摘要： Physical layer (PHY) sub-channel processing. A soft symbol decision stream is arranged into a number of sub-channels to reduce substantially the processing performed within a communication receiver on data that is not intended for that communication receiver. In other embodiments, a predetermined approach is employed to arrange the soft symbol decision stream into one or more frames; each frame may have one or more soft symbol blocks; and each soft symbol block may have one or more symbols. Each of the soft symbol blocks, within a frame, may be assigned to a sub-channel. Only the soft symbol blocks that contain information destined for the communication receiver need be decoded. Only the sub-channel that includes these soft symbol blocks, destined for this communication receiver, need be decoded. The soft symbol blocks not within the sub-channel may be discarded thereby recovering some of the processing capabilities of the communication receiver.

摘要： Communications signal transcoder. A solution is provided to transcode a signal from a first signal type to a second signal type to ensure proper interfacing between devices that may operate using different signal types. For example, within a communication system, a first signal type (having a first modulation type, e.g., 8 PSK) may be received. The transcoder then ensures that this signal, after it has undergone any initial processing (such as tuning, down-converting, decoding, and so on), is encoded into a second signal type (having a second modulation type, e.g., QPSK) such that it can interface properly with a device for which the received signal is intended. This transcoder functionality may be implemented within discrete components, or it may alternatively be integrated within a functional block of an integrated circuit. This functionality may be implemented in a variety of communication systems including satellite, cable television, Internet, and others.

摘要： Provided is a packet network adapter operable to receive a satellite intermediate frequency (IF) signal and determine whether the satellite IF signal includes DVB content based upon a network client request. When the satellite IF signal includes the requested DVB content, the satellite network adapter produces packetized data for delivery of the digital content to a network client or clients based upon the network client request.

摘要： Sample rate reduction in data communication receivers. Digital sampling of analog data is performed using a reduced sample rate. The reduction factor may be any number of factors including a factor that divides the sample rate by a factor of two. The reduction of the sampling frequency is from a sampling frequency that is greater than twice the highest frequency component in an analog input signal. These analog input signals may be I and Q streams in certain embodiments. A digital interpolation filter may be employed to increase (up-convert) the sample rate of a digital signal before it is input to a VID filter that is used to recover the transmitted symbols from the over-sampled data stream. In this embodiment, this technique allows a front end of a communication receiver to be clocked at a lower sampling rate without affecting the performance of the VID filter.

摘要： Interleaver for iterative decoder. A memory management scheme allows for single plane/single port memory devices to be used by the interleaver. The design is adaptable to soft-in soft-out (SISO) decoders that perform iterative decoding. The interleaver may be implemented within communication devices that implement two distinct SISOs that operate cooperatively or within communication devices that employ a single SISO (in a recycled embodiment) that functionally performs the analogous decoding operations that would be performed by the two distinct SISO implementation. The use of single plane/single port memory devices by the interleaver allows for a great deal of savings from many perspectives: the sizes of the required interleaver memory and the interleaver pattern memory are both cut in half using this approach, and a cost savings may also be realized, in that, cheaper, slower memories may be used since each respective interleaver memory is read only every other cycle.
摘要翻译：交织器用于迭代解码器。存储器管理方案允许单平面/单端口存储器件由交织器使用。该设计适用于执行迭代解码的软进软（SISO）解码器。交织器可以在实现两个不同的SISO的通信设备中实现，这两个SISO协作地或在使用在功能上执行由两个不同的SISO实现执行的类似解码操作的单个SISO（在回收的实施例中）的通信设备内。通过交织器使用单平面/单端口存储器件允许从许多角度大量节省：使用这种方法所需的交织器存储器和交织器模式存储器的尺寸都被削减了一半，并且可以节省成本也可以实现，由于每个相应的交织器存储器仅在每隔一个周期读取，所以可以使用更便宜的较慢的存储器。

摘要： A method and apparatus is disclosed to restrict the delivery of video, audio, and/or data to unauthorized end users in a satellite communications system. The satellite communications system includes one or more satellite receiving antennas, commonly referred to as a satellite dish, to receive downlink communications signals from one or more satellites. The transmission received by the one or more satellite receiving antennas is converted by an outdoor unit (ODU) for transmission to one or more indoor units (IDUs). The ODU receives control information from one or more satellites from the downlink communications signals, commonly referred to as in-band, and/or from out-of-band communications signals. The ODU may use the control information to restrict access to one or more communications channels embedded within the downlink communications signals to the unauthorized end users.
