Abstract: A device of dynamic communication of information allows, on the average, non-integer bits per symbol transmission, using a compact code set or a partial response decoding receiver. A stream of selectable predetermined integer bits, e.g., k or k+1 data bits, is grouped into a selectable integer number of bit vectors which then are mapped onto corresponding signal constellations forming transmission symbols. Two or more symbols can be grouped and further encoded, so that a symbol is spread across the two or more symbols being communicated. Sequence estimation using, for example, maximum likelihood techniques, as informed by noise estimates relative to the received signal. Each branch metric in computing the path metric of a considered sequence at the receiver is weighted by the inverse of the noise power. It is desirable that the constellation selection, sequence estimation and noise estimation be performed continuously and dynamically.

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 integrated burst FSK receiver is provided to receive and interpret an RF signal using FSK modulation. The integrated burst FSK receiver uses a programmable RF local oscillator to mix a received signal down to an IF range or baseband, where it is filtered and sampled for subsequent digital processing. Digital filtering and detection are employed to improve overall bit error rate performance and receiver sensitivity. A programmable digital low-pass or band-pass filter can also be used to suppress interference. A matched filter correlator can be used for detection and symbol timing adjustment in one mode, while an adaptive frequency comparator can be used in another mode. Circuits are provided that estimate carrier offset, frequency deviation and signal strength. These measurements can then be used to optimize the receiver performance. A method for receiving and interpreting an RF signal using FSK modulation is also provided.

Abstract: A communications system, having a combination Reed-Solomon encoder and a Turbo-Code encoder Data frame configuration which may be changed to accommodate embedded submarkers of known value. The submarkers are embedded in with the data order to aid synchronization in the receiver system, by providing strings of known symbols. The string of known symbols may be the same as the symbols within a training header that appears at the beginning of a data frame. Frame parameters may be tailored to individual users and may be controlled by information pertaining to receivers, such as bit error rate of the receiver. Additional headers may be interspersed within the data in order to assist in receiver synchronization. Frames of data may be acquired quickly by a receiver by having a string of symbols representing the phase offset between successive header symbols in the header training sequence in order to determine the carrier offset. Phase lock to a signal may be achieved after determining carrier offset in receivers by correlating successive symbols in successive headers.

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: All digital RF modulator. An RF modulator, implemented using only digital techniques, obviates the need for an additional board, implemented using discrete analog components, to perform the necessary modulation to provide the RF output signal for use with a display device (television). Modern displays typically include functionality to support a number of input types beyond an RF input. However, older, legacy displays typically only support inputs that are RF in nature. A fully integrated solution that performs the RF modulation of the output signal that may be used in such legacy types systems is provided using digital techniques.

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.
