After be being adjusted this, associate Milko Van Duij of senior vice president takes up the post of business of market of this group maturity to get a soldier, apparent this kind of arrangement is to be play abroad the good qualities of tall canal; And to latin america market, the antenna that associate is extended not quite longly still, hold Rory Read of presiding operation official concurrently to present as leading role by the president, apparent intention depends on cultivating the market.
此次调整后，联想高级副总裁Milko Van Duij出任该集团成熟市场业务领军人，显然这种安排是为发挥海外高管的长处；而对于拉丁美洲市场，联想的触角伸得还不够长，由总裁兼首席运营官Rory Read领衔，显然意图在于培育市场。
Firstly, the differences between the ultra-wideband antenna and conventional wideband antenna are introduced in this thesis, and the definitions of several performance parameters of the ultra-wideband antenna are presented, among which the phase center and the group delay time are primarily discussed in that they describe the time domain properties of the antenna.

Methods Forty-four EBTB patients weredivided into an experiment group and a control group. All the patients of the two groups were treated with generalchemotherapy, the patients of experiment group accepted endobronehial decimeter wave therapy at the same time. Thepurulent secretion or caseous necrosis of the diseased region was drawn-off from the bronchi lumina by bronchoseope, then the antenna of the decimeter wave irradiator was inserted into the diseased region through the biopsy pore to per-form the radiation.

For the reason that the antenna number of the relay node is only half the total number of single-antenna users which means the antenna num-ber of the relay node is less than the total number of users, beamforming at cancelling intra-group interference is no longer applicable.
由于中继天线数目只为单天线用户总数的一半，中继天线数目小于用户总数，因此旨在消除组间干扰的波束成形方案不再适用。
In addition, MMSE IC iterative group detection combined with power allocation among different antenna layers can further improve the system performance. Secondly, distributed generalized low-density codes are proposed for the clustered cooperative relay networks.
此外，MMSEIC迭代群检测算法结合天线层之间的功率分配也可进一步改善系统性能。其次，针对成簇的协作中继网络，提出基于分布式广义低密度码的协作传输方案。
