U－BOOT是嵌入式系统里面比较常用的bootloader，支持许多平台，比如ARM，PPC等。这个文章详细描述了讲U－BOOT移植到44B0平台的步骤-U-BOOT system is embedded inside the commonest Bootloader. support many platforms, such as ARM, PPC, and so on. This article describes the stresses U-BOOT transplant 44 B0 platform steps

摘要:基于通信技术的列车运行控制系统(CBTC)是铁路信号的发展方向，交频分复用 OFDM)是一种无线环境下的高速传输技术，它对高速列车控制信息传输中卞要受到的由于多 径传播引起的快衰落所产生的影响有很强的抵抗能力.本文首先介绍了OFDM技术的发展和 基本原理，然后在计算机上用M atlal〕对其性能进行了仿真，仿真中将OFDM与传统的单载波 调制方式―i1，交振幅调制( 1frQAM)对抗多径十扰的性能进行了比较，最后分析了一者的仿真结果. -Abstract: Based on the communication technology train operation control system (CBTC) is a railway signal direction for the development of cross-frequency division multiplexing OFDM) is a wireless environment of high-speed transmission technology, its high-speed train control information transmission Bian be subject to the Due to the spread of multi-path fast fading caused by the impact of a strong resistance to diseases. This paper first introduces the OFDM technology development and the basic principles, and then on the computer〕 M atlal use its performance simulation will OFDM with the traditional single-carrier modulation-i1, cross-amplitude modulation (1frQAM) against multi-path interference of the 10 properties were compared with a final analysis of

在本论文中我们根据3GPP协议TR25.813,25.814，25.913和25.914的要求和参数，设计搭建了一个基于SC-FDMA的准静态系统级仿真器. -In this paper, we according to 3GPP agreement TR25.813, 25.814,25.913 and 25.914 of the requirements and parameters, designed to build an SC-FDMA-based quasi-static system-level simulator.

顺序图和状态图被用来描述系统组建的特征，本来提出一种基于顺序图和状态图的协调性模型，用来更好得保证系统的时间特性。-sequence map and the state plan to be used to describe the characteristics of the formation system, originally proposed a plan based on the order of the state plan and the coordination model, used to guarantee better in the time characteristics.
