    • A method for tracking memory changes includes defining a change-track area of memory including at least one memory address range for which changes will be tracked. The method also includes allocating a protected log region of memory for storing a change- track log and selecting an operational mode for change tracking from among a plurality of modes, the selected operational mode having criteria for tracking memory changes. The method includes detecting memory transactions using a memory logging module and generating a transaction record for each memory transaction that occurs in the change- track are of memory and which meets the criteria. The transaction records can be stored in the change-track log.
    • 用于跟踪存储器改变的方法包括定义存储器的改变轨道区域,其包括至少一个将被跟踪改变的存储器地址范围。 该方法还包括分配用于存储更改轨道日志的存储器的受保护对准区域,并且从多个模式中选择用于变化追踪的操作模式,所选择的操作模式具有跟踪存储器改变的准则。 该方法包括使用存储器记录模块来检测存储器事务,并且为存储器的变化轨迹中发生的并且符合标准的每个存储器事务生成事务记录。 事务记录可以存储在更改轨道日志中。

    • A satellite communication system processes a plurality of input signals to generate beamformed signals, drives a plurality of nonlinear power amplifiers with the beamformed input signals to produce RF signals for transmission; and transmits the RF signals with a plurality of Tx antenna elements. Conversion to and from linear signals to and from nonlinear or digitized signals is performed. Temporal or spatial decorrelation of the beamformed signals is employed to reduce the impact of intermodulation products. In some cases the power amplifiers are nonlinear, and can be one-sided or two-sided and produce two or three distinct output levels.
    • 卫星通信系统处理多个输入信号以生成波束形成的信号,用波束形成的输入信号驱动多个非线性功率放大器以产生用于传输的RF信号; 并且用多个Tx天线元件发送RF信号。 将线性信号转换为非线性或数字信号以及从非线性或数字信号转换为线性信号。 采用波束形成信号的时间或空间去相关来减少互调产物的影响。 在某些情况下,功率放大器是非线性的,可以是单侧或双侧的,产生两到三个不同的输出电平。
