Abstract: 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.

Abstract: 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.

Abstract: An adaptive receiver is disclosed for optimally receiving and processing signals. The receiver utilizes one or more memory blocks to store groups of incoming symbols. The groups of symbols are processed by a channel estimation subsystem to determine channel characteristics. The receiver determines the appropriate demodulation and decoding strategy to implement based on the determined channel characteristics. The receiver includes a plurality of demodulation and decoding schemes, one of which is selected based on the results of a channel estimation analysis.

Abstract: An apparatus provides a local oscillator signal based on a selected channel of an RF input signal. For example, the apparatus can set a frequency of the local oscillator signal based on the selected channel. Digital circuitry can be used to generate the local oscillator signal. For instance, the digital circuitry can provide a digital representation of the local oscillator signal. A DAC can convert the digital representation to an analog signal. Other circuitry can provide first and second quadrature components of the local oscillator signal, based on the analog signal.

Abstract: FEC (Forward Error Correction) decoder with dynamic parameters. A novel means by which FEC parameters may be encoded into, and subsequently extracted from, a signal stream to allow for adaptive changing of any 1 or more operational parameters that govern communications across a communication channel. FEC parameters are encoded directly into a data frame such that the data frame is treated identical to all other data frames within the signal stream. When the data frame actually includes FEC parameters, it is characterized as a CP (Control Packet) type. For example, when decoding an MPEG stream, an MPEG block that includes FEC parameters, that MPEG block is characterized as a CP MPEG block. The means by which FEC parameters are encoded and extracted from the signal stream allows for much easier adaptive modification of the manner by which signal are encoded, modulated, and processed within a communication system.

Abstract: A receiver to process a RF input signal having a plurality of channels includes a direct down conversion circuit, a demodulation circuit, and a local oscillator circuit. The direct down conversion circuit provides a downconverted signal based on the RF input signal and a local oscillator signal. The demodulation circuit receives the downconverted signal and provides a demodulated signal. The local oscillator circuit sets a frequency of the local oscillator signal based on a selected channel of the plurality of channels.

Abstract: Various multi-lane ADCs are disclosed that substantially compensate for impairments present within various signals that result from various impairments, such as phase offset, amplitude offset, and/or DC offset to provide some examples, such that their respective digital output samples accurately represent their respective analog inputs. Generally, the various multi-lane ADCs determine various statistical relationships, such as various correlations to provide an example, between these various signals and various known calibration signals to quantify the phase offset, amplitude offset, and/or DC offset that may be present within the various signals. The various multi-lane ADCs adjust the various signals to substantially compensate for the phase offset, amplitude offset, and/or DC offset based upon these various statistical relationships such that their respective digital output samples accurately represent their respective analog inputs.
