1.It suggests LTE will emerge as the leading 4G technology, rather than WiMax or Ultra Mobile Broadband, which are the main alternatives.
这意味着成为4G领先技术的将是LTE，而非其主要竞争对手WiMax或超移动宽带（UMB）。
2.And the capacity of the UMB systems has been greatly improved by using the multiple antenna technology, like the Closed-loop MIMO.
还有闭环MIMO等多天线技术的使用，使得UMB系统的系统容量有了极大的提升。
3.The simulation platform is built by using MATLAB to assess the performance of the UMB systems'physical layer.
通过使用MATLAB搭建仿真平台，评估UMB系统物理层的性能。
4.double - buffering driver cannot be loaded into a umb
双缓冲驱动程序不能装入umb。
