阶方法简化解耦网络模型，较好地解决在逐次弱化过程中使解耦后的等效控制通道的阶次增大的问题。
