Abstract: A communication device is implemented to perform signal processing based on different dynamic ranges at different times. The device can operate with a first, relatively larger dynamic range during normal operations, and with a second, relatively smaller dynamic range during reduced power or sleep mode operations. The relatively smaller dynamic range may have a relatively higher noise floor than the larger dynamic range. Generally, any desired number of different dynamic ranges may be used at different times and based on different operating conditions. The communication device can include functionality associated with two or more transceivers to support communications based on two or more power modes (e.g., a full power mode, a reduced power mode or a sleep mode, etc.). The communication device may alternatively include two or more separate transceivers to support such communications. An unused transceiver or transceiver functionality may be turned off to provide power savings.

Abstract: Many communication systems operate based on orthogonal frequency division multiplexing (OFDM) signaling and/or orthogonal frequency division multiple access (OFDMA) signaling. Within such systems, narrowband interference, which may alternatively be referred to as narrowband ingress, narrowband ingress interference, narrowband noise, etc., may adversely affect one or more subcarriers or tones causing a reduction in performance or even link failure. Such narrowband interference may affect only one or a relatively few tones employed within such communications. When the narrowband interference is identified, a transmission may then be made including one or more information-free tones. A device that receives such a transmission then uses those information-free tones to reduce or cancel the narrowband interference. Such processing may be performed in the frequency-domain, the time domain, or both.

Abstract: An outer encoder encodes input data signal to generate a first encoded signal. An inner encoder encodes a subset of the input data to generate a second encoded signal, wherein the inner encoder has a different forward error correction (FEC) than the outer encoder. A symbol mapper processes the first encoded signal and the second encoded signal to generate a sequence of discrete-valued modulation symbols.

Abstract: Spectrum analysis (SA) capability is included in various communication devices within a communication network. One or more of the devices use the SA information from other devices in the system to determine status of various communication links were devices in the system. One or more processors within one or more devices can identify any actual/existing or expected failure or degradation of the various components within the system. Such components may include communication devices, communication channels or links, interfaces, interconnections, etc. When an actual/existing or expected failure or degradation is identified, the affected components may be serviced or devices within the system may operate to mitigate any reduction in performance caused by such problems. Such SA functionality/capability may be implemented in one communication device or in a distributed manner across a number of devices in a communication system.

Abstract: A communication device is configured to perform interleaving of a modulation symbol sequence to generate an OFDM symbol. Some modulation symbols within the modulation symbol sequence that are separated by an interleaver depth may be transmitted via adjacently located sub-carriers, while other modulation symbols within the modulation sequence that are separated by more than the interleaver depth may also be transmitted via adjacently located sub-carriers. First adjacently located sub-carriers transmit first and second modulation symbols that are separated by the interleaver depth within the modulation sequence while second adjacently located sub-carriers transmit third and fourth modulation symbol that are separated by more than the interleaver depth within the modulation sequence. A communication device may be configured to adapt and switch between different operational parameters used for interleaving and/or deinterleaving at different times based on any desired considerations.

Abstract: A communication system includes a supervisory node (e.g., a headend) and one or more remote nodes (e.g., cable modems). The supervisory node or a remote node monitors a characteristic associated with the communication system. Remote node transmits an upstream communication among a plurality of physical upstream channels based on the characteristic. The average transmit power used to transmit the upstream communication among the plurality of physical upstream channels is no greater than the average transmit power that would be necessary to transmit the upstream communication using a single physical upstream channel at a lower data rate.

Abstract: A demodulator processes a continuous-time signal to generate at a plurality of encoded bits. An inner decoder processes a first subset of bits within the plurality of encoded bits to correct selected ones of the first subset of bits to form a corrected first subset of bits and to generate partially corrected data from the plurality of encoded bits based on the corrected first subset of bits. An outer decoder processes the partially decoded data, to correct selected ones of a second subset of the plurality of encoded bits to form a corrected second subset of bits. A bit combiner generates data estimates by combining the corrected first subset of bits and the corrected second subset of bits.

Abstract: Signal processing under attenuated transmission conditions. Within an orthogonal signal space, the number of orthogonal signals that are used to transmit information from a transmitter to a receiver is reduced and the transmitted power of each of the now remaining orthogonal signals is modified; this may involve increasing the power of all of the remaining orthogonal signals equally or alternatively modifying them individually. The same modulation used before the reduction may also be used afterwards; within communication systems having multiple transmitter-receiver paths, this will ensure that the communication system's throughput and efficiency will remain unchanged even when one (or more) transmitter-receiver paths are highly attenuated. In addition, robust mode operation is provided for ranging and registering of transmitter devices when entering the communication system. In addition, the unused orthogonal signals may be employed to support interference cancellation of those orthogonal signals that are used to transmit information.

Abstract: A communication device is configured to perform symbol mapping of bits to generate modulation symbols using one or more modulations. The device may employ a blended modulation composed of bit labels or symbols having different numbers of bits per symbol and different modulations. For example, the device may symbol map bit labels/symbols having first number of bits per symbol to first modulation, and the device may symbol map labels/symbols having second number of bits per symbol to second modulation. The device may be configured to perform forward error correction (FEC) or error correction code (ECC) and coding of information bits to generate coded bits that subsequently undergo symbol mapping. The device may be configured to operate based on different operational modes based on substantially uniform steps of rates, or bits per symbol, and energy per bit or symbol to noise spectral density ratio (Eb/N0 or Es/N0).
