Abstract: Aspects of compensating for transmitter output power may comprise sampling an on-chip transmitter circuit temperature at various time instants and determining a feedback temperature compensation value. At least one digital-to-analog converter may be adjusted by utilizing the feedback temperature compensation value, which may correspond to the sampled temperature. The digital-to-analog converter may be an I-component digital-to-analog converter and/or a Q-component digital-to-analog converter. At least a portion of the on-chip transmitter circuit may be characterized to determine power output dependence of the on-chip transmitter circuit on temperature variation of the on-chip transmitter circuit. Based on this characterization, a feedback temperature compensation value that may correspond to the sampled temperature may be used to adjust the digital-to-analog converter. The feedback temperature compensation value may be, for example, from a lookup table or an algorithm.

Abstract: A method and computer program product for providing RTP suppression across a DOCSIS network. An index number and a set of rules are sent to a receiver. The index number indicates the type of header suppression technique (i.e., RTP header suppression) to be performed, and the set of rules define how to recreate the RTP packets on the receiving end. At least one complete RTP packet is transmitted upstream for enabling a receiver to learn the RTP header. Subsequent RTP packets are transmitted upstream for reconstruction at the receiving end. The subsequent RTP packets are comprised of delta values representing fields that dynamically change from packet to packet in an RTP header.

Abstract: Methods and systems for modifying DOCSIS-based transmission paths for communication in higher frequency and/or wireless environments, such as wireless terrestrial communication systems and satellite communication systems. An inner turbo-code is combined with a DOCSIS based Reed-Solomon (“RS”) forward error correction (“FEC”) coding scheme, to produce a concatenated turbo-RS code (other FEC codes can be utilized). In phase and quadrature phase (“I-Q”) processing is utilized to enable relatively low cost up-converter implementations. The I-Q processing is preferably performed at baseband, essentially pre-compensating for analog variations in the transmit path. Power amplifier on/off control capable of controlling on/off RF power control of remote transmitters is modulated on a transmit cable to reduce the need for a separate cable.

Abstract: A method for determining beamforming coefficients begins by obtaining channel information for a multiple tone communication. The method then continues by deriving the beamforming coefficients based on the channel information and a smoothness criteria.

Abstract: Certain aspects of a method and system for transparent transmission control protocol (TCP) offload with best effort direct placement of incoming traffic are disclosed. Aspects of a method may include collecting TCP segments in a network interface card (NIC) processor without transferring state information to a host processor every time a TCP segment is received. When an event occurs that terminates the collection of TCP segments, the NIC processor may generate a new aggregated TCP segment based on the collected TCP segments. If a placement sequence number corresponding to the generated new TCP segment for the particular network flow is received before the TCP segment is received, the generated new TCP segment may be transferred directly from the memory to the user buffer instead of transferring the data to a kernel buffer, which would require further copy by the host stack from kernel buffer to user buffer.

Abstract: Separation of luma and chroma in a video. In an embodiment, values on a current line of the sampled video signal, at ¼-period intervals, are compared with values on a previous line of the sampled video signal, at ¼-period intervals. Values on the current line of the sampled video signal are compared to values on a subsequent line of the sampled video signal. This gives information about the vertical frequency content. Values on the current line are compared with values having the same chroma phase on the same line to provide information about horizontal frequency content. The data of vertical and horizontal frequency logic are used by the decision logic to determine the appropriateness of combing based on these comparisons. If combing is not appropriate, the signal is bandpass filtered instead of combed. The low-pass and combing filters are applied to the original signal, not an interpolated or resampled signal.

Abstract: A cable modem method, system, and computer program product are provided for payload header suppression in which a limited number of suppression indices is used to map suppression rules to data streams. Network resources are conserved by implementing precise classification algorithms to correctly identify incoming packets at the cable modem as belonging to a particular data stream, which ensures that a minimum number of suppression indices are utilized. Additionally, network resources are conserved by utilizing sophisticated algorithms for reusing suppression indices when new data streams are detected by the cable modem. One such reuse algorithm involves recycling the suppression index that has been least recently used in transmitting a packet with a suppressed payload header.
