摘要： A method and apparatus are provided for implementing soft-input soft-output iterative detectors/decoders. Soft-input information is added directly to incoming channel samples. Input signals comprising the received incoming channel samples with the added soft-input information are detected using a detector trellis. Branch metric terms are transformed to shift all time varying terms with the added soft-input information and some constant terms after an add compare select (ACS) unit. The shifted time varying terms with the added soft-input information and the shifted constant terms are added directly to state metric terms. The soft-input information is added directly to incoming channel samples and the computation of branch metrics is not affected. This allows optimization of a dual-max detector and soft-input soft-output Viterbi detector architectures to minimize hardware complexity and power consumption.

摘要： Systems, methods, and computer program products generate a DIL signal in which the length of the sign pattern used for symbols in the DIL signal is a positive integer that wholly divisible by four and is not wholly divisible by three. The sign pattern may be viewed as comprising both an even and an odd subsequence with the number of positive signs balancing the number of negative signs in each subsequence. The DIL signal may be distorted by analog impairments, such as transformers, that may introduce nulls at direct current (DC) and severe non-linear distortion below 100 Hz. Moreover, low-pass filters in the PSTN typically have a sharp roll-off at the Nyquist frequency of 4 kHz. A DIL signal that includes one or more DIL segments with each DIL segment incorporating the aforementioned sign pattern may be characterized by spectral nulls at both direct current (DC) and the Nyquist frequency, which is 4 kHz for a V.90 modem application.

摘要： Digital impairments, including Robbed Bit Signaling (RBS) and impairments due to digital attenuation PAD (Packet Assembler/Disassembler) devices, may be identified in sets of Pulse Code Modulation (PCM) signal levels, such as sets of Digital Impairment Learning (DIL) signals transmitted from a server modem to a client modem during a plurality of DIL levels. Both signature analysis and signal level comparison analysis are preformed on the signals to identify digital impairments. Signature analysis compresses the set of signal levels into a signature. Digital impairments are determined based on the signature. In a preferred embodiment, the PCM signal levels are compressed into a signature by identifying clusters and/or skips. PCM signal level comparison analysis uses differences, between PCM signals and models of signals having various digital impairments. By using both techniques combination, the strengths of each technique are utilized while the weaknesses of each techniques are avoided.

摘要： Methods, systems and computer program products are provided for refining constellation values in a Pulse Code Modulated (PCM) code point sequence of a PCM modem by averaging received levels associated with received symbols for a code point of interest received during data mode operation of the PCM modem so as to provide an average received level for the code point of interest and revising a constellation value corresponding to the code point of interest in the PCM code sequence based on the average received level for the code point of interest so as to provide a refined constellation value. Preferably, the averaging is performed by detecting that a symbol corresponding to the code point of interest has been received by the PCM modem and incorporating the received level of the symbol into a running sum of previously received levels for the symbol. If a predefined number of received levels have been incorporated into the running sum then the running sum is divided by the predefined number of receive levels. It is also preferred that, after determining the sum for the code point of interest, the running sum is set to zero and a new code point selected as the code point of interest.

摘要： One embodiment provides a method of managing power in a computer system. A device of the computer system is operated at a selected power-state. The power consumption of the computer system is monitored. If the power consumption of the computer system is approaching or has exceeded a power cap selected for the computer system, then a request to reduce the power-state for the device is generated in response. The operating system is used to service the request to reduce the power-state according to the priority of the request. The reduced power state is forced out-of-band following the request to reduce the power-state if the request is not immediately serviceable by the operating system. Different approaches can be taken to force the reduced power state, using, for example, system management mode or a platform environment control interface.
