In this dissertation, a theorem to describe the relationship between the quotient group Aut/H and the set F_f is presented. And a way to find the elements of F_f that are conjugate to f is proposed. Then we prove that the quotient group Aut/H is isomorphic to S_3, the symmetric group of order 3, and H is a semidirect product group of GL_(m/2)(4) with the classical binary simplex code S_m in the linear case.

本文刻画了商群Aut／H与集合F_f的关系，给出了一个确定集合F_f中那些与f共轭的元素的方法，还证明了在线性情形下，商群Aut／H与3阶对称群S_3是同构的，而且H是GL_(m/2)(4)与经典单形码S_m的一个半直积，并且推关广了Calderbank等人的一个结果。

The invention discloses a method for dynamic channel allocation in TDD-CDMA mobile communication system. Based on the distance between mobile station and subzone base station BS, mobile stations MS are classified. Code tract in same group of code track (carrier frequency + time slot) is allocated to the mobile station with nearer distance. MS with different distances have different requirements of emission power. Whether crossed time slot code track group can be used or not, and use of group of code track with what kind of multiplexing factor need to be determined.

本发明公开了一种TDD－CDMA移动通信系统的动态信道分配方法，是将移动台MS按照与本小区基站BS的距离进行分类，同一个码道组中的码道分配给距离相近的移动台MS；同时不同距离的MS对发射功率的要求不同，对相邻小区的干扰也不同，系统根据MS对发射功率的要求，确定其是否可以使用交叉时隙码道组和使用哪种复用因子的码道组。

In order to effectively reduce the effects of multi-access interference on the performance of optical code division multiple access communication systems with intensity modulation and direct detection,according to group information, a novel kind of multi-access interference cancellation scheme based on fiber Bragg gratingused with two dimensional address code MPC/OOC is presented.

摘要在强度调制、直接探测的光码分多址通信系统中，为了有效克服并发用户数之间的多址干扰，提高系统的通信性能，根据组信息，针对由光正交码和修正素数码构成的扩时/跳频地址码MPC/OOC，提出一种基于光纤布拉格光栅的多址干扰消除方案，并详细分析了采用这种多址干扰消除方案的光CDMA通信系统的性能。

"I used to live in terror of the unknown, but I've realized that you can't control things," says Kathryn, who sang in her family's gospel music group, Morris Code, as a child. You have to surrender and believe that things will be taken care of by God or the universe. If you put yourself out there and you're doing something active to break patterns, you will get something that you wouldn't have gotten if you didn't step outside the box.

&我曾经生活在对于未知的恐惧中，但后来我意识到，你必须能控制事情的发展&KM说（KM小时候层跟随她的家庭福音合唱团——Morris Code一起四处演唱）你必须承认和相信时间万物将被上帝和宇宙所掌控，如果你把自己置身之外，并且做一些打破常规的事，你将会受到一些你本不会受到的惩罚。
