摘要： Applicants have discovered that error detection techniques, such as Forward Error Correction techniques, may be used 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.

摘要： Systems and methods are disclosed for adapting a communication system to varying conditions. Using some form of discovery protocol, the communication standards supported by at least two communicants are determined. Each communicant may then periodically monitor the quality of the channel established by the communication standard and dynamically select a set of one or more communication standards to use for communicating. Further, when communicants share common non-standard parameterized implementations of communication standards, changes to the protocols which the communication standards comprise can be used to add options for a more dynamic response to changing conditions than is possible when adhering only to an established communication standard.

摘要： Systems and methods are provided for modularly constructing a software defined radio (“SDR”). Given 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), an optional description of governmental regulations for a particular locality, and an interface harness providing the necessary components for interfacing to specific communication channels and devices (including SDR hardware components), an SDR factory component performs a process of constructing an SDR software component for implementing a particular radio standard on a particular host. The SDR software component may additionally construct components which restrict the operation of the resulting SDR software component. The SDR kernel may be protected by one or more digital rights management (“DRM”) policies which may be enforced both at the time the SDR software component is constructed and while it is operating.

摘要： 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.

摘要： A multiuser scheme allowing for a number of users, sets of user, or carriers to share one or more channels is provided. In the invention, the available channel bandwidth is subdivided into a number of equal-bandwidth subchannels according to standard OFDM practice. The transmitter is informed by an application that it needs to transmit data a particular rate. The transmitter determines the minimum number of subchannels and maximum energy (or noise) threshold for each subchannel necessary to achieve that data rate and selects a set of subchannels matching those requirements. The subchannels need not be contiguous in the spectrum or belong to the same channel. Once the transmitter has selected the required number of subchannels, it begins transmitting simultaneously on those subchannels across the entire bandwidth used by those subchannels.
摘要翻译：提供允许多个用户，一组用户或运营商共享一个或多个信道的多用户方案。在本发明中，可用信道带宽根据标准OFDM实践被细分为多个等带宽子信道。发射机被应用程序通知它需要以特定速率传输数据。发射机确定实现该数据速率所需的每个子信道的子信道的最小数目和最大能量（或噪声）阈值，并选择一组符合这些要求的子信道。子信道不需要在频谱中是连续的或属于同一信道。一旦发射机选择了所需数量的子信道，它将在这些子信道使用的整个带宽上在这些子信道上同时开始传输。
