    • Systems and methods are provided that disclose a network service for modularly constructing a software defined radio (“SDR”). A server system provides an SDR kernel (i.e., a potentially platform-neutral definition of digital signal processing functionality and control operations necessary to implement the core portion of a software defined radio implementing a particular radio standard) to a client system. The client system may select a desired SDR kernel through a variety of means disclosed herein. While some SDR kernels may be provided for free and unrestricted use, others may be purchased or subscribed to and additionally restricted by digital rights management (“DRM”) policies. Based upon the agreed upon payment terms and any other restrictions, a customized set of DRM policies may be applied by the server system to the SDR kernel before sending it to a client system. Additionally, the server system may provide a description of governmental regulations applicable to a given locality.
    • 提供了公开用于模块化构建软件定义无线电(SDR)的网络服务的系统和方法。 服务器系统向客户端系统提供SDR内核(即,数字信号处理功能的潜在平台中立定义和实现特定无线电标准的软件定义的无线电的核心部分所必需的控制操作)。 客户端系统可以通过本文公开的各种手段来选择期望的SDR内核。 虽然一些SDR内核可能被提供为免费和不受限制的使用,但是其他可以被数字版权管理(DRM)策略购买或订阅并且另外受到限制。 根据约定的付款条件和任何其他限制,服务器系统可以将定制的一组DRM策略应用于SDR内核,然后将其发送到客户端系统。 此外,服务器系统可以提供适用于给定地点的政府规章的描述。

    • Methods and apparatus are disclosed for using error detection techniques, such as Forward Error Correction techniques, to predict the degradation below a certain threshold of an ability to accurately convey information on a communication channel, for example, to predict a failure of the communication channel. In response, transmission and/or reception of information on the channel may be adapted, for example, to prevent the degradation below the threshold, e.g., prevent channel failure. Predicting the degradation may be based, at least in part, on data transmission error information corresponding to one or more blocks of information received on the channel and may include determining an error rate pattern over time. Based on these determinations, the degradation below the threshold may be predicted and the transmission and/or reception adapted. Adapting may include initiating use of a different error encoding scheme and/or using an additional communication channel to convey information.
    • 公开了使用错误检测技术(例如前向纠错技术)的方法和装置来预测在通信信道上准确地传送信息的能力的某一阈​​值以下的劣化,例如预测通信信道的故障。 作为响应,信道上的信息的传输和/或接收可以适应于例如防止劣化到阈值以下,例如防止信道故障。 可以至少部分地基于与信道上接收的一个或多个信息块相对应的数据传输错误信息来预测劣化,并且可以包括随时间确定错误率模式。 基于这些确定,可以预测低于阈值的劣化,并且传输和/或接收适应。 适应可以包括启动使用不同的错误编码方案和/或使用附加通信信道来传达信息。
