    • A modem operating selectively in the voice frequency and higher frequency bands which supports multiple line codes. A DSP is used to implement different existing ADSL line codes on the same hardware platform. The modem negotiates in real time for a desired line transmission rate to accommodate line condition and service cost requirements which may be implemented at the beginning of each communication session by exchange of tones between modems. A four step MDSL modem initialization process provides line code and rate compatibility. The handshake protocol and receiver algorithm for CAP based MDSL modems allows reliable modem synchronization over severely amplitude distorted channels and makes use of a short length sequence to train a synchronizing equalizer at the receiver. The algorithm and corresponding training sequence to train the transmitter filter are provided. After training to this sequence, a matched filter or correlator detects the inverted sync sequence. Detection of the inverted sequence signals commencement of normal reference training of the demodulation equalizers. An internal state machine in an MDSL modem records and monitors line status and notifies state change to other MDSL and host processor. The protocol for exchanging line connection management messages is a simplified LCP for MDSL. In a DMT system, a transmitter filter reduces the length of effective channel impulse response. Iimplementation of the filter combines time domain convolution and frequency domain multiplication to reduce needed computation power. The filter coefficients update may occur through a feedback channel.

    • 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.
