摘要： A modem communication system with receiving and transmission paths includes a direct equalizer system having an adaptive filter (1532) in the transmission path to compensate for frequency distortion of the communication channel. The transmitter filter coefficients are adapted by a filter coefficient calculator (1528), under control of a data detector (1526) which detects incoming data in the receiving path. A switch (1534) is controlled by status of a transmit output data buffer to multiplex either the training sequence or output data into the transmission path. When the buffer is idle, the training sequence generator (1540) is linked to a digital-to-analog (D/A) converter (1536) and line driver (1538). The receiving path includes an isolation switch (1520), a receiver amplifier (1522) and a slicer (1524). The receiver correlates the received training sequence with a known training sequence and updates the equalizer filter coefficients using an adaptation algorithm, such as a least mean squared algorithm. A first embodiment utilizes a high speed digital programmable filter (1532). Another embodiment utilizes a data buffer (1533) which is periodically filled with data filtered by a digital signal processor (DSP).

摘要： A method (50) of communicating bit groups between a first DSL modem (M14) and a second DSL modem (M12). The method receives (56) at the first DSL modem a plurality of bit groups (FF1-FF500) from the second DSL modem. Each of the plurality of bit groups comprises a plurality of bit sub-groups (W1-W12), and each of the plurality of bit sub-groups has an order of location. For each of the plurality of bit groups, the method determines (58) whether bits of at least one sub-group having a common order of location comprise at least one erroneous bit. In response to this determination, the method stores (62, 64) in the first DSL modem a record (InMaskBuff) of whether the at least one sub-group having the common order of location comprises at least one erroneous bit. From this record, various other steps (72) may be taken in the preferred embodiment, including suppressing (82) the at least one sub-group from communicating valid information from the second DSL modem to the first DSL modem.

摘要： A multi-client ADSL modem network (10) that can be configured for a home or office network when multiple ADSL client modems (18) are installed in different communication terminals (22). One ADSL modem (14) at a central office (12) coordinates the remote multi-client modems (18) for communication over a single twisted pair loop carrier phone line (16), allowing the connected modems (18) to communicate not only with the CO modem (14), but also with each other by sharing frames, tones, or by code division techniques on upstream channels. The CO modem (14) operates as a network hub and/or arbitrator, and facilitates one ADSL modem to become the master modem and maintain a superframe. The present invention provides home network ADSL service without extra wiring or equipment, thus providing a low cost approach for home networking of ADSL service.

摘要： A DMT device having an analog front end for receiving an analog signal, a converter for converting the analog signal to a digital signal, a FFT for converting the digital signal from the time domain to the frequency domain and feeding the digital signal to a frequency domain equalizer having variable coefficients for flattening the converted digital signal. The frequency domain equalizer includes a gain corrector coupled to the FFT to compensate the channel frequency rolloff and make each tone approximately the same amplitude before phase rotation and a phase rotator portion responsive to the output of the gain corrector to track small channel variation. Also included is circuitry for updating the coefficients of the frequency domain equalizer, preferably in the form of a slicer for controlling the frequency domain equalizer by feeding back an error signal thereto. The error signal is preferably fed back to the phase rotator portion of the frequency domain equalizer.

摘要： The method for power control in HSDPA includes Step A, the UE with the highest priority and having data to be transmitted is selected according to the algorithm, the channel resource is distributed to the UE, and the original power level is set. Step B, the transmission power is deduced when the channel quality meets the condition; Otherwise the CQI is checked, if the value of CQI is under the highest rate level, or the data is the re-transmitting data, the transmission power is increased, or the power is kept the same level. Step C, channel resource and the UE with the highest priority are checked, if there exist, then go to step B, otherwise the method is ended. So the redundant power can be used when several UEs are controlled at the same time, the efficiency and the throughput performance are improved, and the interface is reduced. The device for power controlling is given at the same time.
